BEHAVIOUR OF CONCRETE WITH TREATED SEWAGE WATER

Abstract

This paper represents the experimental investigation of finding the feasibility of using treated effluent as a agent in concrete mix. This scope of study is restricted to only plain concrete cement without reinforcement. Brackish water collected from the residential building is effectively treated in treatment plants. The main objective of this project is to control the abundant use of drinking water in construction activities by implementing treated sewage effluent as mixing agent in concrete mix, curing and for other activities. This is perfectly suitable for arid areas where there is a shortage of rainfall and lack of natural resources. In that type of situation treated effluent is the best substitute to drinking water in concrete mix. This treated effluent can be directly used in concrete mix when it satisfies standards. Water sample of treated waste water is collected and tested and analyzed along with chemical parameters
were within the ASTM standards limits and can be used satisfactorily in concrete mixing. By using treated effluent in place of freshwater, not only saved natural resources but also enhanced the compressive strength of concrete up to 0.97%, 0.05%, 0.40% at curing ages of 7,14 and 28 days.
