This study was performed to obtain the basic data which can be applied to the use of foaming mortars. At the mixing ratio 1 : 1, the highest strengths were shown by foaming mortars. The decreasing rates of strengths increased in poorer mixing ratio and addition of more foaming agent. The strengths decreased up to 77.0-92.8% by mix-foaming type and 36.7-74.4% by pre-foamed type than cement mortar. At the mixing ratio of 1 : 1, the lowest air contents were shown by foaming mortars. The increasing rates of air contents increased in richer mixing ratio and addition of more foaming agent. Air contents increased up to 26.0-63.8 times by mix-foaming type and 5.8-17.7 times by pre-foamed type than cement mortar, respectively. The correlations between compressive strength and air content were highly significant
