Abstract:

Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC). Polymeric binders are usually two component systems, one component containing the polymer and the second component a chemical capable of reacting with the polymer. Once the two components are mixed the ensuing chemical reaction converts the polymer into large molecules which bind the inert aggregates into a strong and dense composite. PC, can be formulated into high or low modulus, high strength concrete with good abrasion, wear, chemical and environment resistance. Cast-in-place PC is used in structural applications as an adhesive for new to old concrete, prefabricated bridge segments, anchor bolting and structural bonding.
