Concrete, as one of the essential construction materials is responsible for a vast amount of emissions. Using recycled materials and gray water can considerably contribute to the sustaina-bility aspect of concrete production. Thus, finding a proper replacement for fresh water, in the production of concrete, is significant. The usage of industrial wastewater, instead of water in the concrete can be considered in this paper. In this study, 450 concrete samples are produced with different amounts of wastewater. The mechanical parameters such as slump, compressive strength, water absorption, tensile strength, electrical resistivity, rapid freezing, half-cell potential, and appearance are investigated. The results showed that the usage of industrial wastewater does not significantly change the main characteristics of concrete. Although, increasing the concentration of the wastewater can decrease durability and strength features nonlinearly.

Concrete Production

Concrete, as one of the essential construction materials, is responsible for a vast amount of emissions. Using recycled materials and gray water can considerably contribute to the sustainability aspect of concrete production. Thus, finding a proper replacement for fresh water in the production of concrete is significant. The usage of industrial wastewater instead of water in concrete is considered in this paper. In this study, 450 concrete samples are produced with different amounts of wastewater. The mechanical parameters, such as slump, compressive strength, water absorption, tensile strength, electrical resistivity, rapid freezing, half-cell potential and appearance, are investigated, and a specific concentration and impurities of wastewater that cause a 10% compressive strength reduction were found. The results showed that the usage of industrial wastewater does not significantly change the main characteristics of concrete. Although increasing the concentration of wastewater can decrease the durability and strength features of concrete nonlinearly, the negative effects on durability tests are more conspicuous, as utilizing concentrated wastewaters disrupt the formation of appropriate air voids, pore connectivity and pore-size distribution in the concrete.

This paper reports an experimental investigation on the mechanical and durability properties of concrete using dredged marine sand (DMS). Two sources of DMS were used and the influence of water treatment prior to mixing concrete was studied. Compressive strength, tensile strength and elastic modulus of concrete with DMS were evaluated and compared with concrete made of river sand. The corrosion performance of reinforced concrete using sea dredged aggregate was examined by half-cell potential test. The results showed that the grading of DMS is suitable for concrete production. The compressive strength values of concrete specimens made with DMS are slightly higher than that of concrete made with RS. The water cleaning method is effective to minimize the chance of steel corrosion by reducing the chloride content in DMS aggregates. The results from half-cell potential test indicated that the potential values of specimens with DMS are comparable to that of specimens with RS and hence the possibility of corrosion is low. The study revealed that DMS soon after washing, could be used as an alternative to river sand.
