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。 -
To obtain high fluid structural lightweight aggregate concrete with good uniformity, it is necessary to limit the max grain size of lightweight aggregate to 20mm, cement content to 500kg / m ~ 3 and slump of concrete mixture to 260mm
要獲得均勻穩定的大流動性結構輕集料混凝土，陶粒的最大粒徑不宜超過20mm ，水泥用量不宜超過500kg / m ~ 3 ，拌和物坍落度宜小於260mm 。 -
In addition, vibration has great effects on uniformity of high fluid structural lightweight aggregate concrete. there is obvious separation of lightweight aggregate from mortar in mixture of high fluid structural lightweight aggregate concrete with slump of 220mm when vibrated for 10 minutes
此外，振動對大流動性輕集料混凝土的勻質性十分不利，對坍落度220mm左右的輕集料混凝土拌和物，振動時間超過10秒，就會出現明顯的分層現象。 -
We have been produced high fluid structural lightweight aggregate concrete which apparent density is 1800kg / m ~ 3 and 28d compressive strength is 50 ~ 60mpa by
對軸心抗壓強度、抗折強度、彈性模量和抗滲性能的檢測表明，所配混凝土具有良好的物理力學性能和耐久性。
