摘要: A novel protective covering with a layered and staggered structure was proposed to protect concrete against projectile impact. Experimental study conducted investigate the ballistic behaviour of targets 12.7 mm armour-piercing incendiary at velocities ranging from 537.7 596.5 m/s. The results showed that exhibited superior integrity no damage on distal surface, whereas without were fractured penetrating cracks throughout thickness target. Moreover, protected displayed significantly reduced penetration depth compared covering. epoxy adhesive interlayers had bigger protection factor than silicone sealant interlayers, but former suffered more severe latter.
