Description
Technical field
The invention belongs to technical field of concrete additives, relate in particular to a kind of concrete intensifier and its preparation method and application.
Background technology
Concrete is human maximum ancestor's building structural materials, and it is through the simple and mechanical composite system forming that mixes and stirs by gelling material (cement, flyash, breeze etc.), aggregate (comprising sand, stone etc.) and liquid medium (water, admixture etc.).Concrete is also the heterogeneous composite system of a kind of complexity, the interfacial transition zone between homophase is not to affect concrete over-all properties greatest factor, and concrete many quality problems (as undercapacity, crack etc.) are all interfacial transition zone defectiveness and producing after all.Although ready mixed concrete has obtained significant progress, high cement consumption, high water usage amount, this " three height " phenomenon of high water-cement ratio still do not have material alterations.Along with the use of continuous progress, the especially admixture of science and technology, make concrete in performance, obtain significant raising, on cost, there is obvious reduction; But in order to ensure concrete serviceability, with the effect of current admixture, in concrete, also have all the time the cement of 20% left and right there is no abundant hydration reaction, thereby cannot further improve concrete intensity.
For this present situation, various countries experts and scholars have done a large amount of scientific researches aspect concrete intensifier, but do not obtain all the time obvious progress; Succeeding in developing of the 10 years up to date tensio-active agents due to new small molecule, just makes the research and development of concrete intensifier product obtain substantive breakthroughs.
Concrete intensifier is in mixing concrete process, to add together with concrete admixture, in order to improve concrete crushing strength, thereby reaches the object that reduces gel material content, saves concrete production cost.
CN102838315A Chinese patent literature discloses a kind of concrete intensifier, it is made up of the polyacrylamide copolymer aqueous solution and Synergist S-421 95, the mass ratio that the polyacrylamide copolymer aqueous solution accounts for toughener is 80%～95%, and the mass ratio that Synergist S-421 95 accounts for toughener is 5%～20%; Synergist S-421 95 is made up of colloid silica, tri-isopropanolamine, tripoly phosphate sodium STPP and trolamine, wherein to account for the weight ratio of described toughener be 1%～5% to colloid silica, the weight ratio that tri-isopropanolamine accounts for toughener is 0.5%～3%, the weight ratio that tripoly phosphate sodium STPP accounts for toughener is 0.1%～5%, and the weight ratio that trolamine accounts for toughener is 0.1%～3%; The pH value 8～10 of toughener.Its compound method is: first by Synergist S-421 95 raw material in proportion water be mixed with Synergist S-421 95 solution; Then under agitation in the polyacrylamide copolymer aqueous solution, add Synergist S-421 95 solution, add rear continuation and stir more than 10 minutes, make concrete intensifier.
CN101397199A Chinese patent literature discloses a kind of cement grinding aid reinforcing agent, and it is formulated by 1: 1.2～1.6: 0.1～0.5: 0.01～0.04 mass ratio by alcamines, polyalcohols, amides, initiator etc.Hydramine and polyvalent alcohol mix in retort, stir the lower reaction acidity of controlling, in 100 DEG C～110 DEG C reaction 2～6h; Add acid amides and initiator, adjusting pH value is 7～7.5, then stirring reaction 3～5h; Be neutralized to pH8～10 through alkali and obtain finished product.
From existing disclosed lot of documents, mainly there is following defect: 1) more for plain cement production process of existing toughener product, special relatively less for the toughener product of coagulation great soil group, but the material composition of cement and concrete and performance difference are larger, if cement class toughener is directly indiscriminately imitated in concrete, can there is very large change in effect often, is difficult to reach the enhancing object of expection; 2) existing coagulation great soil group toughener and current concrete production admixture adaptability used is not strong, and some tougheners adapt to naphthalene water reducer, but poly carboxylic acid and aliphatic water reducing agent are not almost had to effect; 3) existing part coagulation great soil group toughener product is not only prepared difficulty, and cost is high, and the improvement of concrete performance is need to further raising; 4) existing part coagulation great soil group toughener products material obtains difficulty, and the product feature of environmental protection is poor, easily causes environmental pollution, and the theory of this and green building runs in the opposite direction; 5) in addition, existing part concrete intensifier contains a certain amount of inorganic salt, and concrete weather resistance is existed to certain risk, and limited to late strength of concrete enhancement rate.
Therefore, how formula, raw material and the preparation technology to existing concrete toughener improves, and is the technical barrier that those skilled in the art face for a long time always.
Summary of the invention
