Stones are usually known as the strongest building materials. But due to the possibility of an earthquake and other events affecting the strength of the structure, it is necessary to take measures to increase its strength and resistance. Especially when a type of stone is inherently soft and fragile, such as marble, which in most cases are soft and fragile. Like the black marble of Najaf Abad. For this purpose, to increase their strength, it is necessary to use a mesh behind the stone.
Because marble stones have limestone veins. Limestone veins are more common in Dehbid Chihark marble, which has many clay veins. Over time and in the process of processing, these veins may break apart and cause the stone to break and crumble. So these types of stones definitely need to be earthquake resistant with fiberglass mesh in the form of epoxy.
when the rock is extracted from the mines and transferred to the quarrying factories; Operations such as cutting, resin and epoxy, mesh behind the stone and final finishing are performed. This operation gives us marble that is much more resistant than before.
The advantages of installing a net behind the marble stone
- Increased compressive strength
- Increasing the strength and integrity of the stone
- Preventing crushing and breaking of stone during the installation, sub-assembly and transportation stages
- Increasing the adhesion of stone to mortar
- Prevent stone wear
- Generally increasing the life of the stone
- Increase tensile strength, bending
The selection of each type of processing steps depends on the type of stone. However, in general, in most building stones (except for granite), a mesh is used behind the stone to increase their strength and compressive strength.
The steps of installing the mesh behind the stone
when the stone cubes are extracted from the mines and transferred to the quarrying factories; Various processes are done on them, including gluing a net behind the stone.
This process is such that after cutting the stone cup in the desired thickness, a mesh layer is attached to the back of the stone using a special resin, which is also called stone mesh epoxy. This material adheres the fiberglass mesh well to the stone.
What kind of mesh should be behind the marble stone
The mesh behind marble is made of fiberglass or glass fibers. Fiberglass is a type of composite. Composite is a mineral material that consists of several other materials and has different characteristics from its constituent materials such as lower density and longer life. This product is made of polymer materials. which uses glass wool as a reinforcing material. Fiberglass mesh is a non-flammable material, it also has low weight and high resistance.
Types of fiberglass mesh
Fiberglass mesh has three types:
- Interior wall fiberglass mesh
- Exterior wall fiberglass mesh
- GRC reinforcing mesh
You can read more about them. And all three types are available in Soorin Baft.
Features of fiberglass mesh
Fiberglass mesh has special features that make it the best option for increasing stone strength:
- High tensile strength
- Resistant to moisture (waterproof) and chemicals
- Electrical insulation: Fiberglass is a good insulator against electricity, even at low thicknesses
- Non-flammable: Since fiberglass is a mineral, it is inherently non-flammable.
- Consistency of dimensions: Fiberglass does not change its size and dimensions under the influence of temperature and has a low coefficient of linear expansion.
- Resistant to decay: Fiberglass does not decay and is resistant to decay factors.
- Thermal insulation: Fiberglass has low thermal conductivity and is very useful in building
Applications of fiberglass mesh
It is interesting to know that this net is not only used to strengthen building stone; It also has many other uses. Among them are:
- In general, strengthening the stone facade (which is used during installation.)
- Strengthening the stone during processing
- Repairing cracks in concrete
- Making the structure anti-seismic
- In general, increasing the resistance and strength of building materials
- Creating a unified surface in plaster walls
