N2  - This paper studies the effect of slag cement to the properties of mortar such compressive strength, flexural strength, workability and drying shrinkage. From the compression and flexural test, it was found that the increase in strength by time goes achieved at 70 percent replacement, even though it was still lower than control mortar. However the strength achieved for both sample was not differ too much where the strength was 13.41 MPa and 16.46 MPa in compression and 0.99 MPa and 1.21 MPa in flexural for curing in air and water respectively at 70 percent replacement while control mortar gave 20.82 MPa and 20.54 MPa compressive strength and 1.62 MPa and 1.56 MPa flexural strength for curing in water and air respectively. At aged 7 days, mortar containing 80 percent slag cement gave the highest flexural strength, 1.32 MPa but from whole results in both strength tests, the strength was reduced by the time goes. The strength achieved was only 0.69 MPa and 0.52 MPa in flexural and 5.82 MPa and 5.25 MPa in compression for water and air curing respectively. In drying shrinkage, it was found that mortar incorporating slag cement gave the greater results than control mortar but at 80 percent replacement in air curing condition, the shrinkage was obviously decrease and lower than control mortar at aged 13 days and beyond. Therefore from all of the strength achieved, it proved that the 70 percent replacement is more suitable to be used as cement partial replacement. -Author
