| Research Abstract |
Almost all infrastructures are made of concrete so that concrete is very important structural material. In ready-mixed concrete plants where concrete is produced, a lots of dirty water so called sludge water is produced resulting from washing mixer, agitator truck ,etc. Sludge water should be separated into solid and water, in order to dispose of wastes. Recently, effective utilization of natural resources and environment-friendly materials and environmental preservation have been promoting as a national policy. In order to achieving the policy, the most effective means is the completion of zero-emission from ready-mixed concrete plants. Industrial by-product should be reuse in the original situation and in the original shape, then it is expected leading to restraint of cost for disposal and transportation, in addition energy consumption and CO_2 emission.
