Ultratech Cement

Description

Portland pozzolana cement is ordinary portland cement blended with pozzolanic materials (power-station fly ash, burnt clays, ash from burnt plant material or silicious earth), either together or separately. Portland clinker is ground with gypsum and pozzolanic materials which, though they do not have cementing properties in themselves, they combine chemically with portland cement in the presence of water to form extra strong cementing material, which resists wet cracking, thermal cracking and has a high degree of cohesion and workability in concrete and mortar.
