Description

Vermiculite is a natural mineral from the mica group, formed mainly by iron and magnesium silicates. Extraction is carried out in open pit mines and then processed to separate rocks and impurities. The mineral is classified by size and subjected to a heat treatment, known as exfoliation, which allows the mineral to expand. This exfoliation capacity reaches up to 12 times its original volume.

Exfoliated Vermiculite is light, clean and has a high thermal and acoustic insulation value. In addition, it is non-combustible, insoluble in water and has the ability to absorb liquids.

Applications:

Exfoliated Vermiculite has a wide variety of applications, including:

Industry:

  • Creation of mortars and refractory elements.
  • Passive fire protection and mortar manufacturing.
  • In the steel and foundry industry, as padding for liquid metals.

Agriculture:

  • Excellent for covering seed trays, maintaining the temperature and humidity of the seed.
  • As a substrate, it can be mixed with organic substrates, providing a differentiated aeration capacity.
  • In animal nutrition, it is used to load a wide variety of nutrients, fatty acids, vitamins and antibiotics in the preparation of animal feed additives.
  • It has a pH in water of between 6 and 9, which makes it an excellent substrate in hydroponic crops.

Construction:

  • Basic ingredient in the production of lightened projection plasters.
  • Creation of vermiculite boards or plates, which provide fire resistance, insulation and thermal stability.

This versatility makes Exfoliated Vermiculite an essential product for numerous industries.

How much stone do I need?

How much stone do I need for the ground?

For shot and gravel song:
• ± 80kg per m², based on a 5cm layer.*For granulometries> 32mm a thicker layer is necessary.• Saca consumption: 1000kg = 0.625m³.
• Covering capacity: ± 12.5m² with a layer of 5 cm.

For pine cortex:
• ± 70L per m², based on a 5cm layer.
• Saca consumption: 1000L = ± 1m³ = ± 600kg
• Covering capacity: ± 14m² with a layer of 5 cm.

For volcanic, slate and chamota:
• ± 50kg per m², based on a 5cm layer.
• Saca consumption: 1000kg = ± 1m³
• Covering capacity: ± 20m² with a layer of 5 cm

How much stone do I need to fill a gabion?

Density of ± 1,650kg by 1m³.

The calculation is very simple to understand with an example, if you have a 100x50x30 cm gav. You have to make the following accounts:
1x0.5x0,3 = 0.15m³
0.15x1,650 = 247.50kg. stone.
*It is always good to calculate an extra 5%, since the gavions when filling them are a little and always enters some more stone than in the theoretical calculations.

Clarifications

ATTENTION!

Granulometries are sizes of sizes

Real sizes can vary slightly, since when talking, for example, 60-80mm stone, it means that the stones pass through a square mesh of 80x80mm. and do not go through a 60x60mm.
This 80x80 mesh can pass a 100mm stone. long and 65mm. wide so there may be a percentage of stones greater than 80 and less than 60mm.

Broken stones

On the other hand, in the stones of more than 60mm. There is a percentage of up to 10% stones that can be broken during classification, washing, loading and downloading, today we have no machinery that avoids those breaks.

In the photos you can see, only real products are seen, broken pieces have been removed.

Dust and sand in products

This product is not washed, so it contains dust, sand and even traces of other products due to processing and transport. This is not a problem when using it; The stone will be washed alone over time or can throw water before using it.
