A critical analysis of feasibility of mixing waste water in cement mortar and concrete

Abstract

The aim of this paper is to find the probability of using wastewater obtained from water plants situated in private structures. For the purpose of case study water treatment plants are selected in the region of Kankipaduof Krishna District of Andhra Pradesh. Each plant produces about 3600 to 4100 L/day water is being sold to the consumers of the area. Each plant is producing about 67% of wastewater in this process. Hence 91,500 lts/day is generating as waste water in the municipality region. All plants extract ground water for production and then treat them through Reverse Osmosis Process. The waste water so generated is drained off. Physical and chemical investigation were carried out on 14 water treatment plants. Out of which 10 typical plants were selected namely ChaitanyaJunior College (CC), Punadipadu (PC) area, Near Shivalayam (SC) and Bank colony (BC),in view of the convergences of constituent's in wastewater investigated by chemical and physical examinations. Performance of chose wastewater plants on the properties for example setting times, flexural strength, and compressive strength of OPC were performed in lab and contrasted them with test specimens using Distilled Water as blending water. No noteworthy changes were seen in the initial setting time yet considerable change has seen in the final setting time. Concrete properties like Slump & Density had notinfluenced by mixing water [2]. No major change has observed in compressive strengths (90 days) in four selected plants contrastedwith that of test specimens. The XRD was carried out to observe the main compounds in the hydration process.
