Performances of SBR Latex Modified Ferrocement for Repairing Reinforced Concrete Beams

The use of ferrocement is a promising technology for increasing the flexural strength of deficient reinforced concrete members. The study reported herein investigates the mechanical properties of mortar through difference in polymer content and also by ferrocement with three different volume fractions of mesh reinforcement incorporated by Styrene Butadiene Rubber Latex. Consequently in order to exercise proper quality control from materials point of view, the ferrocement specimens being intended from Ferrocement Model Code and in addition to that the results were checked through the limitations of relevant code. Eight full-size beams, (two control beams and six strengthened beams) tested with different loading conditions and the variables were examined through the flexural test of the rehabilitated beams by the methods of attachment of mesh among various volume fractions with the influence of polymer modification on the properties of cement mortar. Performance of the tested beams and modes of failure are presented and discussed in this paper. The test results confirm that polymer modified ferrocement laminates can be used to significantly increase the flexural capacity of RC beams, with efficiency that varies depending on the tested variables
