For typical concrete construction scenarios, steel rebar is an easy go-to choice. In a fiber reinforced slab system the concrete itself is manipulated. Concrete has a high, compressive strength meaning it can withstand vertical forces. When working with concrete you will be faced with 2 popular choices when reinforcing concrete.

Do some serious soil compaction. With 1/4 the weight of steel rebar, this product exceeds the requirements of ASTM D7957 Standard specifications for solid round glass fiber reinforced polymer bars for concrete reinforcing. Many areas still have building codes that require rebar.

To increase tensile strength, concrete can be reinforced with Fibermesh or rebar.

to a maximum of 75 mm (3 in. These cracks rarely occur in slabs-on-grade but will always occur on elevated slabs if not reinforced with rebar or welded wire fabric. fiberglass reinforced polymer rebar FRP Rebar is a Spiral Wrapped Structural Reinforcing Rod made from a combination of fiberglass roving and resin.

In drives, garage floors, patios, and walks I prefer 6x6x10x10 mesh (or whatever they changed the name to this week) and fiber reinforced concrete. I like the smaller grid for crack control. I did a lot of commercial work and it was always speced for rebar. Concrete with fiber and rebar reinforcement would cost little more than plain rebar and be even better. If flexural cracks do develop in slabs-on-grade, there is a problem with the subgrade.
The first is using rebar and the second is using steel mesh. This

If you have ever used a jackhammer to remove concrete with fiber in it, you know how tough it is compared to "regular" concrete.

Rebar vs. Wire mesh and fiber in concrete. Rusted new rebar versus unrusted GFRP form ties. Fibres are an ideal ingredient for improving the performance and durability of concrete and mortar.

).” (E-701Committee, 2006). I have googled the subject of wire mesh vs rebar and found there to be very few legitimate resources on this subject. Everything from buildings and homes are built on top of reinforced concrete slabs and even some gardens and pools will make use of it. It's usually a good idea to use it, but if you wet cure for a month, it doesn't do a whole lot. GFRP (Glass Fiber Reinforced Polymer) is an alternative material that has some inherent properties that can, in some cases, offer better performance over time – generally at a higher initial cost. A versatile mix, fiber-reinforced concrete can be used for on-ground floors and pavements, as well as construction parts like beams and pillars without the increased cost of using rebar. I would like some input on what some of you like to use in your concrete. Fiber-Reinforced-Concrete Beams Reinforced with FRP Rebars by H. Wang and A. Belarbi Synopsis: The main objective of this study was to develop a nonferrous hybrid reinforcement system for concrete bridge decks by using continuous fiber-reinforced-polymer (FRP) rebars and discrete randomly distributed polypropylene fibers.

I prefer the 6x6 mesh over bars because I feel the steel is more effectively spread out in the concrete. The fibers vary in size depending on the application, however, when setting a related standard, ACI considers, “Common lengths of discrete fibers range from 10 mm (3/8 in.)

Steel reinforced concrete is concrete that is reinforced by either metal reinforcement bar (rebar), wire mesh or some other kind of metal. Soil prep will be a big factor long term. The prime reason for using GFRP is for concrete longevity.

However, concrete is a very brittle substance and possess a low tensile strength or resistance to horizontal forces such as expansion or contraction.
Fiber reinforced concrete can replace steel mesh in many applications. With 1/4 the weight of steel rebar, this product exceeds the requirements of ASTM D7957 Standard specifications for solid round glass fiber reinforced polymer bars for concrete reinforcing. Fiber reinforcing is very good in restricting the initial shrinkage cracking that occurs in the initial stages.

The finite element (FE) analyses, was used to numerical modelling of the pull-out tests. Each strip was reinforced in the long direction with #5 bars spaced 8-1/2 inches on center, providing steel equal to 0.4% of the slab’s cross-sectional area.
