| Studies were conducted about the influences on the solidification of sand by Microbial Carbonate Precipitation of various factors like the density of the nutrient salt, the methods of injection, the discharge in the continuous injection, and so on.As the result, it was verified desirable that the period is instituted within the period in the microbial functions is active. It seems advantageous of solidification that the density of the nutrient salt and the discharge of the injection are settled considering the effectiveperiod of the injection. It is considered the injection of the thin nutrient salt with muchvolume and the intermittent injection can be effective of not solidification but also the mitigation of the environmental influence. |
