What is advantages and dosage of powder polycarboxylate superplasticizer?

The polycarboxylate Superplasticizer powder PCE adopts a conventional-breaking production process, using a thermal synthesis method. This can reduce production costs in terms of energy consumption. It does not add a separating agent, resulting in a higher purity of the product. The solid content is controlled at around 98%. In terms of product performance, high-purity products have the characteristics of low dosage, high retention of active ingredients, and good stability. This further reduces the cost for customers.

The polycarboxylate Superplasticizer powder PCE has excellent dispersibility and fluidity for cement at low dosage; when the dosage is greater than 0.12% to 0.22%, the consistency of the paste shows a very significant increase; the loss of paste consistency within one hour decreases as the dosage increases.

The results of the water reduction rate of mortar have a corresponding relationship with the results of the fluidity of the pure paste. That is, the greater the fluidity of the pure paste, the greater the water reduction rate of the mortar. As the dosage increases, the water reduction rate increases rapidly, and it is relatively high. The water reduction rate of concrete with the water reducer is often inconsistent with the water reduction rate of the mortar due to the influence of the properties of the admixture and the sand and stone. When the properties of the admixture and the sand and stone are conducive to the fluidity of the concrete, the water reduction rate of the concrete is higher than that of the mortar, and vice versa.

The recommended dosage of polycarboxylate Superplasticizer powder PCE is: 0.1% to 0.3% of the cement usage. The powder type polycarboxylate Superplasticizer powder PCE water reducer is a powder mainly composed of polycarboxylate salts, with a solid content of about 98%. The normal dosage is 0.1% to 0.3%, and when the dosage is only 0.06%, it can achieve a 12% water reduction rate and a 23% strength increase, which is better than that of ordinary pumping agents. When the dosage is 0.1%, its performance exceeds that of common naphthalene-based and pyrimidine-based high-efficiency water reducers. However, when the dosage is lower than 0.14%, the excellent performance of the workability is not obvious. When the dosage reaches 0.20% or above, the workability and pumping performance of the concrete improve to an excellent level. When configuring high-grade, large-concentration fly ash/slag micro-powder concrete and concrete with special requirements, the dosage can be increased to 0.3%.

Technical performance advantages of Polycarboxylate Superplasticizer powder PCE:

(1) Low dosage, high water reduction rate;
