| In recent years, the microbial induced calcium carbonate precipitation method ( MICP) using the mechanism of urea hydrolysis has been broadl y examin ed for the treatment of rock, sand, mortar , and concr ete. Resear chers have been studyin g the addition of microb ial solution to mor tar or concrete during mixi ng and later curing in cementation solu tion or the simultaneous add ition o f microb ial solution an d cement ation solution to concr ete duri ng mixi ng. In this study, a low-cost microbial solu tion obtained from ureolyt ic bacteria culture d in the low-c ost corn steep liquor med ium is used instead of water to mak e cement -sand mor tar. The result s suggest that the 28- day com pressiv e strength of cement-sa nd mortar samples rose by 65 % com pared to the cont rol sample s and its water absorption decreased roughly by this method, with 1/3 M equimolar urea and calc ium chlo ride solu tion used as curi ng solution. Given the low cost of corn steep liquor medium, the microbial techniq ue can be a pplied to improv e the compres sive strength and durabilit y of mor tar and concr ete. |
