  • 摘要: 分析了超吸水性聚合物(SAP)的材料性能和SAP内养生混凝土配合比设计的关键参数,提出了内养生混凝土组成设计方法;从SAP吸释水行为和内养生混凝土水化特征角度,探讨了SAP内养生混凝土水分传输机制,综述了SAP内养生混凝土的收缩阻裂性能、力学性能和耐久性能;通过界面过渡区特征、水化产物和孔结构特征,探究了SAP内养生混凝土性能增强机理;总结了SAP内养生混凝土国内外工程应用情况,并展望了其未来的研究方向和应用前景。分析结果表明:SAP内养生原理为其本身的吸释水特性,但因SAP性能的差异和混凝土配合比等因素的不同,内养生水泥混凝土的各项性能有一定的差异性;SAP在渗透压和离子浓度的驱动下及时释水,补充混凝土内部水分丧失,降低早期水化热,并提升后期水化程度;SAP内养生混凝土的各项性能均受到其粒径、掺量和额外引水量的影响,在各参数均合适的条件下,SAP能够有效抑制混凝土的自收缩和干燥收缩,并增强混凝土的力学性能;SAP能够促进水化反应,生成更多的水化产物,填充混凝土的孔隙,增强混凝土的密实性,细化孔结构,切断连通孔隙,从而改善混凝土的抗冻、抗渗等耐久性能;SAP的再溶胀能力可阻塞混凝土裂缝,生成的CaCO3等水化产物可使混凝土裂缝自愈合;SAP内养生作用能够增强水泥石与集料之间的黏结性,减少甚至消除界面过渡区微裂缝,提高界面过渡区强度;SAP内养生水泥混凝土在桥梁桥面整体化层、横隔梁、湿接缝、桥墩及隧道二次衬砌等部位已成功应用,抗裂效果优良。
