Dissertation note: Project paper (Bachelor of Civil Engineering) -- Universiti Malaysia Pahang - 2007 Abstract: This study is to investigate the engineering properties of slag cement as partial replacement material at 50% and 60% of binder content. The slag cement is also known as ground granulated blast furnace slag (GGBS). The field of studies covers important parameters in determining the engineering properties such as compressive and flexural strength and drying shrinkage. A total of 54 cubes (70 x 70 x 70 mm) and 54 prisms (l00 x 100 x 500 mm) were prepared in three groups according to different binder content and the samples were cured under two curing conditions which were air and water curing for 7, 14 and 28 days before testing. Three types of mixtures were prepared based on the level of replacement of 50%, 60% and 0% as the control mixture. The water to cement ratio of 0.5 and cement: aggregates ratio of 1:3 were applied to all mixtures with the aggregates size are within the range of 1.18 mm to 2.36 mm. The result showed that the GGBS mixtures achieved higher compressive and flexural strength than OPC mixture for water curing condition but lower strength for air curing condition. The 60% GGBS mixture shows highest drying shrinkage strain compared to other mixture in both curing condition. Through the observation, the GGBS showed lower early strength gain but a satisfying improvement of strength as the time increased. The study demonstrated that better engineering properties of slag cement can be achieved with proper curing condition. -Author
