Abstract

Reactive powder concrete (The RPC) is a promising building material for the foreseeable future because of its benefits over other forms of concrete. However, neither the blending specifications neither the flexural members made from this material's mechanical strength is specified in any code. The goal of the current effort is to investigate the flexural, and shear strengths of RPC beams. Five groups of beams made with RPC are intended to investigate the maximum and service flexural and shear strengths. Three groups are designed to fail in flexure and two to fail in shear. According to experimental testing, it was found that experimental loads applied on beams were always higher than the theoretical load calculated using the equations of Japanese codes (20 – 30 %). It was also noted that the shear failure load was 5% to 22% higher than the theoretical load.
