Compressive Strength Though addition of grinding aids is basically for the improvement in grinding efficiency it is observed that grinding aids can enhance the compressive strength of cement.
Concrete doesn't "dry", it cures. The added water does not evaporate out of the cement, it undergoes various chemical reactions to bind with the cement. In a sense the H2O remains in the cement. So grinding the cement doesn't reverse the curing process like it does for a mud brick, to undo the curing you'd have to break the chemical bonds that formed.
Grind Seal is an easy and economical way to transform any concrete floor. Grind and seal the natural gray for a modern, contemporary look, or add color to brighten up space. The use of different sealers can achieve anything from a matte, natural looking finish to a rich, highgloss finish.
