Reinforcing Concrete by Adding Fibers - The Concrete Network

Fibers can be added to the concrete mix in lieu of welded wire mesh. The problem with welded wire mesh is that it often ends up on the ground from being stepped on as the concrete is being placed (particularly if no support blocks are used). Another problem is that mesh does not prevent or minimize cracking-it simply holds cracks that have already occurred together.

Fiber-reinforced concrete - Wikipedia

Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers – each of which lend varying properties to the concrete. In addition, the character of fiber-reinforced concrete ...

Evaluating plastic shrinkage and permeability of ...

A significant reduction in crack generation, appearance period of first crack and crack area between plane concrete and fiber reinforced concretes was found. The experimental result with inclusion of 0.1–0.3% fiber in concrete indicated that plastic shrinkage cracks were reduced by 50–99% compared to the plain concrete.

How much fibermesh is added to concrete?

A. We use fibermesh in all the concrete floors and slabs we pour. We add 1 bag (usually 1lb.) of the micro polypropylene fibers to 1 yard of concrete. Most synthetic fibermesh products are engineered for use as concrete reinforcement at a ratio of 1.0 to 1.5 lbs per cubic yard (.60 to .90 kg per cubic meter). of concrete.

Concrete Reinforced with Polypropylene Fibers| Concrete ...

Polypropylene fibers tend to hold the concrete mix together. This slows the settlement of coarse aggregate and thus reduces the rate of bleeding. A slower rate of bleeding means a slower rate of drying and thus less plastic shrinkage cracking. In hardened concrete, polypropylene fibers act as crack …

Does Freshly Poured Concrete Normally Crack? | Angie's List

RELATED: Why Concrete Cracks and How to Prevent It. There are a number of reasons why concrete cracks. The most common is because concrete shrinks as the excess water evaporates and it hardens. Unfortunately, too often contractors add too much water to the mix, which makes it easier to apply but also more vulnerable to cracking.
