Research on penetration resistance of ultra-high strength rock-filled concrete
This article studied the penetration resistance of ultra-high strength rock-filled concrete against the semi-armour piercing projectile of 2 000 lb by developing C120 ultra-high strength rock-filled concrete.It con-ducted numerical simulations and target tests of the penetration resistance of C120 ultra-high strength rock-filled concrete,analyzed the penetration depth of the simulations and tests,and calculated the penetration coefficient of C120 ultra-high strength rock-filled concrete by using the modified Berezan penetration depth formula.By compa-ring the concrete penetration coefficient,the penetration resistance of ultra-high strength rock-filled concrete is proved to be better than the concrete materials of same strength.
