(57) [Abstract] [Purpose] To provide a cement composition mainly used in the civil engineering industry, in particular, a cement composition used for road paving. [Composition] 100 parts by weight of cement having a 3CaO / SiO 2 content of 60% by weight or more, 1 to 5 parts by weight of anhydrous gypsum, 0.2 to 3 parts by weight of aluminum sulfate in terms of anhydride, and 0.1% of alkali metal aluminate salt. The cement composition is composed of ˜0.8 parts by weight and steel fiber. [Effects] By using the cement composition of the present invention, road pavement concrete that exhibits good compressive strength and flexural strength in the early, middle, and long term and that can be opened in one day is obtained. Produce the effect of. |
