Method of manufacturing soil reinforced by microbe-based bio-binders and soil produced by the method
The present invention relates to a method of manufacturing soil reinforced by microbe-based bio-binders and soil produced by the method. The bio-binders are not harmful to humans, do not cause environmental pollution and secure sufficiently the soil strength and resistance against wind. According to the method, the soil is prepared by binding sand whose major components are silica and alumina, ureolytic microbes, urea, calcium ion, and polymer fibers, and the content of polymer fibers in sand ranges from 0.05 wt % to 5 wt %. In addition, it is preferable that the microbes provide CaCO3 at a rate at 1˜7×10−9 g CaCO3 ppt cell−1 hr−1 under optimum conditions.
