 Abstract
Recently, The sludge water of ready mixed concrete has been investigated because of environmental pollution and disposal cost. So, sludge water is partially reused as mixing water. However, if sludge water is reused too much that would influence the qualify of concrete. KS specification limits the amount of sludge content up to 3% of cement weight. In this study, the effect of ready mixed concrete sludge on the characteristics of concrete is compared to raise the reuse ratio of sludge of ready mixed concrete. According to this experiment results, as blending ratio of re-mi-con sludge increases, workability is decreases. However, the sludge of ready mixed concrete water have a positive effect on the strength development. The drying shrinkage and the resistance of freezing and thawing have a minor effect.
