Precast concrete has many advantages for construction of buildings because of its strength and durability. It’s not only used in many construction applications, but it might actually date all the way back to Roman times. This primer about precast concrete can help you learn what it is, what construction applications it has, and the benefits of using it instead of other materials
Precast concrete might have started with the Roman Empire. In Rome itself, an extensive network of subterranean tunnels were built, many of which are still around today. Their existence seems to imply the usage of precast building elements.
The known history of what is known as precast concrete started in 20th century England. John Alexander Brodie was an engineer who found that precast concrete components were able to come together in making a structure. He first patented the process for precast concrete paneled structures.
Philadelphia’s Walnut Lane Memorial Bridge is often considered the start of the American precast concrete industry. Precast concrete happens off the actual construction site. A mold is used somewhere else to pour the concrete instead of on-site molding.
Precast concrete gets poured into a steel or wooden mold that has rebar or wire mesh. If necessary, the mold might have pre-stressed cable in it, too.
It gets cured under controlled circumstances, typically a plant. Once it is ready, it undergoes transport to its construction site where it is put into place.
Not all precast concrete gets pre-stressed using cable reinforcement. This is often done for structures needing more strength. Rebar or wire puts tension into the concrete, and that tension isn’t released until the curing is finished. It’s this release of tension that transfers strength into the concrete, making it even stronger than before.
When compared to standard concrete, precast materials have numerous advantages. To start with, it is often faster to cure. They can also be more economical and stronger than standard concrete.
Precast concrete’s versatility might be the most advantageous thing about it compared to standard concrete. Users who pick it get to enjoy a wide variety of textures, forms, and colors. It’s useful in the integration of facades, and it often meets the compatibility requirements associated with historical structures. Precast concrete can be useful for anything from small sections up to long and open spans. When it is no longer needed, precast concrete can be something that gets recycled or repurposed after it is removed or replaced.
Commercial and residential projects alike can be far more versatile in their planning and design. When precast concrete products show up on-site, they’re fully customized and ready for quick installation. Use them to expedite your project schedules and spend less money.
The advantages of precast concrete go past sheer convenience. Also consider these four advantages:
Precast concrete is known for versatility and durability, so many structures that have to withstand both weather and traffic might use it, including:
Buildings also use precast concrete for its sound-attenuating and fire-resistant properties. It also reduces moisture and engenders energy efficiency. For that, it might be used in buildings as varied as:
Whether you want to build something that’s been done before or something entirely new, precast concrete has many uses. However, you would need to choose a manufacturer for it. If you don’t choose a reputable manufacturer, then you will miss out on the benefits, but they also need to be able to handle the work you need done within your budget, specifications, and deadlines.
