Study on the tensile strength of plastic fiber reinforced M20 grade self-compacting bacterial concrete using a novel microbial technique microbial induced calcite precipitation

Abstract

Aim: The objective of this study is to quantify the influence of plastic 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-healing concrete and group-2 refers to the plastic 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 plastic fiber reinforced self-compacting concrete increased by 3.73% when compared with the normal self-compacting concrete. The standard deviation of the tensile strength of plastic reinforced bacterial concrete was 0.28965. A significant difference between the two groups was observed with a p-value of 0.010 (p<0.05) Conclusion: From this experimental study it is concluded that the plastic fiber reinforced M20 grade self-healing concrete has greater tensile strength than the normal self-compacting concrete.
