Abstract:
Pakistan is a country which has been mired with natural calamities such as
earthquake and flooding which not only have caused a great amount of loss
and suffering in terms of human life but also in terms of the damage to the
concrete infrastructure. An effective research is needed for the selection of
effective repair materials and effective repair techniques for the repair and
rehabilitation of the present infrastructure. Styrene Butadiene Rubber Latex
(SBR), Polyvinyl Acetate (PVA) and ZUBA (latex of various polymers) are the
polymers which have been introduced in this research to improve the overall
performance of the Plain Cement Concrete (PCC) when used as a repair
material. The mechanical properties of PCC repaired with different polymers as
described above were studied. This paper focuses on the mechanical
properties of concrete which has been repaired with polymer modified
mortars
