Dataset of producing and curing concrete using domestic treated wastewater

Abstract

We tested the setting time of cement, slump and compressive and tensile strength of 54 triplicate cubic samples and 9 cylindrical samples of concrete with and without a Super plasticizer admixture. We produced concrete samples made with drinking water and treated domestic wastewater containing 300, 400 kg/m3 of cement before chlorination and then cured concrete samples made with drinking water and treated wastewater. Second, concrete samples made with 350 kg/m3 of cement with a Superplasticizer admixture made with drinking water and treated wastewater and then cured with treated wastewater. The compressive strength of all the concrete samples made with treated wastewater had a high coefficient of determination with the control concrete samples. A 28-day tensile strength of all the samples was 96–100% of the tensile strength of the control samples and the setting time was reduced by 30 min which was consistent with a ASTMC191 standard. All samples produced and cured with treated waste water did not have a significant effect on water absorption, slump and surface electrical resistivity tests. However, compressive strength at 21 days of concrete samples using 300 kg/m3 of cement in rapid freezing and thawing conditions was about 11% lower than concrete samples made with drinking water.

Reinforced concrete deterioration caused by contaminated construction water: An overview

“…The use of drinking water for mixing concrete, as recommended in standards, gives higher strength compared to those made with wastewater [2]. This again supports the need to use potable for concrete production.…”

“…Also, Al-Ghusain and Terro [17] reported that there was an increase in the slump when different wastewater with different treatment levels were used in mixing concrete. However, Asadollahfardi et al [2] found no significant effect on slump when treated wastewater was used to make concrete. This non-consistent result in slump could be as a result of the drastic reduction of impurities in the wastewater after treatment.…”

“…Whereas, the presence of bicarbonates in a concrete mix either increases or reduces the setting time of the concrete. Also, Asadollahfardi et al [2] reported that the use of wastewater for making cement paste increases the setting time. The extension of the setting time by wastewater has been attributed to the presence of impurities, which delay the setting process.…”

“…The concrete industry is one of the sectors that consume a higher quantity of freshwater [2]. Approximately 1 billion cubic meters of water is used annually to mix concrete.…”
