A method for considering curing temperature effect in

Conventional mix proportion design of cement-solidified mud (CSM) used as fill material is usually based on the past experience in Japan. Nevertheless, the actual field curing temperature (T) of a new CSM project can be quite different from the Japan’s case, particularly in a different climate zone. As a consequence, Japan’s experience possibly leads to inappropriate design of mix
