Polycarboxylic acid superplasticizer is the third generation of high-performance superplasticizer developed after common superplasticizer represented by wood calcium and superplasticizer represented by naphthalene series. The liquid is light yellow or brownish red transparent liquid. The main component is a series of polycarboxylic acid polymer products with a molecular weight of 5000-50000.
It is a series of water-reducing agents with excellent performance that integrates water reduction, slump retention, reinforcement, anti-shrinkage and environmental protection. It can solve the weaknesses of high-strength, high-performance concrete with high viscosity and poor construction performance. It is used to prepare high-strength, Ideal admixture for high performance concrete.
The blending amount of the polycarboxylic acid superplasticizer is 0.4% to 2.5% of the total weight of the gelling material, and the usual blending amount is 0.8% to 1.5%. Before use, a trial test of concrete should be carried out to obtain the best admixture.
Polycarboxylic acid superplasticizer cannot be mixed with naphthalene-based superplasticizer. When using polycarboxylic acid superplasticizer, the mixer and mixer that used naphthalene-based superplasticizer must be cleaned or the water reduction may be lost. effect.
When using polycarboxylic acid superplasticizer, it can be added directly in the form of the original solution, or it can be formulated into a solution with a certain concentration.
