Description
技术领域technical field
本发明属建筑材料技术领域，具体涉及一种水泥基桥面裂缝修补材料。The invention belongs to the technical field of building materials, and in particular relates to a cement-based bridge deck crack repairing material.
背景技术Background technique
桥面属于大尺寸薄板混凝土结构，桥面混凝土浇注施工后，如果不注意养护，极易产生塑性开裂现象，使用过程中也会因各种原因导致开裂。混凝土桥面内部大都配制一定比例的钢筋，裂缝的存在将使内部钢筋很快锈蚀，产生膨胀，导致裂缝进一步扩展。另外，由于裂缝的存在，不仅雨水、冷凝水容易渗入，而且更可怕的是，外界侵蚀性介质，如酸、碱、盐都会随着液、汽渗入桥面混凝土内部，导致产生化学侵蚀，桥面混凝土强度和承载力降低，体积稳定性变差。有时充水的桥面混凝土受到冻融循环破坏后，会引起裂缝进一步扩大，甚至结构整体胀裂。这些后果对混凝土桥面承载力和寿命的影响是非常大的。然而过去没有混凝土桥面专用修补材料，当桥面混凝土破坏达一定程度，不能继续服役时，往往要停止交通，对整个桥面板进行更换，这不仅严重限制了交通通行，而且经济代价很高。The bridge deck is a large-scale thin-slab concrete structure. After the bridge deck concrete is poured and constructed, if maintenance is not taken care of, plastic cracking will easily occur, and cracking will also occur due to various reasons during use. Most of the interior of the concrete bridge deck is equipped with a certain proportion of steel bars. The existence of cracks will cause the internal steel bars to corrode quickly and cause expansion, resulting in further crack expansion. In addition, due to the existence of cracks, not only rainwater and condensed water are easy to infiltrate, but what is even more frightening is that external corrosive media, such as acids, alkalis, and salts, will penetrate into the bridge deck concrete along with liquid and steam, resulting in chemical erosion. The strength and bearing capacity of the surface concrete are reduced, and the volume stability is deteriorated. Sometimes the water-filled bridge deck concrete is damaged by the freeze-thaw cycle, which will cause the cracks to expand further, and even the whole structure will burst. These consequences have a great impact on the bearing capacity and life of concrete bridge decks. However, in the past, there were no special repair materials for concrete bridge decks. When the bridge deck concrete was damaged to a certain extent and could not continue to serve, traffic was often stopped and the entire bridge deck was replaced. This not only severely restricted traffic, but also cost a lot of money.
目前，上海乃至全国的桥梁建设正迎来飞速增长的局面，而旧桥面的严重损坏和修复问题正摆在人们面前。因此，研制发明能有效修补桥面裂缝，且粘结性、耐磨性均十分理想的桥面裂缝专用修补材料，对改善桥面使用性能和延长桥面寿命，显得尤为必要。At present, bridge construction in Shanghai and even the whole country is ushering in a situation of rapid growth, and the serious damage and repair of old bridge decks are facing people. Therefore, it is particularly necessary to develop a special repair material for bridge deck cracks that can effectively repair bridge deck cracks, and has ideal cohesiveness and wear resistance.
发明内容Contents of the invention
本发明的目的在于提供一种能有效对桥面混凝土裂缝进行修补的水泥基桥面裂缝修补材料。The object of the present invention is to provide a cement-based bridge deck crack repairing material which can effectively repair bridge deck concrete cracks.

本发明中，硅酸盐系列水泥为硅酸盐水泥、普通硅酸盐水泥、矿渣水泥、火山灰水泥、粉煤灰水泥和复合水泥中的一种。In the present invention, the Portland series cement is one of Portland cement, ordinary Portland cement, slag cement, pozzolan cement, fly ash cement and composite cement.
本发明中，减水剂为萘磺酸甲醛缩合物高效减水剂，氨基磺酸盐高效减水剂，三聚氰胺高效减水剂，聚羧酸盐高效减水剂之一种。In the present invention, the water reducer is one of naphthalenesulfonic acid formaldehyde condensate superplasticizer, sulfamate superplasticizer, melamine superplasticizer and polycarboxylate superplasticizer.
本发明的制备方法是：按前述各重量比例称量各组份，将八种原料通过物理机械混合，搅拌均匀，即得到本产品。The preparation method of the present invention is as follows: weighing each component according to the aforementioned weight ratios, mixing eight kinds of raw materials through physical machinery, and stirring evenly to obtain the product.
本发明中硅酸盐系列水泥作为无机胶凝材料，加水拌合后，发生水化反应，产生水化产物，硬化后产生强度，并能与桥面混凝土和裂缝壁粘结起来，形成整体。高铝水泥加水拌合后，能很快发生水化反应，并促使修补材料短时间内凝结硬化和建立强度。纤维素作为保水增稠组份，其作用在于能在水泥浆体中溶胀，产生桥连作用，并通过分子吸附作用将水泥颗粒和石英砂、聚丙烯纤维连接在一起，避免颗粒沉降；在浆体流动时，保证浆体成为整体，并不产生泌水现象；纤维素的作用还在于防止浆体中水分被裂缝壁和桥面混凝土基层吸收或过度蒸发，从而起到良好的自养护作用。聚醋酸乙烯酯乳胶粉遇水后成为乳液，不仅能增加浆体的稳定性，而且浆体硬化过程中，乳液逐渐干燥失水，聚醋酸乙烯酯分子相互连接，形成一层高分子膜层，增强硬化浆体的韧性和抗冲击性。减水剂对水泥浆体具有分散作用，可以增强浆体的流动性，使浆体较顺利地渗入细微裂缝，达到有效的裂缝修补目的。硫铝酸盐膨胀剂参与水泥的水化，产生膨胀产物，膨胀产物的形成和膨胀可以补偿材料产生的体积收缩，使材料体积稳定。聚丙烯纤维分散在修补材料内部，大幅度提高修补材料的抗折强度，改善韧性、抗冲击性和耐磨性。石英砂的作用在于紧密堆积后为修补材料提供刚性骨架，水泥浆体填充在此刚性骨架中，并将其粘结硬化成为一个高强的整体。In the present invention, the Portland series cement is used as the inorganic gelling material. After mixing with water, a hydration reaction occurs to produce hydration products, which develop strength after hardening, and can be bonded with bridge deck concrete and crack walls to form a whole. After the high-alumina cement is mixed with water, the hydration reaction can quickly occur, and the repair material can be hardened and strengthened in a short time. As a water-retaining and thickening component, cellulose can swell in the cement slurry to produce a bridging effect, and connect the cement particles with quartz sand and polypropylene fibers through molecular adsorption to avoid particle settlement; When the slurry flows, it ensures that the slurry becomes a whole without bleeding; the role of cellulose is to prevent the water in the slurry from being absorbed or evaporated excessively by the crack wall and the concrete base of the bridge deck, so as to play a good self-curing effect. Polyvinyl acetate latex powder becomes an emulsion when it meets water, which not only increases the stability of the slurry, but also gradually dries and loses water during the hardening process of the slurry, and the polyvinyl acetate molecules are connected to each other to form a polymer film layer. Enhances toughness and impact resistance of hardened paste. The water reducing agent has a dispersing effect on the cement paste, which can enhance the fluidity of the paste, so that the paste can penetrate into the fine cracks more smoothly, and achieve the purpose of effective crack repair. The sulfoaluminate expansion agent participates in the hydration of cement and produces expansion products. The formation and expansion of expansion products can compensate for the volume shrinkage of the material and stabilize the volume of the material. Polypropylene fibers are dispersed inside the repair material, greatly increasing the flexural strength of the repair material, improving toughness, impact resistance and abrasion resistance. The role of quartz sand is to provide a rigid framework for the repair material after being closely packed. The cement paste fills this rigid framework and bonds and hardens it into a high-strength whole.
本发明为灰色干粉粒状物质，使用时，适宜的加水量为干粉粒状材料重量的12％-45％，具体加水量根据使修补材料达到所需的流动性通过试验确定。The present invention is a gray dry powder granular material. When used, the suitable amount of water added is 12%-45% of the weight of the dry powder granular material. The specific amount of water added is determined through experiments according to the required fluidity of the repair material.
本发明对混凝土内部钢筋无锈蚀作用，广泛适用于混凝土桥面的裂缝修补。The invention has no corrosion effect on the steel bars inside the concrete, and is widely applicable to the repair of cracks on concrete bridge decks.
本发明作为混凝土桥面裂缝修补材料使用，可有效渗入混凝土裂缝内部，并修补混凝土桥面，具有优异的流动性和保水性，凝结硬化速度快，产品硬化后与裂纹两壁和桥面混凝土基层的粘接强度高，具有较好的补偿收缩性、韧性、抗冲击性和耐磨性，耐高温和耐冻融循环能力强，耐久性优异。本发明使用方便，保水性、流动性极佳，凝结硬化和强度发展速度快，与裂缝和桥面混凝土粘结强度高，耐高温、耐冻融循环性都很好，且具有一定微膨胀性、抗冲击性，耐磨性优异。The invention is used as a repairing material for concrete bridge deck cracks, which can effectively penetrate into the concrete cracks and repair the concrete bridge deck.
