碱激发胶凝材料主要以硅铝质废弃物为原料,其能耗低、排放少,被称为低碳胶凝材料。该材料还拥有早期强度高、耐久性好等优异性能,被认为是一种具有广阔应用前景的新型胶凝材料。因此,随着近年对气候变暖的日益关注,碱激发胶凝材料的制备及应用技术成为绿色建筑材料领域的研究热点及前沿。1.碱激发胶凝材料的发展历史碱激发胶凝材料非常“年轻”。自上世纪40年代 Alkali-activated cementitious materials are mainly silicon aluminum waste as raw material, low energy consumption, less emissions, known as low-carbon cementitious material. The material also has high early strength, durability and other excellent performance, is considered to have a broad application prospects of the new cementitious material. Therefore, with the increasing concern about climate warming in recent years, the preparation and application of alkali-activated cementitious materials have become the research hotspots and frontiers in the field of green building materials. 1. History of Alkali-Activated Cementitious Materials History Alkali-activated cementitious materials are very “young”. Since the 40s of last century
