Use of treated domestic wastewater before chlorination to produce and cure concrete

Concrete samples with different amounts of cement and superplasticizer admixture produced with both drinking water and treated wastewater and cured with treated wastewater before chlorination. The 28-day compressive strength of all of the concrete samples was 93-96% of the compressive strength of the control samples. A 28-day tensile strength of all samples was 96-100% of the tensile strength of the control samples and the setting time was increased by 15 min. Concrete samples produced and cured with treated wastewater did not have a significant effect on water absorption, slump and surface electrical resistivity. A one-way analysis of variance (ANOVA) at the 5% significance level indicated no significant difference between concrete samples produced and cured with treated wastewater and control samples at the age of 90 days.
