| Abstract | |
This study aimed at supporting processes and techniques for minimization of water consumption in the production of concrete. For this purpose, the use of treated wastewater from a wastewater treatment plant (WWTP) in interlocking concrete paver block (ICPB) production was evaluated. The treated wastewater was added in various dosages (0%, 50%, 75% and 100%) to the water used to produce cylindrical concrete samples. These samples were evaluated for compressive strength and water absorption tests. After these evaluations, the dosage of 100% treated wastewater for concrete production was established and ICPB were produced with this water composition. Subsequently, an area in a parking lot was replaced by ICPB produced with treated wastewater, and an equal area was replaced by ICPB produced with potable water. A comparison between parameters obtained for cylindrical samples and ICPB samples prepared with treated wastewater and those prepared with potable water indicated that wastewater reuse would be a good alternative for potable water consumption reduction in the concrete industry.
