Employing Saline Water in the Concrete Manufacturing Process
Fresh water scarcity is one of the major concerns in the world nowadays due to amid global warming and rapid increase of population. For this reason, this study investigates the potential incorporation and feasibility of replacing fresh water with seawater as mixing and curing water in the concrete manufacturing process. To meet this objective, various mixtures were prepared with various levels of strengths while incorporating different corrosion protection measures to minimize steel corrosion. The properties of the concrete were evaluated through fresh tests as slump, unit weight, air content and temperature. In addition to that, mechanical properties namely compressive strength, flexural strength and bond strength were obtained. Also, accelerated corrosion testing through impressed voltage method was carried out. A feasibility study was conducted to quantify the cost savings resulting from replacing freshwater with seawater in mixing and curing concrete. The study attempts to identify measures for careful incorporation of sea water into concrete. Test results show that sea water concrete has potential to replace fresh water concrete as long as protective measures are applied.
