RELATIONSHIP BETWEEN STRENGTH AND HARDNESS OF CEMENTED-CLAY SOIL IN SHANGHAI
Unconfined compression strength of cemented-soil is often needed in the construction sites.But the common unconfined compression strength test methods have the disadvantage of high requirements and ineffective in time and test cost.For quick test of unconfined compression strength,a new method by using the hardness of cement soil to estimate the unconfined compression strength is proposed.Laboratory tests are conducted to study the relationship between hardness and curing time,cement content,unconfined compression strength of Shanghai clayey soil.The results show that there is a good linear relationship between logarithm of unconfined compression strength qu of Shanghai cemented-clay and its hardness p.During the early curing period,the growth rate of hardness is larger than the rate of unconfined compression strength.But during the late curing period,it is the opposite.
