Reusing of treated waste water in concrete production

Abstract

This project was conducted to study the possibility of usage of treated waste water in concrete production, so that the shortage and cost using potable water can be greatly reduced and the waste water can be suitably disposed for safe guarding the environment at the concrete batching plant. Grade 30 and Grade 35 concrete mix design were prepared using Ordinary Portland Cement using potable water and treated waste water produce from paper recycling factory (which is treated in a facultative pond) were tested to determine the mechanical properties of concrete. Among the test conducted are slump test, slump retention, compressive strength and setting time for laboratory mix concrete and plant batching mix concrete. The concrete mix designs were mixed at the laboratory using a drum mixer and also batched at concrete batching plant further ascertain the various in laboratory and plant mix concrete. The research shows that treated waste water from the paper recycling factory which had been treated in the facultative pond qualifies and can be used in making concrete.
