Water and reactive agent CS-21 concrete modifier
A safe and comfortable future for concrete structures and people.
CS-21 is a chemical agent that has catalytic properties to activate and promote the hydration reaction of cement. Cement concrete inherently has the ability to transform into a dense and strong material over a long period when cured in water. Additionally, if cracks occur, it has the property to fill those cracks through the hydration reaction of cement. This is because even in concrete that has been placed for several decades, unhydrated cement still exists. However, in the case of current concrete structures, the generation of cement crystals through the hydration reaction takes time, and the conditions necessary for the hydration reaction do not persist, leading to deterioration. When CS-21 is sprayed or applied to hardened concrete and water curing is performed after hardening, unhydrated cement and unstable hydration products are rapidly transformed into more stable CSH-type crystals, filling the voids. This reaction will continue for a long time as long as moisture and unhydrated cement are present.
