为实现工业废料的二次利用，将电石渣部分替代粉煤灰掺入碱激发粉煤灰-矿渣(AAFS)中，制备碱激发粉煤灰-矿渣-电石渣复合凝胶材料(AAFSC)。本文考察了不同电石渣掺量下AAFSC的抗碳化性能，并通过压汞测试、热重分析、X射线衍射仪和扫描电子显微镜等分析材料的微观结构。结果表明：经快速碳化作用，AAFSC的孔隙结构会向有害孔发展，抗压强度明显衰减；AAFSC在碳化前中期的抗碳化性能优于AAFS，但随碳化龄期延长，这种优势逐渐减小甚至消失；试验推荐的电石渣掺量质量分数为6%，此时AAFSC在碳化前中期具备最佳抗碳化性能，且在碳化后期仍具有最大抗压强度39.92 MPa；随电石渣掺量增加，AAFSC中Ca(...

To achieve the secondary utilization of industrial waste,alkali-activated fly ash-slag composite gel material(AAFSC)was prepared by partially replacing fly ash with carbide slag and mixing it into alkali-activated fly ash-slag(AAFS).The carbonization resistance of AAFSC...MORE To achieve the secondary utilization of industrial waste,alkali-activated fly ash-slag composite gel material(AAFSC)was prepared by partially replacing fly ash with carbide slag and mixing it into alkali-activated fly ash-slag(AAFS).The carbonization resistance of AAFSC with different carbide slag content was investigate...
