再生骨料掺量与硅灰添加量对再生骨料混凝土性能影响的研究

Study on the Influence of Recycled Aggregate Content and Silica Fume Content on the Performance of Recycled Aggregate Concrete

摘要: 本研究通过实验深入探究再生骨料掺量与硅灰添加量对再生骨料混凝土抗压强度、抗拉强度、粘结强度和孔隙率的影响。实验结果表明，再生骨料掺量增加会降低混凝土抗压、抗拉、粘结强度并增大孔隙率，而适量添加硅灰可有效改善这些性能。研究成果为再生骨料混凝土在实际工程中的合理应用提供重要参考依据。

Abstract: In this study, the effects of recycled aggregate content and silica fume content on compressive strength, tensile strength, bond strength and porosity of recycled aggregate concrete were investigated. The experimental results show that the compressive strength, tensile strength and bond strength of concrete can be decreased and the porosity can be increased with the increase of recycled aggregate content, and the appropriate addition of silica fume can effectively improve these properties. The research results provide an important reference for the rational application of recycled aggregate concrete in practical engineering.
