An Investigation on Mechanical Properties and Bonding Strength of Polymer Concretes and Polymer Modified Concretes as Repair Overlays on Concrete Substrate

Selection, design and control of materials are very important for achievement of a compatible, durable and economical repair overlay. Suitable bonding of repair overlay to substrate and good resistance against fracture are basics for a durable overlay. Using Polymer Concretes (PC) and Polymer Modifi...
