  1. Eight concrete samples of different compound ratio of artificial lightweight aggregate ( coarse aggregate of expanded shale ) and ordinary aggregate, water - reducing admixture, expanding admixture, etc, are compounded firstly, based on the research of main properties such as agitating property, strength, dry surface density and deformation, an optimum compound ratio of the concrete with high strength ( cl40 ), light density ( 1800 ) and slight expand is achieved

    首先,採用人造輕骨料(頁巖陶粒)及普通骨料,加入減水劑、膨脹劑等,配製出了八種不同配合比的輕骨料砼與普通砼,並對其和易性、強度、干表觀密度、變形等主要性能進行了試驗研究,得到了強度等級cl40 ,密度等級1800的輕骨料中高強度微膨脹砼最佳配合比。
