Performance Evaluation of Rice-husk Ash Based Bacterial Concrete

Abstract

The performance evaluation of bacterial concrete made with Rice Husk Ash (RHA) is presented in this paper. Concrete is the most widely used construction material on the planet, and because of its longer service life than other building materials, it is sometimes viewed as indestructible. Continuous exposure to harsh weathering, on the other hand, causes an increase in concrete porosity and, as a result, a reduction in mechanical properties. The effect of concrete permeability on porosity and porosity connection. Microbial concrete, which uses microorganisms to increase the durability and life of the concrete, has been presented. These bacteria are employed to precipitate calcium carbonate in concrete, which is extremely desired because the calcite precipitation caused by microbial activity is pollution-free and natural. Rice husk is used to substitute fine aggregate in concrete mixes of 0, 5, 10 and 15.
