Possibilities of Increasing the Durability of Concrete Products by Technologies Based on Surface Hardening

Abstract:

Requirements of the quality of surface have increased recently for vibro-pressed concrete elements. As a consequence, there are new concrete products available with specially treated visual side - surface is coated with an impregnating paint and then hardened by infrared or ultraviolet light.The paper summarizes current knowledge of vibro-pressed concrete elements with surface treated in mentioned way. The focus is on description and effectiveness of individual methods, hardening principles and further possible treatments of surface of concrete aiming at higher durability of concrete. Observed parameters and properties of vibro-pressed concrete elements include resistance of surface to water and chemical de-icers, water absorbing capacity, resistance to wear, slip resistance and reduction of risk of efflorescence.
