EXPERIMENTAL INVESTIGATION ON THE COMPRESSIVE STRENGTH OF CONCRETE BY USING QUARRIED RIVER SAND AND SUPPLIED SAND
The construction industry in Ethiopia is booming sector because of increased public investment on development projects and private investments. So in this wide industry, Failure of concrete structures leading to collapse of buildings has initiated various researches on the quality of construction materials. Sand, as one of the most accessible natural resources, has been used mostly as a construction material since the earliest days of civilization. It is defined as continuously graded unconsolidated material (sediment) present on the earth's surface as a result of the natural disintegration of rock. The sand is an inert element essential in the composition of concrete; its use ensures granular continuity between the cement and gravel for better cohesion of concrete. In Ethiopia, rivers sands are transported kilometers away from Addis Ababa. So Supplying of natural sand from the quarry site is exposed for so many irregularities which affect the Compressive property of concrete. Natural sand should be free from impurities which are intentionally added. Visit to the two different sites has been made by means of high way transportation to collect the sand sample. To achieve the research objective, Quarried &Supplied sand samples for laboratory investigation were collected from Ziway and Gorro (Addis Ababa).This experimental study has been under taken to investigate the compressive property and durability of concrete using the quarried and supplied sand from the same source by conducting Tests. The Experimental Test results have displayed that there is compressive test result difference between the quarried and the supplied sand with the same mix proportion.
