MATHEMATICAL MODEL FOR PREDICTING STRESS-STRAIN BEHAVIOUR OF STANDARD GRADE BACTERIAL CONCRETE

The detailed results presented in tabular and graphical forms in chapter- 4 reveal the performance of the Bacterial Concrete and bacterial concrete with fly ash the improvement of the strength parameters when compared with the normal concrete. The microbe proved to be efficient in enhancing the properties of the concrete by achieving a very high initial strength increase and thus we can conclude that the produced calcium carbonate has filled some percentage of void volume thereby making the texture more compact and resistive to seepage. When bacterial concrete is fully developed, it may become yet another alternative method to replace OPC and its hazardous effect on environmental pollution. Hence can be used for construction as it is resistant to corrosion as well The addition of bacillus bacteria improves the hydrated structure of cement mortar .Bacillus can be produced in the laboratory which is proved to be safe and cost effective. The compressive strength of cement mortar is maximum with the addition of bacillus bacteria for a cell concentration of 105 cells per ml of mixing water. So, bacteria with a cell concentration of 105 cells per ml of mixing water was used in the
