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.
Disadvantages: This surface will either keep you busy or cause you to embrace its timeless patina. It’s softer and more porous than granite, meaning it scratches and stains easily. Acidic foods cause surface etching (though the appearance of the etching can be lessened with a honed finish).
