A Study On The Feasibility Of Using Industrial Waste Water For Concrete Mixing And Curing

Abstract

Concrete an artificial stone like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips etc.) water admixtures etc. in specific proportion. The strength and quality are depended on the mixing proportion. Water is the most important & least expensive ingredient of concrete. It plays an important role in mixing, laying, and compaction, setting & hardening of concrete. This research investigated the feasibility of using industrial waste water for mixing and curing of concrete by checking the compressive strength of concrete. Samples of water collected from three different sources, Tap water, Industrial Waste Water and Mineral water. 8-inch height and 4- inch diameter of cylinder samples were cast with these water samples. Compressive strength test was carried out on the cylinder and the findings were statically processed. The results indicated that sources of water used in mixing concrete have a significant impact on the compressive strength of the resulting concrete. Also, using Industrial Waste water for concrete casting and curing reduces the strength greatly. For important construction works, using industrial waste water will never be recommended. But for making concrete where strength is not important such as for creating blocks for embankment, waste water can be a good source as this will reduce the amount of waste mixing in the natural water sources and it will reduce water wastage in the concrete industry
