Impact resistance and mechanical properties of High ...

High Strength Concrete (HSC) is an expression which is used to define a concrete with high performance and strength exceeds 40 MPa. The high elasticity or strength and low shrinkage and permeability are considered the main properties of the HSC. The aim of this study is to investigate the effect of High Reactivity Metakaolin (HRM) and/or Silica Fume (SF) on the properties of HSC.

This study evaluates the impact resistance and mechanical properties of a number of developed self-consolidating rubberized concrete (SCRC) mixtures reinforced with steel fibers (SFs). In this research, SFs were used to compensate for the reduction in tensile and flexural strength that resulted from adding high volumes of crumb rubber (CR).

Impact Resistance of Concrete Structures

We present simulations on the resistance of concrete structures due to impact loading. Therefore, a mesh-free method is exploited in combination with a viscous damage model that accounts for strain rate effects and high pressures that commonly occur in those events. In contrast to many other studies in the literature, we account for uncertainties in the material parameters by subjecting them ...
