Effect of Fiber, Cement, and Aggregate Type on Mechanical Properties of UHPC

Ultra-High Performance Concrete (UHPC) is a new class of concrete that differentiates itself from other materials due to its exceptional mechanical properties and durability. It has been used in structural rehabilitation accelerated bridge construction, precast applications, several applications the past decades. The UHPC include compressive strength greater than 124 MPa (18 ksi) sustained post cracking tensile 5 (0.72 when combined with steel, synthetic or organic fibers. Proprietary, pre-bagged mixtures are currently available market, but can cost about 20 times more traditional concrete. This high price unique mixing procedure required for limited widespread use US motivated many researchers develop economical versions using locally materials. objective this study was investigate effect different proportions typical mixture components on mixtures. Particle packing theory determine few optimal then modifications were made effect. A around achieved without any quartz particles design. Doi: 10.28991/cej-2021-03091726 Full Text: PDF
