Alkali-activated concrete (AAC) has attracted considerable attention since its first use as an alternative material to the well-known traditional Portland cement concrete (PCC) due to their superior properties and environmental impact. In this paper, a comprehensive review on the present knowledge about the AAC in terms of historical background, environmental impact, constituent materials and characteristics of alkali-activated slag concrete (AASC) is presented. The following topics are reviewed in details for AASC: historical background, environmental impact, constituent materials, reactions mechanism, hydration products, compressive strength, stress–strain behavior, elasticity modulus, Poisson’s ratio, tensile strength, bond characteristics with reinforcing steel bars and behavior under elevated temperature. Most studies have demonstrated the superior mechanical properties of AASC and their applicability in the construction engineering field. Moreover, AASC exhibits bond performance and elevated temperature resistance better than PCC. However, the review reveals that more studies and investigations related to mix design including mix proportions, mixing procedures and curing regime, with which the AASC could demonstrate the best engineering properties, are required.

碱活化混凝土 (AAC) 自首次用作著名的传统波特兰水泥混凝土 (PCC) 的替代材料以来，因其优异的性能和环境影响而备受关注。在本文中，从历史背景、环境影响、组成材料和碱活化矿渣混凝土 (AASC) 的特性方面对 AAC 的现有知识进行了全面回顾。AASC 详细回顾了以下主题：历史背景、环境影响、组成材料、反应机制、水化产物、抗压强度、应力应变行为、弹性模量、泊松比、抗拉强度、与钢筋的结合特性和行为在高温下。大多数研究已经证明了 AASC 的优越机械性能及其在建筑工程领域的适用性。此外，AASC 表现出比 PCC 更好的粘合性能和耐高温性。然而，审查表明需要更多与混合设计相关的研究和调查，包括混合比例、混合程序和固化制度，AASC 可以通过这些研究和调查来证明最佳的工程性能。
