Why Polypropylene Fibre Is Used In Concrete

Polypropylene is a form of synthetic fibres commonly used in concrete as a way to reduce potential cracking and generally improve the durability of this construction material. In order to use these fibres, you do not need to make any special modifications to the concrete or rely on different tools, making PP fibres an easy and even cost-effective way to enhance the material.

If you're interested in leveraging PP fibre to enhance your concrete, this short guide from Bisley company can help you learn everything you need to know about it.

How Does Polypropylene Affect Concrete?

Polypropylene fibres are popular concrete reinforcers because they are resistant to drying plastic shrinkage. These fibres are able to absorb energy and distribute the load of the concrete much more efficiently. This results in less concrete needed, and lower maintenance costs. These fibres are also lightweight, non-magnetic, and homogenous, and they can withstand corrosion really well, unlike steel fibres or wire mesh known to have these problems.

The fibres will essentially hold the concrete blend together, and slow down its settlement to reduce water bleeding. While bleeding will still happen, it will do so at a much slower rate, which slows down drying time

Additionally, PP fibres have a high thermal and chemical stability. Put together, all these properties of polypropylene fibres can yield impressive benefits for concrete:

• Increases strength of the concrete
• Reduces the risks of cracking or spalling
• Enhances the lifespan of the construction
• Improve concrete compressive strength
• It leads to safer, durable constructions
• Prevents the transfer of moisture, etc.

What to Look for in PP Fibre for Concrete

Contractors looking for PP fibres to enhance these construction materials should look for the right length of PP material. The longer the fibres are, the stronger the bond between the fibres and concrete is, leading to better results. Shorter fibres are perfectly fine for smaller or lighter construction materials, but long fibres are generally recommended for bigger projects.

Additionally, it's important to also choose the right amount of PP fibres to add to the concrete for optimal results.

Polypropylene fiber

Description

Polypropylene fiber

A manufactured fiber made from the polymers or copolymers of Polypropylene. In , Giulio Natta (Milan Polytechnic, Italy) polymerized propylene and by polypropylene fibers were being commercially produced by Montecatini Societa Generale (Italy). Polypropylene fibers are lightweight, smooth and white with a slightly waxy feel. They are resistant to wear, crushing, acids, alkalis, moisture, fungi, and insects. Olefin fibers slowly degrade in sunlight and can be stained by oils. Polypropylene fibers are used to make rope, fishing nets, sewing threads, diaper covers, indoor-outdoor carpeting, artificial grass, upholstery fabrics, and stay-dry clothing. They are also used for geotextiles fabrics, pavement repair, roofing felts, and artificial ski slopes.
