Study on the Flexural Strength of Glass Fiber Reinforced M20 Grade Self-Compacting Bacterial Concrete

Abstract

Aim: The goal of this research is to determine the effect of glass fibre on the flexural strength of M20 grade self-healing concrete utilising a unique approach called microbial induced calcite precipitation.. Materials and methods: For data collection, two groups of 18 samples each were produced. The first group is formed without the presence of glass fibre, whereas the second group is formed with the presence of glass fibre. Bacillus subtilis bacteria were cultured in the bioinformatics laboratory using a strain obtained from Hi media laboratories. Results: SPSS statistical software was used to analyse the data. The mean flexural strength of bacterial concrete without fibre was 7.944 N/ mm2, while Glass fibre reinforced concrete had a mean flexural strength of 8.666 N/mm2. The events had a significance of 0.00 (p<0.05). Conclusion: The flexural strength of glass fibre reinforced M20 grade self-healing concrete was higher than that of conventional M20 grade self-healing concrete prepared utilising a unique process of microbial induced calcite precipitation. The strength of Glass fibre reinforced M20 grade self-healing concrete increased by 9 percent.
