Waste glass sludge as a partial cement replacement in mortar. J Kim admixture on biaxial flexural behavior of ultra-high-performance fiber-reinforced concrete.

In this study the efficiency of the use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) for the strengthening of existing Reinforced Concrete (RC) beams has been investigated. Experimental work has been conducted to determine UHPFRC material properties. Dog-bone shaped specimens have been tested under direct tensile loading, and standard cubes have been tested in compression. The first property listed, the ultimate tensile strength of 4.6 MPa, is slightly larger than the accepted tensile strength of standard fiber-reinforced concretes, (4.3 MPa).

Optimizing mix proportions of normal weight reactive powder concrete with strengths of 200350 MPa. Ultra-high-performance concrete (UHPC) is a relatively new class of advanced cementitious composite materials, which exhibits high compressive (above 21.7 ksi [150 MPa]) and tensile (above 0.72 structures’ service life. Ultra-high performance ﬁbre reinforced concrete (UHPFRC) may be an alternative for some structure types, especially in very aggressive environments, because it draws from the latest concrete industry developments to deliver high strength and durability. Although such concretes require large amounts of cement This research work analyses the influence of the use of by-products from a fluorite mine to replace the fine fraction of natural aggregates, on the properties of Ultra-High-Performance Fibre-Reinforced Concrete (UHPFRC). Replacing natural aggregates for different kinds of wastes is becoming common in concrete manufacturing and there are a number of studies into the use of waste from the Ultra-high-performance concrete. Ultra-high-performance concrete is a new type of concrete that is being developed by agencies concerned with infrastructure protection. UHPC is characterized by being a steel fibre-reinforced cement composite material with compressive strengths in excess of 150 MPa, up to and possibly exceeding 250 MPa. Superior performance was observed in terms of stiffness, yield & maximum strength, when three side UHPFRC jacket was used.
