Structural behaviour of reinforced concrete – beams Mohamed K. Ismail
Firstly, structural behaviour of reinforced concrete beams containing crumb rubber and steel fibres. Mohamed K. Ismail Faculty of Engineering and Applied Science, Memorial University of Newfoundland.

This paper presents experimental work to investigate the strength and cracking characteristics of optimised self-consolidating and vibrated rubberised concrete mixtures with/without steel fibres (SFs) using large-scale reinforced concrete beams. The test beams · were cast with varying percentages of crumb rubber. Also, he performed some design codes and published empirical equations evaluated in predicting the shear capacity and· first cracking moment of the tested beams.
Structural behaviour of reinforced concrete – beams Mohamed K. Ismail
The results showed that the inclusion of SFs could alleviate the reduction in the shear capacity. Also, first cracking moment that resulted from the addition of CR. In addition, combining CR contributed to developing sustainable concrete beams with high deformability. Additionally, reduced self-weight and improved shear capacity. From the data available in the literature, adding rubber to small-scale samples. (i.e. cubes, cylinders and prisms) appeared to boost their impact resistance, damping properties, energy dissipation and ductility, arid also reduced the self-weight of the· concrete. However, all the studies confirmed that the compressive and tensile strengths of these concrete composites were negatively affected by the inclusion of rubber
