Dune Sand Mortar Effects on Deflections of Repaired Steel Bars-Reinforced Concrete Beams
Abstract
This paper presents theoretical and experimental investigations to analyze the flexural
behavior of reinforced concrete beams repaired with mortars based on dune sands. The
beams supposedly damaged were repaired using mortars based on dune sand varying
the mortar cover thickness and the reinforcement ratio. After a suitable cure of beam
specimens in the laboratory, they submitted to progressive loading until failure. The
results obtained show that the repaired dune sand mortar could be used to enhance the
flexural capacity and the ductility of damaged reinforced concrete beams, repaired with
dune sand mortars. Comparisons between theoretical and experimental results in terms
of deflections are also presented.
