Study on the Flexural Strength of Glass Fiber-Reinforced M20 Grade Self-Healing Concrete Using a Novel Technique Microbial-Induced Calcite Precipitation

The objective of this study is to quantify the influence of glass fiber on flexural strength of the M20 grade self-healing concrete by using a novel technique microbial-induced calcite precipitation. Two groups consisting of 18 samples in each were prepared for collection of data. One is prepared without the addition of glass fiber and the other is with the addition of glass fiber. Bacteria bacillus subtilis was prepared in the bioinformatics laboratory using a strain brought from Hi media laboratories. The data were analyzed using statistical software called SPSS. The mean flexural strength of bacterial concrete without fiber was 7.944 N/mm2 and the mean flexural strength of glass fiber-reinforced concrete was 8.666 N/mm2. The significance of the events was 0.028 (p < 0.05). Glass fiber-reinforced M20 grade self-healing concrete had more flexural strength compared to conventional M20 grade self-healing concrete which were made by using a novel technique microbial-induced calcite precipitation. The percentage increase in strength of glass fiber-reinforced M20 grade self-healing concrete was 9%.
