Ductal UHPC Concrete Materials Victoria

Performance evaluation of continuity connections for use

Two different materials were tested for use as the longitudinal joint material, Ductal UHPC and Korean UHPC. Both materials had comparable results throughout testing. As for the transverse joints, the inclusion of the steel compression block showed to effectively alter the performance as the specimen was able to withstand a larger moment prior

A review on ultra high performance concrete: Part II

1. Introduction. Ultra high performance concrete (UHPC) could show compressive strength from 150 to 810 MPa , approximately 3-16 times as that of conventional concrete.With incorporation of steel fiber, the ductility and energy absorption of UHPC is typical 300 times greater than that of high performance concrete (HPC).
