摘　　要：将同批次页岩陶粒按粒径1.18~2.36、2.36~4.75、4.75~9.5、9.5~13.2、13.2~16、16~20 mm筛分为6组,取各组陶粒平均值,研究各组陶粒平均粒径与混凝土工作性、表观密度、抗压强度、导热系数、蓄热系数、热惰性指标及软化系数之间的关系,试验结果表明:平均粒径与混凝土工作性、表观密度、抗压强度、热工性能及软化系数之间存在较高的相关性。The same batch of ceramsite were divided into six groups 1.18~2.36 mm,2.36~4.75 mm,4.75~9.5 mm,9.5~13.2 mm,13.2~16 mm and 16~20 mm.The average size of ceramsite in each group was taken to study the correlation between the average size of aggregate and the slump,apparent density,compressive strength,thermal conductivity,coefficient of thermal storage,thermal inertia index and softening coefficient of concrete.There is a high correlation between average particle size and workability,apparent density,compressive strength,thermal parameters and softening coefficient of concrete.
