EFFECTS OF ACID AND HIGH-TEMPERATURE TREATMENTS ON DURABILITY OF BACTERIAL CONCRETE

Abstract

Bacterial concrete specimens were produced in this study to investigate the effects of microbially induced calcium carbonate precipitation (MICP) mechanism on concrete durability. Bacterial concrete (BC) samples were produced through supplementation of Bacillus megaterium bacteria into concrete mixture and curing water. However, control concrete (CC) samples were produced without bacteria. BC and CC were exposed to acid (HCl) and high temperature (400C) treatments. In the first phase of the study, 100×100×100 mm cube specimens were immersed into HCl solution for 10 days and compressive strengths and weight losses were determined. Compressive strength of acid-treated samples was measured as 25.08 MPa for BC samples and as 17.90 MPa for CC samples. Such values revealed that BC samples yielded 40.11% greater compressive strength. When CC samples lost 10.99% weight due to acid attack, BC samples lost 8.74% weight. In the second phase of the study, concrete specimens were exposed to 400°C temperature and compressive strength of heat-treated samples was determined. As the result of high temperature, bacterial samples yielded 13.76% greater compressive strength against high temperature. Present findings revealed that CaCO3 formation on concrete improved concrete durability against attacks and high temperatures.
