Study the Effects of Using Different Water Types on the Mechanical Properties of Concrete

Abstract

The issue of water sustainability is a major topic due to the lack of water sources and the scarcity of drinking water, so the search for alternatives began. In this paper, the effect of using three water sources will be studied (the tap water ( as control reference mix.), the Tigris River, and the Pepsi Company factory). To study the physical and chemical properties, and the effect of this water on the concrete mixture, and for each source the concrete mixture was placed in cube molds and cylinders. Put the concrete mixture in a water basin for curing. Compression and splitting tests are performed at intervals of (7-28-90) days to evaluate these mixtures. From the results it was found that the compressive and splitting strength of concrete for tap water, Tigris River and Pepsi factory, which was recorded at the age of 7 days, the compressive strength of cubes was an average of 18.5 MPa, 19 MPa and 13 and the splitting strength was an average of 1.5 MPa and 1 .4 MPa and .5 maps, respectively, at the age of .28 days, which were recorded at 32.1 MPa, 19 MPa, and 16.4 MPa, respectively, and the splitting strength was 3 MPa, and 7. 2 MPa, and 5.1 MPa, respectively, and at 90 days they were 36 MPa, 32 MPa, and 18 MPa, respectively, and the splitting strength was 2.3 MPa, 3 MPa, and 1.4 MPa respectively also was observed a decrease in compressive strength And splitting by 1/3 for Pepsi Baghdad company factory wastewater samples. Finally, the drinking water and the water of the Tigris River was suitable for making concrete mixtures
