Crack propagation speed in ultra high performance concrete (UHPC) [PDF]

Construction and Building Materials, 2016
Abstract This paper investigates crack speed in ultra-high performance concrete (UHPC) using pre-notched three-point bending specimens. The experimental parameters are fiber volume fraction and rate of loading. A hydraulic servo-controlled testing machine is used to apply lower notch tip strain rates, in the range of 0.025–1.0 1/s, while a newly ...
