| Abstract |
The purpose of this research is to increase the artistic value of the surface of the concrete. Using the smooth surfaces of acrylic boards as mold, the concrete slabs with similar smooth and reflective surfaces can be created. Then, using a laser engraving machine etches pictures and patterns into the surface of the concrete. The extreme temperature of the laser burns and creates breaks in the surface of the concrete. By placing the laser burns in a predetermined form or pattern, an image is etched onto the concrete. The advantages of using laser engraving as proposed to more conventional methods are its higher resolution, the speed of engraving, and its ease of use. The breaks in the surface of the concrete have a comparatively rougher surface to the surrounding surface, which provides a medium for coloring of the etched surface, accentuating the engraved image. The materials used for coloring include acrylic paints and colored powders. The coloring enhances the outward appearance of the concrete, thus increasing its practicality. |
