High Velocity Impact Cement Breaker T2tph

Resistance of high-performance fiber-reinforced cement composites

As one of the most commonly used construction materials, concrete has been widely investigated for severe loading conditions such as impact and blast. In these investigations, the localized damage on concrete caused by high-velocity projectile impact (HVPI), especially the penetration depth, has always been a concern.

High velocity impact tests are conducted on ultra-high performance concrete targets. Impact responses of concrete targets and projectiles are analysed. Numerical studies are conducted and compared with tests. The test results of penetration depth are compared with the previously proposed model.

Ultra-high performance concrete subjected to high-velocity …

The K&C material model is widely used to numerically predict the responses of concrete structures against impact or blast loadings. In the literature, most of the K&C parameters are calibrated for normal strength concretes (NSCs), and are thus not directly applicable for ultra-high performance concretes (UHPCs).
