| Abstract: | Research purposes:Based on summary of mechanism of soil improved by lime (cement)and problems encountered in quality test of improved soil,the paper analyzes the problems encountered in the field from theory,experiment test and construction control aspects. Researeh results:The paper proposes that the best method to solve these problems mentioned above is to coordinate the time relationship between laboratory test and construction in field and to determine calibration value of reasonable and stable maximum dry density.Finally the paper cites examples to illustrate the mathematical method for solving the problems. |
| Keywords: | soil improved by lime (cement) delayed time dry density maximum dry density |
