单组分碱激发胶凝材料的研究进展

Research Progress on One-part Alkali-Activated Cementitious Materials

碱激发胶凝材料(AACM)是普通硅酸盐水泥(OPC)的潜在替代品,可减少二氧化碳的排放,实现工业固废的综合利用。单组分碱激发胶凝材料(OP-AACM)有克服激发剂溶液的危险性、刺激性和腐蚀性方面的优势。综述了国内外关于OP-AACM的前驱体、激发剂、反应机理、力学性能与耐久性能等研究进展,并讨论和探索了OP-AACM面临的现实问题与尚需解决的问题。

Alkali-activated cementitious materials(AACM)are considered as a potential alternative to ordinary Portland cement(OPC),which can limit carbon dioxide emissions and help to achieve comprehensive utilization of industrial solid waste.One-part alkali excited gelling material(OP-AACM)has the advantage of overcoming the danger,irritation and corrosion of the activator solution.The study reviews the research progress on raw materials,activators,reaction mechanisms,mechanical properties,and durability OP-AACM at home and abroad;and discusses the current problems and future development prospects of OP-AACM.
