Description
Summary:In this work, the results of an experimental investigation on reinforced concrete by fiberglass honeycomb sandwich panel structures are presented. The experimental program included three beam specimens. Two of the beams were reinforced with different thicknesses of honeycomb structures. Flexural and uniaxial compression tests were performed. The tensile strength remains to be increases by a factor of 2.40 for compression and by 1.60 for flexion. The results obtained in terms of reinforcement are discussed. The changes are likely attributed to a modification of the adhesion forces at the honeycomb structures/concrete interface.
