Abstract

Such growth in construction, as well as development, calls for a steady supply of green construction materials that does not lead to high energy consumption and generation of excessive carbon dioxide. However, concretes, which are the most popular construction materials, are exposed to thermal cracking that is caused by insufficient tensile strength in them and which may damage their integrity and life duration. This study investigates the applicability of Fly Ash as a partial cementitious material in producing bio concrete through Microbial Induced Carbonate Precipitation (MICP), which can also incorporate microorganisms. Bacteria added to the mix serve cracks incurred in the lifespan of the building, while fly ash needs no explanation for being a good alternative for improving strength by 15-30% through the course of 28 days and reduce CO₂ by 30%, removing environmental CO₂ footprint to 262.57 kg/m3. An additional bonus is that the combo of fly ash and bacteria also reduces the material costs for the construction by 15-20% which will not only be environment-friendly but also economical in comparison with other methods. This integration process of bacteria and fly ash paves the way for a minimum of 15-20% cutback in the material expenses required.
