Fly ash


 

The use of fly ash as an addition to concrete is widely used for two reasons: the economic savings from the reduction of the cement used and the microstructural changes caused by the addition.
On this second point, there is consensus in considering that fly ash generates a more compact concrete and a reduction in the average pore size.
Properly used, fly ash is an active addition that can improve the durable and mechanical properties of concrete in most cases.

Dolomite


 

La dolomita, denominada de esa forma en honor al geólogo francés déodat gratet de dolomieu, es un mineral compuesto decarbonato de calcio y magnesio. se emplea como árido de hormigón siempre que se
