Experimental Investigation on Dynamic Behavior of Ultra High Performance Composite Concrete with Kolsky Bar
Abstract
Cor-Tuf is ultra high performance composite concrete consisting of pozzolanic powder, fine aggregates and steel fibers. Its compressive strength is more than 200 MPa, five times larger than conventional concrete. We conducted compressive Kolsky bar experiments on Cor-Tuf to investigate the behavior of Cor-Tuf under dynamic loading. Considering the inhomogeneity of concrete, we used two types of samples with 19 and large 76 mm diameters. To see the effect of steel fibers to bulk properties of concrete, both samples with and without steel fibers were used. We found that the strength was affected by strain rate.
