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.

Polymer concrete is a developed combined substance with greater characteristics in contrast with traditional concrete for example greater mechanical strength and chemical resistance. The aim of this paper is to investigate some properties of polymer concrete with and without waste glass as an aggregate. The waste glass was prepared and combined with different proportions of traditional sand. The mechanical properties (compressive strength, splitting tensile strength and flexural strength) were experimentally determined. The polymer concrete containing crushing waste glass was compared with polymer concrete containing normal fine aggregates. It was found that the waste glass could be used to produce polymer concrete and also is suitable for environment. This study concluded that 22% resin 78% fine aggregate of the total weight of mixture provides for the optimum distribution of fine aggregate, for that reason the best resin to fine aggregate ratio was chosen. The aggregate in polymer concrete was replaced with 5%, 10%, 15%, and 20% by weight of waste glass. It was also found that the compressive strength, flexural and tensile strengths of polymer concrete containing waste glass aggregate increases as the waste glass aggregate content increases.
