PURPOSE: A composition for improvement of soft ground is provided to fill pores among soil particles by calcium carbonate, to generate calcium carbonate through a growth of applied microorganism by applying microorganism to the soft ground. CONSTITUTION: A composition for improvement of soft ground contains a microorganism solution, a calcium chloride solution, and a foaming agent, and carbonate ions obtained through a decomposition of microorganism of the solution. By the foaming agent, air is supplied to microorganism. The microorganism solution is obtained by mixing water, microorganism medium, urea, and microorganism liquid. The molar density of the calcium chloride solution is 0.1-5 M. |
