1. Product Introduction
This product is made of retarding, plastic-preserving, foam-reducing and water-reducing components. Under high temperature conditions in summer, it can delay the setting time of concrete and make new Mixed concrete maintains its plasticity for a longer period of time to facilitate pouring and molding. When applied to fluid concrete, it can increase the cohesion of concrete, reduce slump loss and segregated bleeding. In the continuous pouring of large volumes of concrete, it can reduce the heat of hydration, delay the peak of hydration heat release, and reduce temperature cracks. The production of admixture is an indispensable type of admixture in summer concrete construction.
