Abstract

Concrete is the most popular material used in construction. In fact, concrete lies in its resistance to compressive forces. However, the drawback of the concrete materials is weak in tension. Because of its weakness, it can cause cracks in the concrete. One way to handle cracks in the concrete is to make bacteria-based concrete. In this research, the type of bacteria used in concrete mixing is Bacillus megaterium. The purpose of this research is to study the effect of Bacillus megaterium on the flexural strength of concrete. The bacteria proportions of 1% and 2%, which are adopted in this study, were combined with fly ash as an additive material. The specimens were casted into beam molds sized (500x100x100) mm and then tested under a threepoint bending machine to observe its bending capacity. The flexural strength of bacteria-based concrete was observed for some periods, namely 14 days and 28 days. From this research, it can be concluded that the flexural strength of bacteria-based concrete was raised up to 14,64% compared to virgin concrete.
