Feasibility of Utilizing Treated Domestic Wastewater (TDW) for the Production of Concrete
Freshwater scarcity is expected to become one of the biggest concerns globally, with the construction industry accounting for as much as 30% of global freshwater use over the life cycle of civil infrastructure today. Water management and its potential to practically alleviate water scarcity and increase the sustainability of concrete therefore need more consideration in scientific research. Existing research suggests that non-potable water such as treated domestic wastewater (TDW) could be used to produce structurally sound concrete for the construction industry. Consequently, this research study was conducted as a pilot project to assess the feasibility of utilizing treated domestic water to produce good quality and durable concrete in South Africa. Chemical analyses of the TDW samples, evaluation of the concrete setting time, slump retention and 7-day and 28-day compressive strength tests were performed in the study. While no definitive correlations of using TDW on the setting time and workability of concrete could be deduced, the majority of the recorded effects were surmised to be acceptable for the concrete industry in South Africa. In addition, while using TDW as mixing water delayed the compressive strength development of the concrete samples, the samples still attained sufficient compressive strength at 28 days to pass the stipulations of the standard. The findings of this study show that TDW produces concrete with sufficient workability, setting time, and compressive strength to be used in the local construction industry. However, quality control of the TDW is vital to ensure the consistent production of good quality concrete.
