This research was carried out to evaluate the relationship between the incorporation of calcite precipitation bacteria, sporosarcina pasteurii using calcium lactate as nutrient source and the properties of calcined clay and limestone powder blended self-compacting concrete. Ten mixes were designed and designated S0 to S9 with S0 the control (without bacteria and nutrient) and S1 to S9 at varying bacteria and calcium lactate concentrations and the effect of the bacteria cell density and calcium lactate concentration on the compressive strength, sorptivity and tensile strength with age evaluated using experimental program and statistical packages (ANOVA and post hoc tests). The result of both the experimental program and statistical evaluation shows that the incorporation of sporosarcina pasteurii and calcium lactate as nutrient had a positive impact on the properties of the ternary blended self-compacting concrete.
