Accelerating cement hydration with C S H seeds

The acceleration of cement hydration through synthetic C S H shows great potential in increasing the early strength of cementitious systems The selection of a suitable calcium to silicon ratio and optimized synthesis conditions results in a significant strength gain compared to non optimized systems Polymers may contribute during synthesis to stabilizing the C S H aggregates thus enhancing
