説明
In this paper, the properties of fresh and hardened concrete containing “pulverized dry sludge (PDS)” as both a mineral admixture and a fine powder for high-fluidity concrete were investigated. The so-called pulverized dry sludge is a very fine powder with a Blaine specific surface area of 5,000-15,000 cm2/g made from sludge cake by a process of drying and crushing.<BR>It was found that when PDS is used as a part of cement such as mineral admixture, PDS has no harmful effects on hardened concrete although the dosage has sometimes to be limited to about 10% of the cement content because high content of PDS significantly increases the demand of mixing water. Experimental results on high-fluidity concrete showed that concrete containing up to 30 % of PDS content had a good performance in both fresh and hardened properties. This research shows the potential for the effective use of concrete sludge disposed from ready-mixed concrete plants.
