【提要】  选用四种高强陶粒为粗骨料，在相同的配合比条件下，对陶粒混凝土性能进行试验研究。试验表明，陶粒混凝土强度随着陶粒表观密度的增大而提高，陶粒的形状对陶粒混凝土的强度也有影响，陶粒混凝土的应力应变全曲线形状与普通混凝土的基本一致。

Abstract:The experiments of ceramic concrete with four high intensity ceramic grains as coarse aggregates of concrete are performed under the same proportion of mixture. The results show that the strength of concrete increases with the rising of the apparent density of ceramic grains，the concrete strengths are different with the different shapes of the ceramic grain，and the stressstrain relationships of the ceramic concrete are similar with those of normal concrete.
Keywords:lightweight aggregate concrete；ceramic grain；component； apparent density
