Sustainability: The cement in concrete is derived from heating limestone, which is a carbon-intensive process that creates gas emissions. However, slag cement, fly ash and silica fume — all industrial waste by-products that are carbon neutral — can replace more than 50 percent of the cement, reducing emissions and improving the concrete’s ecofriendliness.
The basics: Marble is a natural stone composed of calcium carbonate; it’s in the same stone family as limestone and travertine. Color variations occur in marble due to mineral impurities in the stone. Slabs, rather than tiles, are typically used for countertops, where the dramatic veining can be displayed.
