Through the analysis of the mechanism of superplasticizer, polycarboxylate liquor, the choice of a polar group containing -COO -, - SO3- acrylic acrylamide-2-methyl propane sulfonic acid, and containing a non-polar group - OH, -CH2CH20- polyethylene glycol monoacrylate as a reactive monomer, in an aqueous solution by Michael force H to be grafted onto the molecules containing NH2 was prepared with a three-dimensional configuration space hyperbranched or branches like macromolecules plasticizer. Polycarboxylate superplasticizer Features low ash and high performance polycarboxylate superplasticizer dispersion and reducing water of unique, although smaller in adsorption surface of cement particles, Taiwan polycarboxylic acid liquor, However, due to their having many branches, may produce steric hindrance, Hainan polycarboxylate mother liquor, and thus can achieve better content came from a plasticizing effect. Calculated in accordance with the volume, content is generally 0.1% to 0.3%, the content of the reducing agent and water reduction of about 0.6% -0.9% of naphthalene superplasticizer water reduction fairly. Content is 0.2% to 0.3% amount of cementitious material (active ingredient), the water rates of up to 25% to 35%, some up to 40%. Polycarboxylate in the case of a small amount of high water reduction can be achieved and good mobility, hardened concrete specimens look very dense and smooth, large pores less evenly distributed small bubbles, in favor of concrete Antifreeze integration impermeability durability, concrete performance test showed that the concrete mixed with early strong polycarboxylate admixtures low, Yunnan poly-carboxylic acid liquor, but later the strength of better than naphthalene superplasticizer strength development, with the latter part of high strength characteristics . And with the use of fly ash and mineral powder, Polycarboxylate more conducive to reducing the amount of cement as well as admixtures increase the amount within a certain range, with the increase of intensity also increased the amount of slag! Hunan liquor polycarboxylate, polycarboxylic acid liquor, high strength provided by the Linyi City Building Materials Co., high-strength construction materials.
