The wear characteristics of a glaze generated on the ordinary Portland cement (OPC) surface of concrete using a 2 kW high power diode laser (HPDL) and a 3 kW CO2 laser have been determined. Within both normal and corrosive environmental conditions, the wear rate of the CO2 and HPDL generated glazes were consistently higher than the untreated OPC surface of concrete. Life assessment testing revealed that surface glazing of the OPC with both the CO2 and the HPDL effected an increase in wear life of 1.3 to 17.7 times over an untreated OPC surface, depending upon the corrosive environment. The wear life and the wear rate of the HPDL glaze were found to be consistently higher than that of the CO2 laser glaze. This is due to the fact that the wavelengths at which both lasers emit at are very different and consequently, differences will exist between the CO2 and HPDL beam absorption characteristics of the OPC. Such differences are the cause of the distinct glaze characteristics which furnishing each microstructure with its own unique wear resistance characteristics.
