in the current study an experimental/statistical approach addressing key mechanical properties (compressive, tensile and flexural strength) and impact resistance of such new fibers with inclusion of different volume of polyphenylene sulfide (pps) fibers has been carried out on 288 specimens. results from this study revealed that compressive, tensile and flexural strength exhibit a good fit with...

This paper deals with the effect of fiber aspect ratio of steel fibers on shear strength of steel fiber reinforced concrete deep beams loaded with shear span to depth ratio less than two using the artificial neural network technique. The network model predicts reasonably good results when compared with the equation proposed by previous researchers. The parametric study invol...

The self-compacting concrete (SCC) was invented to overcome the compaction problems in deep sections, owing its perfect workability characteristics. Steel fibers when used with SCC would affect required fluidity characteristics but improve impact resistance. In this research, an experimental work conducted evaluate response of micro-steel fiber-reinforced SCC, under flexural impact. A 5.47 kg f...

in this paper, using numerical methods and test results, the behavior of reinforced concrete beams strengthened with fiber-reinforced polymers (frp) is investigated. in the numerical analysis, the concrete damaged plasticity model is used for considering the nonlinear behavior and strain softening of concrete. the abaqus finite element program is utilized for the analysis of 12 flexural beams s...

This study presents the experimental results about effects of Polyvinyl-alcohol (PVA) and Polypropylene (PP) fibers on fresh mechanical properties including compressive, splitting tensile strength, modulus rupture (MOR) as well toughness hybrid fiber reinforced self-compacting concrete (SCC). PVA PP were added into SCC mixtures having only macro steel also binary hybridization both micro fiber....

In this study, twenty glass fiber reinforced polymer (GFRP) reinforced concrete specimens were modelled using finite element method to predict the effect of GFRP compressive bars on the flexural strength and ductility of GFRP reinforced concrete beams. Also, the contribution of GFRP longitudinal rebars to the load-carrying capacity of reinforced concrete columns is determined. The concrete elas...

The huge quantity of concrete is consumed by the construction industry all over the world, probably second largest after water. In India, the conventional concrete is produced by using natural sand from riverbeds as fine aggregate. Dwindling sand resources poses the environmental problem and hence government restrictions on sand quarrying resulted in scarcity and significant increase in its cos...
