本發明是有關於一種混凝土材料及其製造方法，且特別是有關於一種膠結材與其製造方法以及一種砂漿固化物與其製造方法。 The invention relates to a concrete material and a manufacturing method thereof, and in particular to a cemented material and a manufacturing method thereof and a mortar cured product and a manufacturing method thereof.
目前火力發電仍為台灣現階段的主要電力供應單元，而由火力發電廠中產生的燃煤飛灰約為200萬公噸。儘管近年來已將燃煤飛灰應用於膠結材的原料中，然而所形成的膠結材在抗壓強度及製造成本上無法得到均衡。 At present, thermal power generation is still the main power supply unit in Taiwan at this stage, and coal-fired fly ash generated by thermal power plants is about 2 million metric tons. Although coal-fired fly ash has been used as a raw material for cement in recent years, the resulting cement cannot be balanced in compressive strength and manufacturing cost.
因此，目前急需提供一種將飛灰應用於膠結材之技術，以在使製造成本降低的情況下保持或提升所形成的膠結材的抗壓強度，以增加其產業利用性。 Therefore, there is an urgent need to provide a technology for applying fly ash to cement materials to maintain or increase the compressive strength of the cement materials formed while reducing manufacturing costs, so as to increase its industrial applicability.

本發明提供一種砂漿固化物的製造方法，其包括下列步驟：提供鹼性溶液，其中鹼性溶液由氫氧化物及水組成；在鹼性溶液中加入飛灰及細粒料並攪拌，以形成砂漿；以及固化砂漿，以形成砂漿固化物。 The invention provides a method for manufacturing a cured mortar, which comprises the following steps: providing an alkaline solution, wherein the alkaline solution is composed of hydroxide and water; adding fly ash and fine particles to the alkaline solution and stirring to form Mortar; and cured mortar to form a cured mortar.
本發明提供一種砂漿固化物，其包括30~90wt%的細粒料以及10~70wt%的由上述的膠結材的製造方法製成的膠結材。 The present invention provides a mortar cured product, which includes 30 to 90 wt% of fine particles and 10 to 70 wt% of cement material made by the above cement material manufacturing method.
基於上述，在本發明的膠結材及砂漿固化物的製造方法中的作為鹼激發用途的鹼性溶液僅由氫氧化物及水組成，因此可使形成膠結材及砂漿固化物的製造成本降低。此外，本發明的膠結材及砂漿固化物的製造方法將飛灰作為原料之一，除了可將飛灰回收再利用外，亦可使處理飛灰所需的成本與形成膠結材及砂漿固化物的製造成本降低。並且，本發明藉由找出所使用的鹼性溶液的鹼當量、於鹼性溶液中加入飛灰的攪拌溫度以及膠結溶液經固化的溫度的最適範圍可使所形成之膠結材具有良好的抗壓強度。 Based on the above, in the method for producing a cemented material and a cured mortar of the present invention, the alkaline solution used for alkali excitation is composed only of hydroxide and water, and therefore, the manufacturing cost of forming the cemented material and the cured mortar can be reduced. In addition, the manufacturing method of the cement material and the mortar cured product of the present invention uses fly ash as one of the raw materials. In addition to recycling the fly ash, the cost required for processing the fly ash and forming the cement and mortar cured product Lower manufacturing costs. Moreover, the present invention can make the formed cement material have good resistance by finding out the alkali equivalent of the alkaline solution used, the stirring temperature of adding fly ash to the alkaline solution, and the optimum temperature range of the curing temperature of the cement solution Compressive strength.

圖1為本發明的一實施例的膠結材的製造方法的步驟流程圖。 FIG. 1 is a flowchart of steps of a method for manufacturing a cement material according to an embodiment of the invention.
請參照圖1，在步驟S100中，提供鹼性溶液。鹼性溶液例如是由氫氧化物及水組成。意即，在鹼性溶液中實質上不包括任何的矽酸鹽類。在此情況下，可使製成之後作為鹼激發用途的鹼性 溶液的成本降低。氫氧化物例如是氫氧化鈉、氫氧化鉀或其組合。 Referring to FIG. 1, in step S100, an alkaline solution is provided. The alkaline solution is composed of hydroxide and water, for example. This means that the alkaline solution does not substantially include any silicates. In this case, it can be made alkaline The cost of the solution is reduced. The hydroxide is, for example, sodium hydroxide, potassium hydroxide, or a combination thereof.
接著，在步驟S110中，在鹼性溶液中加入飛灰並攪拌，以形成膠結溶液。飛灰的來源可例如為由燃煤火力發電廠產生的F級飛灰，而其主要的組成例如由表1所示。從表1可看出，在飛灰中含有大量的SiO2、Al2O3、Fe2O3等酸性氧化物，因此，飛灰易於鹼性溶液中溶解出矽鋁酸鹽。當飛灰於鹼性溶液中溶解出矽鋁酸鹽時，鹼性溶液中的氫氧根離子會與矽鋁酸鹽進行“鹼激發反應”，以產生類似水泥漿體的膠結溶液。上述的“鹼激發反應”為藉由氫氧根離子解離矽鋁酸鹽的結構體，且經解離後的矽鋁酸鹽的結構體會再重新鍵結組構。飛灰的平均粒徑也影響其經溶解出的矽鋁酸鹽的多寡。飛灰的平均粒徑例如為<5μm。飛灰的平均粒徑在上述範圍內時，由於飛灰的細度足夠小而具有較大的活性，因此可提升進行“鹼激發反應”之反應速率，而使所形成之膠結材的抗壓強度高於習知膠結材的抗壓強度。 Next, in step S110, fly ash is added to the alkaline solution and stirred to form a cementing solution. The source of the fly ash may be, for example, Class F fly ash produced by coal-fired thermal power plants, and its main composition is shown in Table 1, for example. It can be seen from Table 1 that fly ash contains a large amount of acidic oxides such as SiO 2 , Al 2 O 3 , and Fe 2 O 3. Therefore, fly ash is easy to dissolve aluminosilicate in alkaline solution. When fly ash dissolves aluminosilicate in an alkaline solution, the hydroxide ions in the alkaline solution will undergo an "alkali excitation reaction" with the aluminosilicate to produce a cement paste-like cementing solution. The above “alkali excitation reaction” is to dissociate the aluminosilicate structure by hydroxide ions, and the dissociated aluminosilicate structure will be re-bonded to the structure. The average particle size of fly ash also affects the amount of dissolved aluminosilicate. The average particle size of fly ash is, for example, <5 μm. When the average particle size of the fly ash is within the above range, since the fineness of the fly ash is sufficiently small and has a large activity, the reaction rate of the "alkaline excitation reaction" can be increased, and the pressure resistance of the formed cement material can be increased. The strength is higher than the compressive strength of conventional cementitious materials.
鹼性溶液的鹼當量、於鹼性溶液中加入飛灰的攪拌溫度會影響形成膠結材所需的攪拌時間。一般來說，當鹼性溶液的鹼當量以及攪拌溫度越高時，則所需的攪拌時間越少，然而，鹼性溶液的鹼當量以及攪拌溫度皆有其的最適範圍。鹼性溶液的鹼當量例如為10%~20%，較佳為15%~20%，更佳為20%。若鹼性溶液的鹼當量低於10%時，飛灰經溶解出的矽鋁酸鹽過少，其會使往後所形成之膠結材的緻密性較低，而使所述膠結材的抗壓強度遠低於習知膠結材的抗壓強度。並且，若鹼性溶液的鹼當量高於20%時，飛灰經溶解出的矽鋁酸鹽雖然較多，然而其會影響鹼激發反應的速率，而使得所形成之膠結材的抗壓強度並不如想像中的高於習知膠結材的抗壓強度，且會使形成鹼性溶液的成本上升。於鹼性溶液中加入飛灰的攪拌溫度例如為25℃~95℃，較佳為60℃~90℃，更佳為90℃。當攪拌溫度低於25℃時，則進行“鹼激發反應”的時間將會過長，甚至無法進行“鹼激發反應”。當攪拌溫度高於95℃時，形成膠結材所需的攪拌時間雖然可大幅縮短，但膠結材的抗壓強度將由於不充足的反應時間而使得其抗壓強度較低。當鹼性溶液的鹼當量以及於鹼性溶液中加入飛灰的攪拌溫度皆處於上述範 圍時，形成膠結材所需的攪拌時間為30秒~300分鐘。 The alkali equivalent of the alkaline solution and the stirring temperature of adding fly ash to the alkaline solution will affect the stirring time required to form the cement. Generally speaking, the higher the alkali equivalent and stirring temperature of the alkaline solution, the less the stirring time required. However, the alkali equivalent and stirring temperature of the alkaline solution have their optimum ranges. The alkali equivalent of the alkaline solution is, for example, 10% to 20%, preferably 15% to 20%, and more preferably 20%. If the alkali equivalent of the alkaline solution is less than 10%, too little aluminosilicate dissolves out of the fly ash, which will cause the compactness of the cement material formed in the future to be low, and make the cement material pressure resistant The strength is much lower than the compressive strength of conventional cement materials. Moreover, if the alkali equivalent of the alkaline solution is higher than 20%, although there are more aluminosilicates dissolved in the fly ash, it will affect the rate of alkali excitation reaction and make the compressive strength of the formed cement material It is not as high as expected than the compressive strength of conventional cement materials, and will increase the cost of forming an alkaline solution. The stirring temperature for adding fly ash to the alkaline solution is, for example, 25°C to 95°C, preferably 60°C to 90°C, and more preferably 90°C. When the stirring temperature is lower than 25°C, the time for "alkaline excitation reaction" will be too long, and even the "alkali excitation reaction" cannot be performed. When the stirring temperature is higher than 95°C, although the stirring time required to form the cement material can be greatly shortened, the compressive strength of the cement material will be lower due to insufficient reaction time. When the alkali equivalent of the alkaline solution and the stirring temperature of adding fly ash to the alkaline solution are within the above range At the time, the stirring time required to form the cement material is 30 seconds to 300 minutes.
最後，在步驟S120中，固化膠結溶液，以形成膠結材。在膠結溶液經固化的過程中，膠結溶液逐漸失去可塑性而變成不具有流動性的狀態，之後膠結溶液的強度將雖著時間的推移而逐漸地增加，最後變成具有高抗壓強度的膠結材。膠結溶液經固化的溫度及時間具有相關性，舉例來說，當膠結溶液經固化的溫度越高時，則膠結溶液經固化的時間越短。膠結溶液經固化的溫度例如為60℃~80℃，且膠結溶液經固化的時間例如為12小時~96小時。膠結溶液經固化的溫度及時間處於上述範圍時可使所形成之膠結材具有高的抗壓強度。 Finally, in step S120, the cement solution is cured to form a cement material. During the curing process of the cementing solution, the cementing solution gradually loses its plasticity and becomes a state without fluidity. After that, the strength of the cementing solution will gradually increase despite the passage of time, and finally it will become a cementitious material with high compressive strength. The temperature and time of the curing of the cementing solution are related. For example, the higher the temperature of the cementing solution is cured, the shorter the curing time of the cementing solution. The curing temperature of the cement solution is, for example, 60° C. to 80° C., and the curing time of the cement solution is, for example, 12 hours to 96 hours. When the curing temperature and time of the cementing solution are within the above range, the cementitious material formed can have high compressive strength.
在本發明的膠結材的製造方法中的作為鹼激發用途的鹼性溶液僅由氫氧化物及水組成，換句話說，與習知的鹼性溶液相比其不包含任何矽酸鹽類，因此可使形成膠結材的製造成本降低。此外，本發明的膠結材的製造方法將飛灰作為原料之一，除了可將飛灰回收再利用外，亦可將由飛灰於鹼性溶液中溶解出的鋁矽酸鹽替代常用的鹼金屬矽酸鹽作為進行“鹼激發反應”時的反應物，藉此使處理飛灰所需的成本與形成膠結材的製造成本降低。 The alkaline solution used for alkali excitation in the manufacturing method of the cement material of the present invention consists only of hydroxide and water. In other words, it does not contain any silicates compared to the conventional alkaline solution. Therefore, the manufacturing cost of the cemented material can be reduced. In addition, the manufacturing method of the cement material of the present invention uses fly ash as one of the raw materials. In addition to recycling the fly ash, the aluminosilicate dissolved from the fly ash in an alkaline solution can also be used to replace the common alkali metal Silicate is used as a reactant during the "alkali excitation reaction", thereby reducing the cost required for the treatment of fly ash and the manufacturing cost of forming cement.
圖2為本發明的第一實施例的砂漿固化物的製造方法的步驟流程圖。 FIG. 2 is a flowchart of steps of the method for manufacturing a mortar cured product according to the first embodiment of the present invention.
請參照圖2，步驟S200與圖1所示的步驟S100相同，因此以下不再贅述。 Please refer to FIG. 2, step S200 is the same as step S100 shown in FIG. 1, so details are not described below.
請繼續參照圖2，在步驟S210中，在鹼性溶液中加入飛 灰及細粒料並攪拌，以形成砂漿。當於鹼性溶液中加入飛灰時，鹼性溶液中的氫氧根離子會與飛灰於其中溶解出的鋁矽酸鹽進行“鹼激發反應”，以於鹼性溶液中產生膠結體，而所述膠結體之後會與添加於鹼性溶液中的細粒料混合以形成砂漿。飛灰的來源及其平均粒徑的範圍已記述於上述膠結材的製造方法的實例中，因此不再贅述。細粒料例如是細砂、粒徑較小的石頭等，但不以此為限。細粒料的粒徑例如小於4.75mm。於鹼性溶液中加入飛灰及細粒料的攪拌時間例如為30秒~300分鐘。 Please continue to refer to FIG. 2, in step S210, add the fly in the alkaline solution Ash and fine particles and mix to form mortar. When fly ash is added to the alkaline solution, the hydroxide ions in the alkaline solution will undergo an “alkali excitation reaction” with the aluminosilicate dissolved in the fly ash to produce cement in the alkaline solution. The cement will then be mixed with the fine particles added in the alkaline solution to form a mortar. The source of the fly ash and the range of its average particle diameter have already been described in the above-mentioned example of the manufacturing method of the cement material, and therefore will not be described in detail. The fine particles are, for example, fine sand, stones with a small particle size, etc., but not limited to this. The particle size of the fine particles is, for example, less than 4.75 mm. The stirring time for adding fly ash and fine particles to the alkaline solution is, for example, 30 seconds to 300 minutes.
最後，在步驟S220中，固化砂漿，以形成砂漿固化物。在砂漿經固化的過程中，砂漿逐漸失去可塑性而變成不具有流動性的狀態，之後砂漿的強度將隨著時間的推移而逐漸地增加，最後變成具有高抗壓強度的砂漿固化物。砂漿經固化的溫度例如為60℃~80℃，且砂漿經固化的時間例如為12小時~96小時。砂漿溶液經固化的溫度及時間處於上述範圍時可使所形成之砂漿固化物具有高的抗壓強度。 Finally, in step S220, the mortar is cured to form a cured mortar. During the curing process of the mortar, the mortar gradually loses its plasticity and becomes a state of no fluidity. After that, the strength of the mortar will gradually increase with time, and finally become a mortar cured product with high compressive strength. The curing temperature of the mortar is, for example, 60°C to 80°C, and the curing time of the mortar is, for example, 12 hours to 96 hours. When the curing temperature and time of the mortar solution are within the above range, the formed mortar cured product can have high compressive strength.
本發明的砂漿固化物的製造方法由於與上述的膠結材的製造方法使用的鹼性溶液皆僅由氫氧化物及水組成，換句話說，與習知的鹼性溶液相比其不包含任何矽酸鹽類，因此可使形成砂漿固化物的製造成本降低。此外，本發明的砂漿固化物的製造方法將飛灰作為原料之一，除了可將飛灰回收再利用外，亦可將由飛灰於鹼性溶液中溶解出的鋁矽酸鹽替代常用的鹼金屬矽酸鹽作為進行“鹼激發反應”時的反應物，藉此使處理飛灰所需的成本與形成砂 漿固化物的製造成本降低。 The manufacturing method of the mortar cured product of the present invention is composed of hydroxide and water only as the alkaline solution used in the above-mentioned cement manufacturing method, in other words, it does not contain any more than the conventional alkaline solution. Silicates can reduce the manufacturing cost of forming mortar cured products. In addition, the method for manufacturing the cured mortar of the present invention uses fly ash as one of the raw materials. In addition to recycling the fly ash, the aluminosilicate dissolved from the fly ash in an alkaline solution can also be used to replace the common alkali Metal silicate is used as a reactant in the "alkali excitation reaction", thereby making the cost of processing fly ash and forming sand The manufacturing cost of the slurry cured product is reduced.
圖3示出本發明的膠結材的色澤與鹼性溶液的鹼當量以及於鹼性溶液中加入飛灰的攪拌溫度的關係。 Fig. 3 shows the relationship between the color of the cement material of the present invention and the alkali equivalent of the alkaline solution and the stirring temperature of the fly ash added to the alkaline solution.
請參照圖3，可看出膠結材的色澤深受鹼性溶液的鹼當量及攪拌溫度的影響。當鹼性溶液的鹼當量越高且攪拌溫度也越高時，則膠結材的色澤越深。 Please refer to Fig. 3, it can be seen that the color of the cement material is deeply affected by the alkali equivalent of the alkaline solution and the stirring temperature. When the alkali equivalent of the alkaline solution is higher and the stirring temperature is higher, the color of the cement material is darker.
圖4為本發明的膠結材的抗壓強度在所使用的鹼性溶液的鹼當量為5%、10%、15%、20%及25%的情況下與於鹼性溶液中加入飛灰的攪拌溫度的關係曲線圖。 Fig. 4 shows the compressive strength of the cement material of the present invention when the alkali equivalent of the alkaline solution used is 5%, 10%, 15%, 20% and 25%, and the addition of fly ash to the alkaline solution The graph of the relationship of stirring temperature.
請參照圖4，可看出膠結材的抗壓強度深受鹼當量以及攪拌溫度的影響。在固定攪拌溫度為60℃~90℃中的某個溫度的情況下，當使用的鹼性溶液的鹼當量為10%~20%時，膠結材的抗壓強度皆超過40MPa，意即，使用的鹼性溶液的鹼當量介於10%~20%時可使所形成之膠結材具有較佳的抗壓強度。此外，膠結材的抗壓強度會隨著攪拌溫度上升而上升，所屬領域具通常知識者可根據所需來選擇攪拌溫度。 Please refer to FIG. 4, it can be seen that the compressive strength of the cement material is deeply affected by the alkali equivalent and the stirring temperature. When the fixed stirring temperature is a certain temperature in the range of 60 ℃ ~ 90 ℃, when the alkali equivalent of the alkaline solution used is 10% ~ 20%, the compressive strength of the bonding material exceeds 40MPa, which means that When the alkali equivalent of the alkaline solution is between 10% and 20%, the cement material formed can have better compressive strength. In addition, the compressive strength of the cement material will increase with the rise of the stirring temperature. Those skilled in the art can choose the stirring temperature according to the needs.

請參照圖5，可看出攪拌時間深受攪拌溫度的影響。在攪拌溫度為60℃時，攪拌時間需為225分鐘可使膠結材具有其最大的抗壓強度(約65MPa)。然而，在攪拌溫度為90℃時，攪拌時 間則僅需15分鐘即可使膠結材具有其最大的抗壓強度(約66MPa)。另外，可看出膠結材在攪拌溫度為60℃、70℃、80℃及90℃的情況下，其各自可皆具有至少>55MPa的抗壓強度。 Please refer to FIG. 5, it can be seen that the stirring time is deeply affected by the stirring temperature. When the stirring temperature is 60°C, the stirring time needs to be 225 minutes to make the cement material have its maximum compressive strength (about 65MPa). However, when the stirring temperature is 90°C, when stirring It only takes 15 minutes to make the cement material have its maximum compressive strength (about 66MPa). In addition, it can be seen that when the stirring temperature is 60°C, 70°C, 80°C, and 90°C, each of them can have a compressive strength of at least >55 MPa.
圖6為本發明的膠結材的抗壓強度在膠結材的經固化溫度為60℃、70℃及80℃的情況下與膠結材的經固化時間的關係曲線圖。 6 is a graph showing the relationship between the compressive strength of the cement material of the present invention and the curing time of the cement material when the cement material has a cured temperature of 60°C, 70°C, and 80°C.
請參照圖6，可看出膠結材所需的固化時間深受其固化溫度的影響。當膠結材的經固化溫度為80℃時，膠結材僅需經過12小時的固化時間即可有一定的抗壓強度(約50MPa)，而在膠結材的經固化溫度為60℃時，膠結材則需經過48小時的固化時間即可有一定的抗壓強度(約31MPa)。此外，在固化時間為96小時下，由經歷固化溫度為60℃、70℃及80℃而各自形成的膠結材皆具有較高的抗壓強度(約45~60MPa)。另外，可看出膠結材在固化溫度為60℃、70℃及80℃的情況下，其各自可皆具有至少>45MPa的抗壓強度。 Please refer to FIG. 6, it can be seen that the curing time required for the cement material is deeply affected by its curing temperature. When the curing temperature of the cement material is 80℃, the cement material only has a certain compressive strength (about 50MPa) after 12 hours of curing time, and when the cement material's curing temperature is 60℃, the cement material It takes 48 hours of curing time to have a certain compressive strength (about 31MPa). In addition, at a curing time of 96 hours, each of the cement materials formed by the curing temperature of 60°C, 70°C and 80°C has a higher compressive strength (about 45~60MPa). In addition, it can be seen that when the curing temperature is 60°C, 70°C, and 80°C, each of them can have a compressive strength of at least >45 MPa.
綜上所述，在本發明的膠結材及砂漿固化物的製造方法中的作為鹼激發用途的鹼性溶液僅由氫氧化物及水組成，換句話說，與習知的鹼性溶液相比其不包含任何矽酸鹽類，因此可使形成膠結材及砂漿固化物的製造成本降低，並且其所形成之膠結材仍具有一定的抗壓強度。此外，本發明的膠結材及砂漿固化物的製造方法將飛灰作為形成膠結材的原料之一，除了可將飛灰回收再利用外，亦可將由飛灰於鹼性溶液中溶解出的鋁矽酸鹽替代常用的 鹼金屬矽酸鹽作為進行“鹼激發反應”時的反應物，藉此使處理飛灰所需的成本與形成膠結材及砂漿固化物的製造成本降低。 In summary, in the method of manufacturing the cementitious material and the mortar cured product of the present invention, the alkaline solution used for alkali excitation consists only of hydroxide and water, in other words, compared with the conventional alkaline solution It does not contain any silicates, so it can reduce the manufacturing cost of forming cementitious materials and mortar cured products, and the cementitious materials formed still have a certain compressive strength. In addition, the manufacturing method of the cement material and the mortar cured product of the present invention uses fly ash as one of the raw materials for forming the cement material. In addition to recycling the fly ash, it is also possible to dissolve the aluminum dissolved from the fly ash in the alkaline solution. Silicate replacement is commonly used Alkali metal silicate is used as a reactant when performing "alkali excitation reaction", thereby reducing the cost required for the treatment of fly ash and the manufacturing cost of forming a cement material and a mortar cured product.
並且，本發明藉由找出所使用的鹼性溶液的鹼當量、於鹼性溶液中加入飛灰的攪拌溫度以及膠結溶液經固化的溫度的最適範圍可使所形成之膠結材具有良好的抗壓強度。 Moreover, the present invention can make the formed cement material have good resistance by finding out the alkali equivalent of the alkaline solution used, the stirring temperature of adding fly ash to the alkaline solution, and the optimum temperature range of the curing temperature of the cement solution Compressive strength.
