Development of Economical Polymer-modified Concrete for Repair of Concrete Structures in Pakistan
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...
متن کاملBond Development Between Carbon Fiber Reinforced Polymers and Concrete
Carbon fiber reinforced polymer (CFRP) sheets can be externally bonded for retrofit of concrete structures, improving flexure and sheer strength in the concrete. The key to CFRP sheets is the bond to the concrete, as bond is the means to transfer stress between the tow sheet and the concrete. Experimentation has been conducted to test a current market fiber-resin system, and to develop a resin ...
متن کاملUse of Polymer Concrete in Construction
Polymer concrete (PC) is a composite material in which the binder consists entirely of a synthetic organic polymer. It is variously known as synthetic resin concrete, plastic resin concrete or simply resin concrete. Because the use of a polymer instead of Portland cement represents a substantial increase in cost, polymers should be used only in applications in which the higher cost can be justi...
متن کاملPolymer Impregnation of Concrete by Methyl Methacrylate and its Effects on Mechanical Properties and Corrosion of Steel in Concrete
Freezing and thawing resulting from the ingression of water into concrete causes cracking or spalling. Corrosive ions such as chloride or sulfate penetrate the concrete surface and eventually reach the reinforcing steel. This causes the steel to corrode. Because of the high maintenance and replacement costs, responsible officials should be increasingly concerned about the growing number...
متن کاملBond of reinforcement in polymer concrete
Polymer concrete, a composite material in which the binding material is some type of polymer, is being used more widely in the construction industry. Polymer concretes can also contain steel reinforcing rebars; therefore, the rate of adhesion between polymer concrete and reinforcing steel must be determined. Our study investigated the extent and behaviour of adhesion in the case of reinforcing ...
