ENVIRONMENTALLY FRIENDLY SOLUTIONS FOR THE DISPOSAL OF CONCRETE WASH WATER FROM READY MIXED CONCRETE OPERATIONS

Abstract

Disposal of waste water from Ready Mixed Concrete (RMC) operations is a great concern of the ready-mixed concrete producers. Most of the traditional disposal systems are no longer environmentally acceptable. Alternative solution is to recycle the waste water and use it as batch water to make fresh concrete. Research and the experience of the RMC industry indicate that the performance of concrete is not affected by the use of recycled water. Relatively new stabilizing admixtures also are being used to reduce wastes from batch plant operations.
