The use of concrete in the construction industry is never ending and so are their complementary ill effects. Thus, they should be handled within the stipulated time and in a sustainable manner. The major idea of the present research work is to assess the strength parameters of the concrete specimens made by inducing bacteria along with a suitable cement replacing substance. Therefore, the use of sustainable strategies like inducing bacterial culture into the concrete mix can act as an active support for both nature as well as the economy of construction industries. There are many substitutes which are used for replacing cement. In this paper, control concrete, concrete made by replacing cement with 8% of Micronized Biomass Silica (MBS) and bacteria induced concrete are compared. The bacteria used is Bacillus Sphaericus and is mixed in the concrete specimens at different levels of 10ml, 20ml, 30ml. M60 grade high strength concrete is casted in the form of cubes and cylinders and their compressive strength and split tensile strength at the age of 7and 28 days are compared with that of conventional concrete. From the test results, it was concluded that, specimens with 20ml bacteria and 8% MBS showed optimum results. Hence, this combination of bacteria and MBS would not only increase strength but also help the concrete against moisture and other harmful particles. © 2019 Elsevier Ltd.
