PURPOSE:To obtain the hydraulic composite material having a high slump value, small in change with the lapse of time and with its applicability and strength improved by mixing the inorg. solid grains having a specified diameter distribution, solid grains, a surfactant and water in a specified ratio. CONSTITUTION:The hydraulic composite material contains inorg. solid grains (grain A) having 5Angstrom -0.5mu diameter and in which the grains having <=50Angstrom diameter are controlled to <5wt.% and a surfactant, and the grains are mixed in the following ratio. Namely, the amt. of grain A is controlled so that the grains B are brought into contact with one another in the composite material without being deformed and closely packed without causing bridging, and the ratio of the grain A to the grains A plus grains B is controlled to 0.1-50vol.%. In addition, the weight ratio of the water to the grains A plus grains B is controlled to 0.1-0.3, and the weight ratio of the dry surfactant to the grains A plus grains B is controlled to 0.6-1.0. |
