| Summary: | The use of bacterial concrete has become popular as a way to fix fractures in a variety of constructions, including pavements, pipelines, canal linings, bridges, and reinforced concrete buildings. Concrete constructions frequently have cracks that let water and other chemicals in, weakening the structure and compromising reinforcement. Henk Jonkers came up with the idea of bacterial concrete to solve this issue. Concrete cracks were sealed experimentally using calcium lactate and Bacillus subtilis. The bacteria that were chosen were those that could thrive in alkaline conditions. M20 and M40-grade concrete mixes substituted river sand and crushed stone sand for fine aggregate with varying proportions of B. subtilis and calcium lactate. At various curing ages, the study looked at how bacteria affected abrasion resistance. For various mixtures, empirical relationships were proposed between various concrete properties and bacterial content. |
