Experimental Investigation on RO Waste Water in Concrete

As a sustainable approach this project is conducted to investigate the possibility of RO waste water in concrete, concrete is the most widely used construction material in the world. Production of Portland cement used in concrete produces 2.5 billion tonne’s of carbon dioxide and other greenhouse gases worldwide. Furthermore, one of the sectors that uses the most water is the concrete industry. It is estimated that 150 litres of water are needed. for per cubic meter of concrete mix. Demand of fresh water by the construction sector is expected to increase due to high increase in the growth of construction activities in India. Without taking into account the additional uses of water in the concrete industry, water is a serious environmental problem, and water availability and quality are getting worse globally. The present study focusses on making concrete by including waste water from reverse osmosis into the mixing and curing process. Four mix amounts of different materials make up the experimental technique in water cement ratios. Fresh concrete is tested for workability. Cubes were casted and tested to find out compressive capacity of concrete. Test results of potable water concrete and RO waste water concrete will be compared.
