Experimental Study of Hybrid Layer Effect for Prism under Bending, Shear and Torsion

Abstract

The composite concrete structure by adopting varied concrete characteristics that are systematized in the layered method, described (hybrid), the principal purpose for utilizing the hybrid mixture is to enhance the load-carrying function for the segment. Hybrid concrete sections maintain high compressive strength, ductile, high absorption energy and high tensile strength, these properties can be performed by installing two or more various types or strengths of mixture layers collectively so that every layer is employed to its best benefit. The results of (flexural, shear and torsion tests) on hybrid prism composed of two layers of different types of concrete are presented and discussed with the effect of different parameters and variables. Normal concrete layer combined with a layer of (high or ultra-high-strength concrete) with the effect of fiber. The purposes of the present investigation are: find the engineering properties of three concrete types, the effect of hybrid concrete with different concrete types at different layers of prisms with different parameters and variables tested under three types of testing (flexural, shear and torsion tests).
