Assessment of the Impact of Bacillus Cereus Bacteria on Strength and Water Absorption Capacity of Sustainable Concrete
This paper shows the impact of incorporating bacteria (bacillus cereus) on strength in compression and water absorbing capacity of developed sustainable concrete. The study was conducted in two parts. In the first part cement is substituted with fly ash at the rate of 5%, 10%, 15% and 20% and in the second part bacteria cereus was added to the concrete along with the fly ash replacement by using a solution of bacteria, at a rate of 10%, in place of the mixing water. The compressive strength of the conventional cement concrete got enhanced on substituting cement with fly ash. The maximum improvement was observed at 10% fly ash replacement. The bacteria incorporated samples showed further improvement in the strength as well as water absorbing capacity after 1, 2 and 4 weeks. Adding bacteria increased the 7 days strength by around 19.24%. The water absorption capacity of the fly ash replaced samples reduced considerably due to bacteria cereus and a maximum reduction of around 20.35% in the water absorption value was observed at 20% fly ash replacement. Therefore, bacillus cereus bacteria could be efficiently used to enhance the strength and impermeability characteristics of conventional cement concrete.
