This research was performed to investigate the optimum conditions for developing pozzolanic ashes from organic wastes to be used as cement replacement materials. The organic wastes explored in the research are rice husk ash (RHA), wheat straw ash (WSA), and cow dung (CDA). When the organic waste is turned into ash, it develops a pozzolanic character due to the presence of silica.

Cement pastes prepared at w/c=0.4 with 100% white portland cement (WPC) and a 90:10 blend of white portland cement and VCAS pozzolan GP6 gave TB-1C values of 62.3 and 70.1, respectively. Thus, the VCAS pozzolans have a color/brightness that is somewhat whiter and brighter than white portland cement itself.
