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.
