Traditional concrete is produced by combining water, aggregate—a filler material such as sand or gravel—and Portland cement, a patented powder made of limestone, clay, and gypsum. However, you can also create specialty concrete mixtures using different ingredients. For instance, you can replace the Portland cement with fly ash, a byproduct of burning coal. Below, Builder's Concrete East, a specialty concrete supplier in Windham, CT, explains the advantages of using fly ash in ready-mix concrete.
4 Reasons to Use Fly Ash in Ready-Mix Concrete
Fly ash is essentially a waste product of combustion produced by coal-fired power plants, whereas Portland cement is a commercial product manufactured for profit. Because of this, fly ash is often less expensive while providing similar results.
2. Environmental Concerns
Because fly ash is a byproduct of energy production, its use in concrete products is considered more environmentally friendly than if it were simply to be discarded. Additionally, it requires less water than Portland cement and eliminates the greenhouse gases created during cement production.
Ready-mix cement containing fly ash is easier to work with. This becomes particularly noticeable during colder temperatures. Fly ash concrete is also more resistant to cold weather and fewer problems arise due to the freeze-thaw cycle.
Fly ash produces a denser concrete, which is less permeable by moisture and does not shrink. It results in sharper detail and a smoother surface while reducing cracking problems and bleeding.
Although fly ash offers several benefits when used in blocks, pavers, and ready-mix concrete, some smaller builders and contractors might not be familiar with these products and may even exhibit some resistance to their use.
