High-performance fiber-reinforced cementitious composites ...

High-performance fiber-reinforced cementitious composites (HPFRCCs) are a group of fiber-reinforced cement-based composites which possess the unique ability to flex and self-strengthen before fracturing. This particular class of concrete was developed with the goal of solving the structural problems inherent with today's typical concrete, such as its tendency to fail in a brittle manner ...

6/2/2016 · Remembering that the w/c ratio is the dominant factor regarding concrete strength, it can be seen that for high w/c ratio (0.7) the shape, texture or grading of the aggregate has little effect on compressive strength in contrast to high strength (low w/c ratio) concretes, as observed by Donza et al. . The flow time is mainly defined by the ...
