Purchase Portland cement to use as the mortar. Use Quikrete only if you are working on a small project such as a porch or steps. If the terrazzo concrete is for a large room, use regular Portland cement to allow you time to work with the terrazzo mix. Step 4. Combine the Portland cement and aggregate in a 1:2.5 or 1:3 ratio.

1.3 Portland cement. Portland cement is the basic ingredient of concrete, mortar and plaster which consists of a mixture of oxides of calcium, silicon and aluminum. Portland cement and similar materials are made by heating (about 1350–1400°C) limestone (a source of calcium) with clay and then grinding this product (called clinker) with a source of sulfate (most commonly gypsum).
