Controlled low strength material(CLSM) is a flowable mixture and does not need to compact. It is composed of sand as a fine aggregate, fly ash, cement as a binder and water. Since it is getting more difficult to obtain sand in Korea, some researchers have been studying to replace sand with other aggregate, such as bottom ash. In this study, a study was carried out to find feasibility of specially designed binders to replace cement as a binder. Conventional CLSM requires only 3～7% weight cement because unconfined compressive strength of CLSM dose not exceed 1.0 ㎫ for re-excavation after its placement. However in the case of large amount of CLSM is going to be produced, amount of cement is not small anymore. Flow tests were carried out for 12 cases. Some of the total cases have different combination of fine aggregate between Jumunjin sand and Bottom ash while rest have different combination of biner between portland cement, 2 kinds of cementless binders which are activated different mechanism.
