Abstract
The Fibre Reinforced Bacterial Concrete is a combination of concrete matrix and embedding
bacteria in the concrete is to provide crack resistance, crack control and gives high strengths and ductility. It has been
found that FRBC added in specific percentages concrete improves mechanical properties, durability and serviceability
of structures. In this paper effect of Glass fibres in Bacterial (Bacillus Subtilis) concrete on the strength of M-25
grade have been studied by constant bacteria percentage of 0.2% of weight of cement and varying the fibre
percentages of 0.5%, 1.0%, 1.5%, 2.0% of weight of concrete. All the specimens were tested for a curing period of 3, 7,
14 and 28 days. The results of FRBC for 28 days curing it has been found and also durability tests on same samples
carried out for 7 days after 28 days curing period. In this study it is found that there is a significant increase in
strength and durability. And also little decrease was found in workability due to presence of fibres.
