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 floor?

For boulders and gravel:
• ±80kg per m², based on a 5cm layer. *For grain sizes >32mm a thicker layer is necessary. • Consumption per bag: 1000kg = 0.625m³.
• Covering capacity: ±12.5m² with a layer of 5 cm.

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

For volcanic, slate and chamotte:
• ±50kg per m², based on a 5cm layer.
• Consumption per bag: 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 per 1m³.

The calculation is very easy to understand with an example, if you have a 100x50x30 cm gabion. you have to do the following accounts:
1x0.5x0.3= 0.15m³
0.15x1.650= 247.50kg. of stone.
*It is always good to calculate an extra 5%, since when the gabions are filled they widen a little and there is always a little more stone included than in the theoretical calculations.

Clarifications

ATTENTION!

Granulometries are sieve sizes

The actual sizes may vary slightly, since when we talk about a 60-80mm stone, for example, it means that the stones pass through a 80x80mm square mesh. and they do not pass through a 60x60mm one.
A 100mm stone can pass through that 80x80 mesh. long and 65mm. wide so there may be a percentage of stones greater than 80 and less than 60mm.

stone breaking

On the other hand, in stones larger than 60mm. There is a percentage of up to 10% of stones that can break during classification, washing, loading and unloading. Today we do not have machinery that prevents these breakages.

In the photos you can see, you only see real products, no broken parts 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 transportation. This is not a problem when using it; The stone will wash itself over time or you can pour water on it before using it.
