AbstractA method to generate biocementation in sand using the microbially induced carbonate precipitation (MICP) process and calcium source produced from eggshell is presented in this paper. Instead of using calcium chloride or other calcium salts, soluble calcium was produced by mixing eggshell with vinegar and used for the MICP process. The compressive strength and permeability of sand treated using this method were measured using unconfined compression and permeability tests. A comparative… CONTINUE READING
