Wire mesh and rebar are roughly the same strength ; 55,000 psi yield ( both are available in various grades ). The concrete is shrinking away from each individual cut and in on itself. Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers – each of which lend varying properties to the concrete. At those scales, this option’s price can be managed well while still allowing you access to its enhanced level of tensile strength. In my experience, it is useless. So what is fiber mesh and what’s it for? The fibers show up at the surface and can look a bit funky. I love this blog.

The second thing WWF does is to keep two sections of concrete that are divided by a crack in the same plane (meaning that one won’t sink while the other sticks up). All concrete shrinks. As such, it cannot be used in all load-bearing projects. Many contractors prefer to choose their materials based on cost. If the WWF is lying on the ground and is never lifted into the pour, it then is not very effective. Great post. The fiber mesh’s job is to help hold the concrete together in that initial drying phase only, and when it cures, does little to NOTHING to add to the strength of the concrete.

Wire mesh’s most noteworthy advantage is that it does not require supplemental welding or trying together. This, too, is one of the reasons it is only used on fairly small concrete placement jobs. the need to secure rods at joint points with ties. (Welded Wire Fabric).

But as they serve the same purpose, it is difficult to understand their differences.Both are steel materials but they differ in structures and types. In some cases, the use of a high-range water-reducing admixture (HRWRA) may be needed to improve workability. As it corrodes, steel rebar swells and increases the tensile load on the concrete, which begins to crack and spall, creating openings that lead to further and faster deterioration of the steel and concrete. My first response to home owners is “Turn and RUN from any contractor who tells you ALL you need is fiber mesh because it’s stronger than WWF”.
