摘要：
Unconfined compressive strength tests and calcium carbonate (CaCO3) quantitative chemical tests are conducted on artificially cemented sand which have different cement ratio (C-v) and curing time (t). Through the analysis of experimental results, the unconfined compressive strength (q(u)) of cemented sand are affected by curing time (t), cement ratio (C-v) and void ratio (eta). Test results show that the longer the curing time (t), the lower the void/cement ratio (eta/C-v) and the higher calcium carbonate/calcium hydroxide content ratio (CaCO3/Ca(OH)(2) ratio or m(c)/m(H)), the higher the unconfined compressive strength (q(u)) of cemented sand. It is established the compressive strength equation based on the variables of cement ratio (C-v), void ratio (eta) and curing time (t). By m(c)/m(H)-q(u) curve analysis, it is obtained the quantitative relation of chemical composition and mechanical strength.
