Basic residential properties and system of action of potassium silicate

Potassium silicate is a water-soluble silicate whose aqueous solution is alkaline (pH 11-13). From the point of view of molecular framework, the SiO ₄ TWO ⁻ ions in potassium silicate can react with the cement hydration item Ca(OH)two to produce additional C-S-H gel, which is the chemical basis for improving the performance of concrete. In regards to mechanism of action, potassium silicate functions mainly with three methods: initially, it can increase the hydration reaction of cement clinker minerals (specifically C ₃ S) and promote early stamina growth; second, the C-S-H gel produced by the reaction can efficiently load the capillary pores inside the concrete and improve the density; ultimately, its alkaline qualities aid to reduce the effects of the erosion of carbon dioxide and postpone the carbonization process of concrete. These characteristics make potassium silicate a perfect selection for boosting the thorough efficiency of concrete.

Engineering application techniques of potassium silicate
