The strength development properties of epoxy resin mortars were investigated according to ASTM C 190 (tensile), ASTM D 695 (cylinder, compressive) and JIS R 5201 (a little modified, bending). The experimental conditions were as follows : the binder content is 15 per cent ; the aggregate is sea sand under 2.5mm produced in Nishikioka district ; the water content of sand varies in the amount of 0, l, 2, and 3 per cent ; the curing time is 1, 2, 4, 8 or 16 days ; and throe kinds of binders are used in the experiments. A11 the experiments were conducted in a 10w temperature room controlled at 4℃, 70 per cent R.H. The results obtained were as follows : (1) In case of 3 per cent of water content of sand. The bending and tensile tests showed low strength not suitable for practical use. but the compressive test yielded the strength higher than 300 kg/cm^2. The addition of 15 per cent of calcium oxide powder to the binder resulted in a rather harmful effect on all the three kinds of strength. (2) In case of 1 or 2 per cent of water content of sand. The bending, tensile, and compressive strengths of Epikote 815/Epomate RX3 type epoxy resin mortar developed with considerably good tendencies. and they were exceedingly improved by the addition of 15 per cent of calcium oxide powder to the binder. (3) In case of 0 per cent of water content of sand. The equilibrium strengths were obtained in the curing times of 1〜4 days (compressive), 2〜4 days (bending) and 2〜16 days (tensile) for these 3 kinds of epoxy resin mortars. It was found that the strength development was improved with decreasing the water content of sand.
