Competitive advantages of AR Glass Fibers compared to iron meshes

 

There is no doubt that Fibratec glass fibers offer many competitive advantages against other products that are used to fullfil the same function in a concrete slab: ADDING FLEXURAL STRENGTH TO THE SLAB by DISTRIBUTING THE LOADS CORRECTLY. 

In this section, we will try to summarize some of the most sigificant advantages of AR glass fibers compared to STEEL meshes:

 

 


  • Steel meshe is typically sold in big formats. This makes necessary cutting and adapting these steel plates to the surface we need to cover with concrete slab. Additionally to this work, we have to consider the need to transport these plates by truck to the job side.

The glass fiber can be transported comfortably in sacs or paper bags in any vehicle. We just add it into concrete mixer as the last component and in a few minutes it is ready to pour down to the floor. Our concrete slab is already protected against cracking.

  • You need to use a wedge in order to elevate the steel mesh from the floor and place it in the middle of the concrete slab. Most of the times, steel meshes are being placed directly on the ground or are stepped on by the truck or the workers and therefore deformed. Additionally, the steel mesh plates should be tide together in order to ensure they will not move after concrete is pored on their top. This carries on a huge labor cost and long time of execution.

Glass fibers are simply added into concrete mixer at a velocity of 2 kg per minute either in a portable concrete mixer, concrete mixing truck or in the mixing plant. Once done, we just pour the concrete on the floor without the need of any extra work, nor additional manpower. We can save huge amount of time in execution.

  • When we need to build a 7 or 8 cm thick slab, we cannot put any steel mesh since this thickness is already too small to allow us doing so. Thus, we may have many cracking problems in this case.
Using glass fibers, we can even make 4 cm thick concrete slabs and yet have a good protection against cracking. 
  • The steel meshes may rust by water infiltration through the joints, that will  cause lost of much of its effectiveness to improve flexural strength of the concrete slab.
Alkali resistant glass fibers are made of glass. Therefore, they have no reactions with almost any of the chemical substances that we can find on a concrete floor, nor in any concrete additives or the ground. It even resists the most aggressive acid attacks.
  • A steel mesh cannot protect the ins and outs of a surface to be covered with concrete. It cannot reach round ends of a parking zone, cannot protect properly the edges of the slab or the manholes. Additionally, when we have a soil with difference in height and we need to level it using concrete for building a horizontal slab, use of fibers is perfect. We wouldn't really know where and how to place the steel mesh.
FIBRATEC glass fiber is simply in every cm3 of the concrete  slab, regardless the height or the shape of the área covered.
  •  Steel prices are very unstable. Therefore cost calculation for building concrete slabs using Steel meshes may not be very accurate in some projects.

Glass fiber prices are much more stable and overall cost for a concrete slab may cost at least 20% cheaper using FIBRATEC compared to steel meshes.
