This paper investigates the torsional behavior of reactive powder concrete (RPC) beams using spiral reinforcement. The influences parameters, including different reinforcement configuration, ratio, and steel fiber content on performance nine RPC beams, were investigated discussed. experimental results showed that failure mode, ultimate torque, stiffness, energy dissipation not affected by longi...

In this research, 210 concrete cube specimens (15cm) were made replacing 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, and 60 percent of slag powder from Isfahan Steel Mill for cement. The control specimens were made with 350 kg/m3 cement content and the water cement ratio in all specimens was 0.51. The Slump value and compressive strength of concrete specimens in 7, 28 and 90 days were obtained and th...

Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

Abstract Suitable distribution of particles and the presence hydration lead to improved compressive performance optimum (even reduced) cost in production reactive powder concrete (RPC). This study was conducted obtain a better understanding RPC analyze behavior modified (MRPC) using properties surface resistivity, water penetration, strength, modulus elasticity, apart from cost. The present car...
