Early-strength high-efficiency water-reducing admixture is an admixture with both early-strength and significant water-reducing functions. Under the condition of ensuring that the concrete drop rate and cement dosage remain unchanged, the dosage is cement quality and has a higher Admixtures that reduce water and increase the strength of concrete can reduce water consumption, thereby significantly improving the physical and mechanical properties of concrete. Early-strength high-efficiency water-reducing admixture is a low-air-entraining admixture. The air content of concrete can significantly improve the water retention and cohesion of concrete. It has a significant plasticizing function and can increase the early strength by about 30%. It has a certain promotion effect. Hard and bleed function.
Early-strength high-efficiency water-reducing admixture accelerates setting more obviously. The initial setting and final setting are about 1 hour in advance. Concrete mixed with early-strength high-efficiency water-reducing admixture is resistant to frost damage, freeze-thaw resistance, permeability, and wear resistance. Other properties are significantly improved. The early-strength high-efficiency water-reducing agent has good adaptability to slag cement, fly ash cement, and ordinary Portland cement. It has no obvious effect on the shrinkage of concrete, has no rust hazard to steel bars, and can improve the reinforcement of concrete. performance.
Early-strength high-efficiency water-reducing admixture is suitable for winter construction of concrete when the minimum temperature is not lower than -10℃. It can prevent freezing damage and speed up the construction progress: it is suitable for steam-cured concrete and normal temperature that require both early strength and Concrete that requires high strength, impermeability, freeze-thaw resistance, and dam drop. </p
