Some mechanical behaviors were tested by investigations of compressive strength, and direct tensile, strength of reactive Powder concrete (RPC) containing recycled glass powder (RGP) as a supplementary, cementitious material. This study goals to survey the pozzolanic activity of recycled glass powder (RGP) up to (30%) silica fume replacement and its effect on the properties of recycled reactive powder concrete (RRPC) that made by waste glass (WG) and recycled fine concrete aggregate, which has not been investigated before. These properties contain compressive strength and direct tensile strength. Glass is principally composed of silica so that when waste glass is grind to micro particle size in RPC as a partial replacement of silica fume could be a substantial step to development of sustainable material. In this study, high strength reactive powder concrete (HSRPC) with mean compressive strength of 118.4 MPa at 28 days slightly decreased when 40% recycled fine concrete aggregate were used then the strength evolve afterward when 20% of waste glass powder WGP was utilized. The strength tests outcomes indicated that waste glass powder gave greater strength compared to ordinary reactive powder concrete. |
