Abstract: Basalt fibre (BF) is a novel sort of inorganic fibre which is produced from the expulsion of liquefied basalt shake and is industrially accessible. This investigation relatively examines the use of basalt and glass strands as fibre support in concrete. This paper also gives a concise portrayal of impact basalt and glass fibre on workability and compressive strength of microbial concrete. The fibres were added in concrete randomly by (0.25%, 0.5%, and 0.75%) of the weight of cement. For every percentage of fibre, a total of three cubes were cast to obtain average results. Addition of fibres into concrete greatly improves the engineering properties of concrete. Be that as it may, the compressive strength of concrete is still under level-headed discussion by the addition of fibres in concrete. There is no considerable improvement in compressive strength of concrete by the addition fibres. To improve the compressive strength of concrete there is a novel technique by the addition of Bacillus bacteria and its nutrients to concrete may in improves the mechanical properties of concrete. The bacteria used in this study are Bacillus Subtilis spore powder of 2 million CFU/gm with 0.5% of cement was mixed to concrete. And calcium lactate was added to concrete as a nutrient source for bacteria in concrete. Findings of this investigation indicated the influence of added bacteria in fibre concrete which is quite impressive for improving the compressive strength and workability of concrete.
