This paper deals with slag cement concrete without utilizing portland cement. The results of he experimental studies are summarized as follows. The slag cement can be made conveniently with industrial wastes of granulated slag and gypsum from the desulfurization process. The most preferable slag-gypsum ratio was found to be 9:1. With the slag cement, the compressive strength of concrete ranging from 250 kg/cm^2 to 450 kg/cm^2 can be obtained easily. When W/C is in the range of 45〜65%, the nature of σ_<28>〜C/W curve is linear, which is the same as ordinary concrete. The slag cement concrete has an advantage of low heat of hydration and disadvantages of long setting time, rapid carbonation and small air content in the case of AE concrete. The rest of the properties are similar to those of C-PB cement concrete.
