摘要:
ABSTRACT:
Cementitious material was prepared in the laboratory from a mixture of dewatered sludge and lime incinerated at high temperature. The effects of mixture compositions, burning temperatures and durations on chemical and physical properties, and compressive strengths of the material were examined. The effect of curing conditions on compressive strengths was also investigated. From the results, an optimum condition on the mixture composition, burning temperature and duration, and curing condition on the highest possible strength of the material was determined. The experimental results revealed that sludge could be used to produce cementlike material that would satisfy the strength requirements in the ASTM standard for masonry cement. However, the cement is found to be quick setting and exhibits high water demand. The results on chemical analysis, physical properties, and compressive strengths of the material are presented.
