Now a day the waste material from industry are speedily growing. To utilize such materials and to reduce such type of waste in environment, the sand is replaced by the coal bottom ash contain of bacteria species called bacillus pasteurii in M40 design mix in this study. This thesis was study the material properties (cement, sand, coarse aggregate, coal bottom ash), way of preparation, procedure of test and ingredients used for culturing of bacteria species in laboratory and with all procedure. This study provides results on experimental investigations carried out to evaluate the effects of replacing aggregates (fine or sand) by coal bottom ash 20%, 30% and 50% in bacterial concrete with all other ingredients as constant. An experimental program was designed by analyzing the flexural strength and compressive strength properties of normal concrete, bacterial concrete with and without coal bottom ash at curing period 7, 28 and 56 days. As a result of this study bacterial concrete with 30% coal bottom ash has been maximum compressive strength and flexural strength than all concrete including in this experiment. Generally bacterial concrete with coal bottom ash has been better flexural strength and compressive strength than bacterial concrete and normal concrete. Improved the strength of bacterial concrete by coal bottom ash therefore, recommended that utilize coal bottom ash as replacing fine aggregate in bacterial concrete that gives the environment to eco-friendly.
