Polymer Concrete-Reinforced Concrete Composite Beams
Composite beams consisting of reingorced concrete and a layer or cap of polyester-concrete in the region of high compressive stress are tested and evaluated. The creep characteristics of polyester concrete were evaluated using 1000 hour creep tests, and the effect of sustained load on the ultimate compressive strength was also determined. Composite beams which were 6 by 6.5 by 64 in. (15.2 by 16.5 by 162.6 cm) were fabricated by capping precast reinforced concrete beams with a layer of fibrous polyester concrete of various given thicknesses. The composite beams were subjected to third-point loads on a simply supported length of 57 inches (145 cm). Load-deflection behavior and ultimate strength were determined for various combinations of reinforcement and depth of fibrous polyester concrete cap. Experimental and analytical results indicate that the fibrous polyester concrete composite beams are performance and material cost effective relative to reinforced concrete beams with the same percentage of tensile reinformcement.
