It is known that cement, when mixed with wood chip, may face problems in hardening depending on the type of wood.This study examined the wood chip pretreatment effect of the method of soaking fine wood chip in 100oC water andthen drying it and the effect of hardening accelerator on the setting time, strength and thermal conductivity of normalconsistency wood chip mortar with a flow value of approximately 110%. Mortar experiment showed that use of woodchip caused the water content required to obtain the same flow value to increase and the setting time to be overly delayed.It was shown that water treatment of wood chip in boiling water to solve such problem was not so meaningful in normalconsistency wood chip mortar but that use of hardening accelerator was more effective in solving retardation of settingand improving compression strength and specific strength.
