Durability Studies on Self-compacting Concrete – Bacterial Concrete

Abstract

Self-compacting concrete (SCC) is a homogenous concrete having good workability conditions with less water-powder ratio and this concrete eliminates the vibration during the placement. Concrete faces many environmental impacts on the surface or to a certain depth which affects the structure and the reinforcement. This paper shows the durability tests on SCC bacterial concrete such as a water permeability, acid attack, sulfate attack, and pH tests. Bacteriacultured water is mixed for making the bacterial concrete and then the cube is moulded to conduct the test with different bacteria species. Due to chemical curing of 60 days done after the normal curing of 28 days in a cube size 150 x 150 x 150 mm, it is found to be the strength of bacterial concrete. And the pH value shows the base in nature. The permeability of the concrete also tested. The compressive strength decreased for some species of bacteria and for some species the values are merely equal to conventional SCC concrete. Finally, the SCC bacterial concrete holds good results in durability concerns. This is happened due to nano size of the bacteria mixed with concrete increases the efficiency and life period.
