Study of a Novel Microbial Induced Calcite Precipitation Technique to evaluate the tensile strength of Steel fiber reinforced M20 grade self compacting bacterial concrete

Abstract

Aim: The objective of this study is to quantify the influence of steel fiber on the tensile strength of self compacting concrete using a novel microbial technique Microbial induced calcite precipitation. Materials and Methods: There are 2 groups taken for the study and a total of 18 samples were prepared per group with Gpower (80%). Group 1 refers to the conventional self-compacting concrete and group 2 refers to the steel fiber reinforced self-compacting concrete. The number of samples was calculated using clinical software by adopting the values from previously published research papers. The independent sample T-test has been carried out using SPSS software version 21 which shows a clear increment in the tensile strength of the fiber reinforced self-compacting concrete.Result:Tensile strength of steel fiber reinforced self-compacting concrete increased by 33.98% when compared with the normal self-compacting concrete. The standard deviation of the tensile strength of steel reinforced bacterial concrete was 0.80771. A significant difference between the two groups was observed with a p-value of 0.010 (p<0.05). Conclusion: In this study it is concluded that the steel fiber reinforced M20 grade self-compacting concrete has greater tensile strength than the normal self-compacting concrete.
