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
