Disadvantages: It’s not unusual for concrete, especially when cast in place, to develop tiny hairline cracks as a result of curing and settling. The cracks are typically not structural.
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.
