A novel geopolymer-based high-performance concrete (G-HPC) sandwich wall consisting of two G-HPC layers separated by a metallic tube core possessing high strength and lightweight structure was developed in this study. The contact blast tests with 1 kg TNT were subsequently conducted to explore the b...
