Concrete Additives | Esteem Industries Pvt. Ltd.

Used in formulating cement retarders. The higher thermal stability of H-Quest™ C 100 allows formulated cement retarders to be stable above 200ºC (400ºF). Additionally, it produces a permanent increase in the cement volume, increased compressive strength, increased plasticity, and inhibits corrosion of the metal used in reinforced concrete.
