Impact properties of geopolymeric concrete: a state-of-the-art review

Abstract

The application of geopolymer instead of cement in construction engineering provides an effective way to achieve sustainable development. A large number of studies have shown that geopolymeric concrete (GC) has excellent static performance. However, there are relatively few studies on the dynamic performance of GC which is of dominate importance in cases such as explosion, earthquake and other impact loads. This paper presents a brief review of recent research on the impact properties of GC, in order to facilitate the research development in this field. The effects of strain rate, fiber type, alkali type, elevated temperature, water environment and flow state on the impact resistance performance of GC were analysed. Research findings revealed that GC exhibited better impact properties than ordinary Portland concrete (OPC).
