Cement slurry additives are specialized compounds designed to enhance the performance and properties of cement slurries used in various construction and engineering applications. Due to low water gel, drying, cracking and deformation is usually happen. SINOFLOC superabsorbent polymers is specially designed to control the shrinkage of concrete and improve the moisture content of concrete to be used as cement additives. After adding SINOFLOC superabsorbent, it can absorb dozens of its own weight of water and release slowly, which could prevent concrete cracking and increase the concrete strength. This application could improve concrete's performance of impermeability and properties in cold weather significantly.
