Description
Technical field
The present invention relates to the gelling material field, be meant that specifically a kind of alkali excites composite gelled material and preparation method thereof.
Background technology
It is the one type of gelling material that is formed by pozzolanic activity or latent hydraulicity raw material and alkali-activator reaction that alkali excites gelling material, and the scope of hydraulicity mineral rubber gel material has been expanded in its invention.The FSU has carried out big quantity research in this respect, has developed alkali slag cement.Discover, compare that alkali slag cement has advantages such as water requirement is little, hydration heat is low, intensity is high, good endurance, but also have fatal shortcomings such as rate of set is fast, the sclerosis drying shrinkage is big, limited it and applied on a large scale with general purpose portland cement.The seventies in 20th century, French Davidovits is a main raw material with the metakaolin, develops novel alkali and excited the metakaolin gelling material, and with its called after geopolymer (geopolymer).Discover that geopolymer has many performances more excellent than silicate cement, demonstrates good prospects for application at aspects such as building, chemical industry, waste treatment.Because the metakaolin price is higher, adopts various industrial residues partly or entirely to replace metakaolin in recent years and prepare alkali and excite composite gelled material to become the focus of domestic and international research.
Literature search discloses: 1. Yip etc. is 2008; 30 (10): 979-985; Deliver the article of " Carbonate mineral addition to metakaolin-based geopolymers " on " Cement & Concrete Composites " publication; Be illustrated in the calcite or the rhombspar of adding about 20% in the metakaolin base geological polymer, can improve its ultimate compression strength, but can cause the bigger contraction of examination body appearance in initial 90d; 2. Zhu Qiang etc. is 2011; 39 (4): 690-696; Deliver the article of " mechanical property and the microtexture that contain rhombspar micro mist fly ash base geopolymer " on " silicate journal " publication; Show the rhombspar powder that mixes 10-25% help to improve geopolymer early stage with later stage ultimate compression strength, rhombspar is participated in reaction in geopolymer, the Ca of stripping, Mg combine the micro aggregate effect of good interface combination between the calcium magnesium alumino metasilicate gel, rhombspar-gel-in-matrix of the densification of formation and rhombspar micro mist with the geopolymer gel; Promote geopolymer strength development and raising jointly, but do not studied time of coagulation and shrinkage; 3. the patent of Chinese CN 1699250A and CN 1699251A; Through slag being carried out pre-treatment, adopting retardant bariumchloride or nitrate of baryta; Solve the alkali-activated-carbonate/slag composite gelled material and mix the caused fast problem of coagulating because of scoriaceous; But disclosed method technology is relatively complicated, and the duration is longer, is unfavorable for the engineering site construction operation.
The present invention's design is through adjustment water glass solution parameter; The mass ratio of slag, flyash, metakaolin, rhombspar or Wingdale; Give full play to the synergistic effect of each component; Thereby the alkali that prepare that technology is simple, time of coagulation and intensity can be regulated as requested excites composite gelled material, not only can be used as general building materials and uses, and also can be used for the slip casting backfill, solidify Toxic waste etc. to special occasions.
Summary of the invention
The objective of the invention is to: the alkali that provide that a kind of technology is simple, time of coagulation and intensity can be regulated as requested excites composite gelled material.
The objective of the invention is to realize like this: a kind of alkali-activated-carbonate composite gelled material and preparation method thereof
, modified water glass solution and the solid powder mass ratio by 0.6-1.0:1 is taken by weighing; Through preparing: under 60-120 rev/min stirring, solid powder is slowly joined in the modified water glass solution, continue to stir 3-5 minute, get product;
The wherein preparation of modified water glass solution: dissolution of sodium hydroxide in liquid sodium silicate, or is dissolved in sodium hydroxide in the tap water with sodium silicate solid, continues stirring and dissolving, transparent up to solution; The modulus of gained water glass solution is a silicon-dioxide and the ratio of the amount of substance of sodium oxide is 1.2-2.0, and silicon-dioxide and sodium oxide mass concentration sum are 25-45%;
Wherein solid powder is prepared with weight part: be made up of 15-30 part slag, 5-20 part flyash, 10-30 part metakaolin, 20-70 part ground dolomite or limestone powder: above-mentioned raw materials is placed mixer successively; Under normal temperature, normal pressure; With 60-120 rev/min; Stirred 5-15 minute, and got product;
Said method, gained alkali excites composite gelled material to test through national standard, and its degree of mobilization is 180-260mm, and be 3h-34h time of coagulation, and 3d ultimate compression strength reaches 16.6MPa, and 28d ultimate compression strength reaches 40.0MPa.
The alkali that the inventive method operating procedure is simple, time of coagulation and intensity can be regulated as requested excites composite gelled material, not only can be used as general building materials and uses, and the use of also can be used for the slip casting backfill, solidifying special occasions such as Toxic waste shows technical progress.
