| 摘 要： | 研究了粉煤灰单掺、粉煤灰与矿渣双掺对再生骨料混凝土(RAC)弹性模量的影响,并初步探讨了其影响机理;建立了再生骨料混凝土弹性模量与立方体抗压强度的相关关系式。试验结果表明:粉煤灰单掺会降低再生骨料混凝土的弹性模量,粉煤灰与矿渣双掺对弹性模量的影响随两者组合比例不同而有显著差异。

| Abstract: | The effects of additions of fly ash and fly ash-slag on elastic modulus of recycled aggregate concrete(RAC) are discussed,and the mechanism of action is researched in this paper. An empirical equation describing the relationship of elastic modulus and compressive strength of RAC is obtained.The experiment results show that that the elastic modulus is reduced when fly ash only was added to RAC and present a significant difference with the rate of fly ash and slag content. |
