“Cement Anti-Permeation Admixture CK-NS96MT” is hydrophobic powder made from nano silica containing hydroxyl processed through organosilicon surface modification. The Si-O bond between nanosilica and organosilicon forms a reticular structure as the hydrophobic surface on lotus leaf and improve the problem of high water absorption of hydrophilic nano-silica. Apply CK-NS96MT, compatible to many kinds of water reducing agents, in concrete batch as an anti-permeation admixture, and it can optimize concrete structure to obtain improvements including impermeability, frost resistance, compression-resistance, durability, and setting retardation. Overall, it extends the lifespan by folds of the traditional cement materials.
Used as anti-permeation admixture in cement and concrete.
