Use this CSI 3 part SimpleSpecs™ master specification to specify Portland Cement Terrazzo Flooring and base finishes.
Portland cement terrazzo floor and base finishes utilize sand, aggregates, and color pigments in a Portland cement matrix. Aggregates can be granite, marble, quartz, or other natural stone. Glass and other materials can be used as well.
Portland cement terrazzo is long-lasting and low maintenance and can be refinished several times.
Colors are achieved by varying the aggregates and color pigments. Patterns can be achieved by placing different terrazzo mixes between divider strips.
Portland cement terrazzo is placed as a wet mix over a sand or concrete substrate, then ground and polished after it sets to a smooth finish. Metal divider strips are placed prior to placing the wet terrazzo mix, to limit shrinkage cracking and to provide a decorative pattern.
For assistance in selecting, specifying, and detailing terrazzo refer to the National Terrazzo and Mosaic Association (NTMA) website at www.ntma.com.
