Study of the Concrete Properties of Granite Pit and River Sand Concrete Properties

Abstract

This study developed the study of the concrete properties of granite pit and river sand concrete properties. Sand and gravel represent the most widely consumed raw material on earth after water, and between 64-75% of aggregate mined each year is used for making concrete. The construction projects in Ethiopia mainly use river basin fine aggregate for concrete mix. The increment in demand and rapid extraction of river sand cause deepening of the river beds, loss of vegetation on the bank of rivers, and disturbance to aquatic life and agriculture. Therefore, a total of 43 mix designs by using the American Concrete Institute mix design method and the concrete 264 cubes specimen with 150 x 150 x 150 mm sizes were prepared at 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%   and 100% replacement with NWWGPS and WWGPS for C-20, C-25 and C-30 at 7^th and 28^th curing days. Finally, some of their results show the compressive strength of concrete enhanced by the replacement of river sand with washed granite pit sand.
