Abstract
Being well recognized in repair, rehabilitation and maintenance of concrete structures, polymer
modified concretes are new high-performance materials. The present study was focused on the
availability and use of polymer-modified concrete under local conditions in Pakistan. Various polymer
compositions with subsidiary chemicals were prepared in the laboratory, and their feasibility in the
repair of structures was experimentally verified. The results demonstrated that the tensile strength of the
polymer-modified concrete, made with altered PVA emulsion, was three times more than the ordinary
concrete. Polymer-modified concrete with altered PVA emulsion showed excellent bonding with old
concrete. Furthermore, the above combination was highly cost efficient when compared to the use of
PVA emulsion.
