| 摘 要： | 陶粒吸水返水特性对混凝土的力学性能有重要影响。文章采用两种不同程度的预湿陶粒配制混凝土，进行立方体抗压实验、立方体劈拉实验、长方体弹性模量试验。试验结果表明：陶粒的孔隙率大小直接影响着陶粒的预湿程度和吸水率，吸水率大的陶粒会导致混凝土实际水灰比增大，降低了混凝土抗压强度，但劈拉强度和弹性模量变化趋势却不尽相同。 |
| 关 键 词： | 陶粒混凝土 抗压强度 劈拉强度 弹性模量 |

| Abstract: | The ceramic feature of water absorption and desorption have an important influence on the mechanical properties of concrete.In this study,the concrete with two different pre-wetted ceramsite had been put to the tests of cubic compression,and cubic splitting tensile,and rectangular elastic modulus.The results showed that the size of ceramic porosity directly affected the pre-wet degree and the water absorption rate;and high water absorption of ceramsite increased the actual water-cement ratio,and reduced the concrete compres-sive strength;but the trends of splitting tensile strength and elastic modulus were not totally the same. |
| Keywords: | ceramsite concrete compressive strength splitting tensile strength elastic modulus |
