The Effect of Aggregate Properties on Concrete

The compressive aggregate strength is an important factor in the selection of aggregate. When determining the strength of normal concrete, most concrete aggregates are several times stronger than the other components in concrete and therefore not a factor in the strength of normal strength concrete.

Effect Of Clayey Particles And Organic Matter

Jun 10, 2021  • Presence of dust (silt and clay) in aggregates can reduce the compressive strength of concrete by as much as 52% at 30% content and as much as 57% at 52% content. This result shows that significant increase in dust content has minimal impact on the percentage reduction of concrete compressive strength.

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 ...
