Enhancement of Bio-Sandy Brick through Discrete Randomly Distributed Fiber
Microbial induced calcium carbonate precipitation (MICP) has attracted attention as a sustainable alternatives of soil improvement and construction materials in recent years. This paper is to develop bio-sandy brick through the MICP and to enhance it with discrete randomly distributed fiber. Four different fiber proportions (0.1%, 0.2%, 0.3%, and 0.4% by weight of dry sand) were used. The four-point bending tests were conducted. Results showed that adding fiber in the MICP treated bio-sandy brick can increase its ductility. The optimum fiber content was around 0.3%. Addition of 0.3% fiber can significantly prevent the post peak flexure strength loss and improved the ductility of bio-sandy brick that still had 400 kPa residual strength at 15% failure strain. The failure strain of fiber-reinforced bio-sandy brick reached the highest as 6.0% at 0.3% fiber addition.
