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.

SAP2000 structural analysis software is used to designed two of 500kV partially prestressed reactive powder concrete pole cross arm; moreover, poles of the two cross arm program have been compared. The results show that the triangular truss cross arm has good mechanical properties, improving the main mate’rial of the stress state, the pole reduced height 10m, by the analysis of the structure shows, this cross arm has higher reliability under the operating conditions, which can be used in 500kV transmission line; from economic and technical performance, the pole cost of this program is greatly reduced, while speeding up the construction progress and improving the comprehensive benefits of the poles in the transmission line.

In order to get mechanical properties ,some RPC samples with 5% steel fiber are tested, many groups data were obtained such as compressive strength, shear strength and fracture toughness. And a group of tests on RPC with 5% steel-fiber under penetration were also conducted to validate the performance to impact. The penetration tests are carried out by the semi-AP projectiles with the diameter of 57 mm and earth penetrators with the diameter of 80 mm, and velocities of the two kinds of projectiles are 300~600 m/s and 800~900 m/s, respectively. By contrast between the experimental data and the calculation results of C30 reinforced concrete by using experiential formula under penetration, it shows that the resistance of steel-fiber RPC to penetration is 3 times as that of general C30 reinforced concrete.
