xv, 87 p. : col. ill. ; 30 cm. Consisting of silicates, iron and other compounds, slag cement is the by-product of molten iron production in a blast-furnace. Also known as ground granulated blast¬furnace slag, slag cement often used in concrete requiring maximum durability and higher strength. This study is to investigate the behavior of slag cement as a partial replacement material for Portland cement up to 30% and 40% of slag cement and its effectiveness in improving the properties of mortar. It was achieved by compression test and flexural test conducted to determine the highest strength development between samples for 7, 14 and 28 age days of curing time. There were three types of samples that has been tested according to BS 4551: Part 1: 1998, which are mortar containing 30% of slag cement, 40% of slag cement and mortar with plain ordinary Portland cement as the control samples. At the age of 28 days of curing, mortar containing 30% and 40% of slag gave compressive strength of 5.945 MPa, 11.51 MPa for air curing and 6.076 MPa, 12.34 MPa for water curing respectively and gave flexural strength of 2.2 MPa, 2.384 MPa for air curing and 2.249 MPa, 2.549 MPa for water curing respectively. Besides, this studies also to investigate the effect of curing condition to strength development and drying shrinkage of samples containing 30% and 40% of slag, where samples with water curing achieved higher strength development and low shrinkage rate than the samples with air curing. The used of concrete as samples besides mortar is recommended for future works and studies. -Author specialized Nor Hidayah binti Hazali Project paper (Bachelor of Civil Engineering) -- Universiti Malaysia Pahang - 2007 Slag cement Cement Building materials THE0002483(Local) UMP 080624 20251114204415.0 vtls000029644
