Flexural Strength Enhancement of Lightweight Concrete Beams Using Carbon Fiber and Epoxy Resin

Year: 2025

Type: article

Abstract: The paper presents the effect of reinforcing aerated concrete and volcanic rock on flexural strength. The tests used a three-point flexural test on beams made of both materials and two types of reinforcement: an Epidian 5 epoxy resin coating and carbon fabric impregnated with the same resin. The carbon composite increased the strength of aerated concrete by 1940% and volcanic rock by 2633% compared to unreinforced samples. The resin alone improved the load-bearing capacity of the beams by aerated concrete 118% and volcanic rock 147%, respectively. The tests showed that the resin filled the pores of the porous materials, significantly increasing their flexural strength.
