In order to study the anti-penetration mechanism of composite structures and influence foamed aluminum on performance structures, two were designed processed. Penetration tests carried out finite element models established correctness verified. The results show that has a cushioning effect can reduce ceramic damage. However, cannot provide support for deformation Kevlar, which leads shear damag...

Abstract This paper aims to investigate the feasibility of incorporation nanosilica (NS) in ultra-lightweight foamed concrete (ULFC), with an oven-dry density 350 kg/m 3 , regard its fresh and hardened characteristics. The performance various dosages NS, up 10 wt.-%, were examined. In addition, fly ash silica fume used as cement replacing materials, compare their influence on properties concret...
