The domain of enhancing the strength of supplementary cementitious materials (SCM) has not been extensively researched. Hence, biocementation involving the utilization of microorganisms or direct urease enzyme in such materials has huge potential. Biocementation involves the deposition of CaCO3 due to the metabolic activities of certain microbial species in a calcium-rich environment. When percentage of SCM used in cement-based materials like mortar increases, they tend to produce some microcracks which leads to decrement in strength and durability of the mortar. Hence, the precipitation of CaCO3 into these voids leads to a substantial enhancement in properties of concrete and mortar. This process is known as biocementation or Microbially Induced Calcium Carbonate Precipitation (MICCP). However, managing bacteria can be challenging, making it tough to implement this technology. Therefore, to overcome this issue, using directly urease enzyme was employed in this study. The present study implements the utilization of direct urease from plant seeds for precipitation of calcium carbonate. This process is termed as Enzyme Induced Calcium Carbonate Precipitation (EICCP). In the present work, EICCP is applied for enhancing the properties of mortar comprising rice husk ash (RHA). Substitution of cement by RHA in mortar was 0%, 5%, 10%, 15%, 20% respectively. The strength parameter of the biocemented RHA mortar samples were investigated and contrasted with untreated control samples. The outcomes uncovered enhancement in the strength parameter of biocemented RHA mortar samples when contrasted with control RHA mortar samples.
