Abstract: Microbial solidification technology can effectively enhance the strength of sandy soil, but it will cause obvious brittleness. There are a large number of discarded clothes, which are prone to cause environmental pollution. This paper proposed a method combining the reinforcement of discarded clothing fiber with microbial solidification. Polyester and pure cotton clothing fibers with mass fractions of 0%, 0.1%, 0.2%, 0.3% and 0.4% were uniformly mixed with standard sand, and then the sand samples were solidified based on microbially induced carbonate precipitation (MICP) technology. The results showed that discarded clothing fiber not only enhanced the mechanical strength of MICP-treated sand samples, but also increased the ductility of the sand samples. An appropriate amount of fiber was randomly distributed in the sand samples to form a network structure, which could restrain the displacement of sand particles, increase the strength and improve the brittleness of MICP-treated sand samples. Taking all indicators into account, the reinforcing effect of polyester clothing fiber was superior to that of pure cotton clothing fiber, and the optimal fiber content was 0.3%. This research provides an effective method for recycling discarded clothes and promotes the application of fiber-reinforced MICP-treated sand in practical engineering. [ABSTRACT FROM AUTHOR]
