With the rapid development of the ready-mixed concrete industry, the progress and innovation of concrete has been accelerated, and new technical challenges have also been encountered: *Good stability and pumpability, speed up the construction speed of the project. *Excellent slump retention performance to avoid illegal operations on site. * The wide adaptability of raw materials reduces the pressure on quality control in concrete production. *Optimize concrete mix ratio, reduce energy consumption, and benefit environmental protection. Faced with these challenges, as a pioneer of concrete admixtures and a maintainer of industry quality, our unit is committed to the development and production of targeted high-quality products as the development direction, and has successfully developed innovative products that fully meet the low and medium strength levels.” SJ-53" type concrete pumping agent product.
