Abstract Reactive powder concrete (RPC) is a special type of with remarkable properties, particularly compressive strength. Some its main disadvantages include high cement and SF content, fine quartz preferred size 150 ?m - 600 ?m, low water-to- binder ratio. These characteristics increase the cost RPC production affect sustainable development. Because this, researchers have resorted to explori...

Composite concrete Filled Tubular Steel (CFT) members, which have excellent deformability due to the well-known confined and constrained interaction between steel tube concrete, largely been utilized as bridge piers or columns in high-rise buildings, resulting increased strength decreased column size. This study examined experimental performance of filled with reactive powder (RPC) under axial ...

A new expression for estimating the ultimate shear strength of steel fibers reinforced high concrete (SFRHSC) beams strengthened with CFRP strips based on previous researches is proposed in this research. The covers different characteristics and principal parameters such as compressive strength, span to effective depth ratio, volume fraction fibers, amount distribution, stiffness, deep beam eff...
