Abstract
Abstract
Since the cost of cement increases and the pollution to environment due to greenhouse effect are becoming more serious year by year, thus, dolomite fines subjected to replace the cement in concrete mix as it has lower cost compared to cement and it is obtain directly from the Earth ground without any manufactured process. Dolomite fines also shows almost similar physical and chemical properties as cement. The various replacement of cement with dolomite fines carried out in this study is 0%, 5%, 10%, 15% and 25%. The grade of concrete sample designed to be 30. The properties of concrete sample in terms of physical characteristics; slump, density and water absorption for various percentage replacement are determined in this study. In this study, it shows the dolomite fines are lightweight aggregate compared to the cement and the water absorption of is lower compare to that of the control concrete.
