Abstract Reinforced concrete building materials were implemented a large scale development in recent years. Many of industrial materials have evolved with the development of construction industry such as steel slag (by product material) and fiber reinforced polymers (non-corrosion reinforcement). With the combination between a by-product aggregate and non-corrosion reinforcement it can be offer a cost effective reinforced concrete section that can achieve very high compression, flexure strength and very high durability against corrosion. This study presents experimental and numerical analysis of the flexural behavior of concrete beams with steel slag - obtained by the melting of steel scrap in the electrical arc furnace - as a coarse aggregate partial replacement, and reinforced by locally produced glass fiber reinforced polymers (GFRP) bars produced by pultrusion process as a solution to overcome the corrosion problem. Groups of 10 experimental beams were cast and tested up to failure under two-point load with 600 mm apart. All beams had the same dimensions with width, depth, total length and clear span between two supports were 100mm, 200mm, 2000mm and 1800mm, respectively. A numerical analysis program (ANSYS) was used to develop verification model for simulation of the behavior of experimental beam to give confidence in the use of ANSYS. Series of 16 beams models with different parameters (flexure reinforcement ratio, compression reinforcement ratio and shear reinforcement) were used to study how different parameters affect the behavior of a concrete beam with steel slag and investigate how GFRP bars should be applied in order to get maximum increase of load capacity. Experimental tests and numerical analysis results showed that adding steel slag to the concrete mixture as a coarse aggregate partial replacement, using GFRP bars and increasing of GFRP bottom main reinforcement ratio have a significant effect on the flexure behavior of the concrete beam by increasing load capacity. |
