Individuals, including cement masons, segmental pavers and terrazzo workers, who work with concrete, a mixture of Portland cement, sand, gravel and water. Cement masons place and finish the concrete. They also may color concrete surfaces; expose aggregate (small stones) in walls and sidewalks; or fabricate concrete beams, columns and panels. Segmental pavers lay out, cut and install pavers (flat pieces of masonry usually made from compacted concrete or brick) that are used to pave paths, patios, playgrounds, driveways and steps. Pavers are manufactured in various textures and often interlock together to form an attractive pattern. Terrazzo workers create attractive walkways, floors, patios and panels by exposing marble chips and other fine aggregates on the surface of finished concrete.
