PCE Powder Polycarboxylate Superplasticizer Concrete Admixtures HS CODE 3824401000

PCE Monomer PCE Powder Polycarboxylate Superplasticizer is a high-performance water reducer, a cement dispersant used in cement/ concrete; it is the third generation of high-performance water reducers developed after the first generation of ordinary water reducers represented by wood calcium and the second generation of high-efficiency water reducers represented by naphthalene and aliphatic.

Compared with traditional high-efficiency water reducers such as naphthalene, polycarboxylate high-performance water reducers have many unique technical performance advantages. Therefore, PCE Monomer PCE Powder Polycarboxylate Superplasticizer polycarboxylate high-performance water reducers have begun to attract widespread attention in the domestic engineering community in recent years.

Many important projects have used this new type of water reducer in large quantities, such as Shanghai Maglev, Shanghai World Financial Center, Hangzhou Bay Cross-sea Bridge, Donghai Bridge, Beijing Yintai Building, Beijing Capital International Airport Expansion Project, etc. It can be foreseen that due to the above-mentioned unique performance advantages, polyacid high-performance water reducers will quickly become the mainstream product in the water reducer market.

PCE Monomer PCE Powder Polycarboxylate Superplasticizer is a new generation of environmentally friendly mortar-specific high-efficiency water reducer based on new synthetic technology. Its main component is polycarboxylate, and it is a fluid powder made by special drying technology. It has excellent comprehensive indicators, is green and pollution-free, and is a high-performance environmentally friendly product. The main features of this product are: good dispersibility, high water reduction rate, and good adaptability to various cements. This product is easy to transport and store. This product meets the national standard GB8076-2008 high-performance water reducer indicators.

PCE Monomer PCE Powder Polycarboxylate Superplasticizer has low dosage and high water reduction rate; it maintains the fluidity of the concrete mixture well; it has good compatibility with cement; the shrinkage rate of the prepared concrete is small, which is beneficial to improving the volume stability and durability of the concrete; production It is environmentally friendly, pollution-free, non-toxic, and non-corrosive during use, and is a green additive.

PCE Monomer PCE Powder Polycarboxylate Superplasticizer has high fineness, excellent dispersion, low gas content, and good adaptability to various cements, which can significantly improve the fluidity of mortar; it can increase the fluidity of grouting materials or cement mortars, improve work efficiency, and improve plasticity retention. Ability to increase early and late strength and prevent or reduce shrinkage and cracking of mortar after hardening.

PCE Monomer PCE Powder Polycarboxylate Superplasticizer is mainly used for cement sculpture craft components, dry mortar, high-strength mortar, self-leveling floor, tile adhesive, caulking agent, gypsum products, colored wear-resistant concrete floor caulking material, grouting material, non-shrinkage grouting material, mechanical grouting material, refractory floor mortar, self-leveling mortar, caulking material dry mix coagulation,gypsum ceramic sculpture products, waterproof mortar, repair mortar, insulation mortar cement-based bui lding premixed mortar, cement-based floor mortar, etc.

PCE Monomer PCE Powder Polycarboxylate Superplasticizer is also suitable for ordinary concrete, high-flow concrete, high-durability concrete, aluminate cement refractory concrete, low-cement refractory castable, steam-cured concrete, self-leveling concrete. The early strength and impermeability of concrete are significantly increased, and the construction and water retention are better, and there is no efflorescence. This product meets the high-performance water reducer index of GB8076-2008 national standard.

The recommended dosage of water reducer for concrete is: 0.1~0.3% of the amount of cementitious material.

PCE Monomer PCE Powder Polycarboxylate Superplasticizer with polycarboxylate as the main component, with a solid content of about 98%. The normal dosage is 0.1%-0.3%. When the dosage is only 0.06%, it has a water reduction rate of 12% and a strength increase of 23%, which has exceeded the effect of ordinary pumping agents on the market. When the dosage is 0.1%, the performance exceeds the level of general and pyrimidine high-efficiency water reducers. However, when the dosage is less than 0.14%, the excellent performance of the working performance is not obvious. When the dosage reaches more than 0.20%, the working performance and pumping performance of concrete are improved to a very excellent level. Therefore, the recommended optimal dosage is 0.12-0.24%; when configuring high-grade, large-volume fly ash/slag powder concrete and concrete with special requirements, the dosage can be increased to more than 0.3%, but generally should not exceed 0.5%. Experiments show that when the dosage is increased to 0.5%, the concrete does not produce cohesion and aggregate paste separation (segregation) phenomenon, and the water reduction rate still increases, but the air content increases, the setting is delayed, and the strength decreases.
