Abstract

Ferrocement is a composite construction material which consists of high performance mortar and meshes. Ferrocement is a good technique in the field of strengthening of existing structural members. However, there is a chance for corrosion of steel meshes used for ferrocement, since the cover thickness is very less. In the present study, SBR latex modified ferrocement technique was introduced for the laminate preparation and the results were compared with normal ferrocement. In this work, Styrene - Butadiene Rubber (SBR) polymer was added to the mortar to increase the strengthening performance and to avoid the corrosion. Six numbers of ferrocement laminate were cast and tested in the laboratory, out of which three ferrocement laminates with SBR latex and remaining three are ferro-cement laminate without SBR latex (normal ferrocement laminate). The sizes of laminates are 550 mm length, 150 mm width and 20 mm thickness. All the laminates were tested under a two point loading system. The ferro-cement laminate with SBR latex shows better strength and improved flexural capacity compared to the normal ferrocement. The experimental results proved that the development of strength, deformability and fracture properties of laminate with SBR latex were more when compared to conventional ferro-cement.
