Comparative study of concrete constructed using wastewater and potable water
Abstract 80% of the water supplied, normally comes out as wastewater either domestic or industrial. The utilization of wastewater in concrete will reduce potable water usage in the construction industry. Approximately 150 litres of water are required for lm3 of concrete without considering other applications of water in the concrete industry. This research study has investigated the performance of concrete using wastewater. 60 total number of concrete cubes have been designed and constructed using 10%, 20%, 30% and 100% of wastewater. The experimental data indicated that 30% of wastewater content in the concrete mix have increased 18% of the concrete strength compared with the control sample. Meanwhile, the result of the X-Ray Fluorescence Test (XRF) test for the concrete sample recorded that the CA is higher than the 30% concrete sample.
