Apr 09, 2020  Abstract: This paper presents the study about the compressive strength of concrete made by replacing normal sand with dune sand. Dune sand replacement is done in percentages of 0,25,50, 75 and 100%. Compressive strength test was carried out on the 7 th, 14 th and 28 th day. The slump and water cement ratio were observed to increase and then decrease as the percentage of
