  1. This paper deals with high fluid concrete in which high strength ceramsite made from shale was used as coarse aggregate. effects of cement content, water - cement ratio, sand percentage, mineral admixture, grading and pretreatment of lightweight aggregate on compressive strength and workability of high fluid structural lightweight aggregate concrete have been studied. the rules of water absorption of high strength lightweight aggregate under different pressure and effects on uniformity of high fluid structural lightweight aggregate concrete have been studied too

    本文採用高強頁巖陶粒,摻加高效減水劑配製大流動性結構輕集料混凝土,討論了水泥用量、水灰比、砂率、礦物摻料及輕集料的級配和預濕方式對大流動性結構輕集料混凝土強度和工作性的影響;系統研究了高強陶粒在常壓和壓力下的吸水規律;研究了影響大流動性結構輕集料混凝土勻質性的因素,提出了解決大流動性結構輕集料混凝土分層離析的具體措施。
