CAN SYNTHETIC FIBERS BE THE RIGHT CHOICE FOR YOUR CONCRETE PROJECT?

“Producing the perfect concrete has become a kind of philosopher’s stone of the late 20th century.” – Iain Borden, Forty Ways to Think About Architecture: Architectural History and Theory Today

Centuries ago, ancient civilizations would use fibrous things such as straw and even horsehair in cement-based construction materials to create a composite material with increased toughness. Experts suggest that this concept is more than 4,500 years old. This technique would offer better resistance to cracking and an improved post-cracking response.

Just hearing the word “concrete” can evoke images of durability and strength. This sturdy white material is known for being one of the toughest construction materials out there. But like everything, there is room for improvement. Today, the concrete industry faces the same challenges as ancient civilizations had to face.

How can we use modern materials to bolster an even stronger concrete product?

With the wide use of Portland cement in today’s concrete, the industry has tried to reduce the cracks of finished concrete. Since the 1970’s there has been an increased interest in fiber and with the advances of testing equipment and analysis procedure. This was a major advantage for the concept of fiber, proving that it does enable an outstanding property of absorbing larger amounts of energy compared to ordinary Portland cement concrete.

Synthetic concrete fiber is a manmade material that consists of microfibers that can be made up of acrylic, nylon, polyester, and carbon. It is added to the mix after the batching process.

After mixing for 4 to 5 minutes, these fibers quickly distribute through the concrete and then help the concrete reduce plastic shrinkage cracks during the first 24 hours of placement. Shrinkage cracks are caused by a loss of moisture on the surface of the concrete. If you are looking to reduce cracking or other imperfections, these synthetic microfibers will improve the overall strength and help protect the concrete from stresses when it is most vulnerable.  

Because it builds a mix that is stronger and less susceptible to cracks, it is perfect for jobs that include patios, pathways, sidewalks, driveways, and foundations. Less plastic shrinkage will allow for a smooth surface.
