Abstract

There is renewed interest in using lasers to surface treat concrete from the architectural and civil engineering sectors, as well as the nuclear industry. CO2 laser, high power diode laser (HPDL) and fibre laser radiation were used to generate glazes on the ordinary Portland cement (OPC) surface of common concrete, and the effects thereof on the, physical and mechanical properties of the glazes were assessed. This investigation is useful in that the samples used were prepared in 1996 and 2011; thus giving a unique prolonged time perspective to the findings. This work has demonstrated that a durable glaze/surface seal can be produced on the OPC surface of concrete that is durable, long-lasting and is easily removable depending upon the laser used.
