內容簡介The followings points were clarified through an investigation on the thermo-mechanical properties of low cement castable with added AE and foaming admixtures with air-entraining properties. 1. The dynamic elastic modulus and static elastic modulus decreased in proportion to the additive quantity. 2. The static thermal stress has a correlation with the fine pore quantity and the average fine pore diameter. 3. The temperature difference of the maximum value for static stress and dynamic stress depends on the existence of a visco-elastic area in the high temperature region. 4. The decrease in the elastic modulus and thermal stress accompanying an increase in quantity of fine pores may be explained by the rise of internal friction in the intermediate temperature region.
