FLY ASH CONCRETE - WHAT ARE THE REASONS FOR ADDING FLY ASH

Fly ash chemically reacts with this lime to create more CSH, the same "glue" produced by the hydration of cement and water. By producing more CSH the paste becomes stronger over time and also closes off more of the capillaries that allow the movement of moisture through the concrete. The result is a stronger, more durable concrete that is less permeable, which aids in the reduction of ...
