To determine the effect of direct embedment of Bacillus megaterium into Portland pozzolana cement mortars on water sorptivity and diffusivity coefficient of sulphate ions. Prisms with a water/cement ratio of 0·5 were prepared by blending Portland Pozzolana cement with the requisite volume of a B. megaterium (microbial) solution whose concentration was 1·0×10 cells per ml. Mortar prisms of 160mm×40mm×40mm were fabricated for this study. Mortars cured for 28days were exposed to 0·2465moll Na SO solution using accelerated ion migration
