In this study, a novel green construction material, high performance alkali-activated geopolymer concrete is introduced. Both numerically and experimentally investigations were conducted on a new type of structural slabs made of steel wire mesh reinforced geopolymer concrete against close-in ground surface explosion. Steel rebar reinforced conventional concrete slabs are also studied to compare the results. The experimental investigation was conducted to study the slab damage mechanism. It is found that the steel wire mesh reinforced geopolymer concrete slab showed less damage and fragmentation under 50 kg Trinitrotoluene (TNT) blast load within 3 m, 5 m and 7 m distances as compared to the C30 concrete slab. Numerical analysis was then conducted to further investigate the slab dynamic responses. Combining the steel wire mesh reinforcement with geopolymer concrete can help increase the blast resistance capacity leading to promising and environmental friendly structural protective design.

在这项研究中，介绍了一种新型的绿色建筑材料，高性能碱活化地聚合物。在一种新型的由钢丝网增强的地质聚合物制成的结构平板上进行了近距离地面爆炸的数值和实验研究。还研究了钢筋混凝土常规混凝土板，以比较结果。进行了实验研究，以研究板坯的损伤机理。结果发现，与C30混凝土板相比，钢丝网增强的地质聚合物混凝土板在50 kg三硝基甲苯（TNT）爆炸载荷下3 m，5 m和7 m距离内显示出更少的破坏和破碎。然后进行了数值分析，以进一步研究板坯的动力响应。
