Pozzolan

Pozzolana generally improve paste cohesiveness, thus reducing segregation. This may be ascribed to the residual negative charge on the surfaces of aluminosilicate pozzolana leading to their better dispersion. This can also help to explain the improved workability seen in cement–pozzolan blends. However, a greater factor here is particle shape.
