China Vermiculite Used in in-Ground Swimming Pools to Provide a Smooth Pool Base

Vermiculite
The Name
vermiculite,expanded vermiculite,Exfoliated vermiculite
The name vermiculite comes from the Latin "vermiculus," meaning larva or small and worm-like, or "vermiculare," meaning to breed worms, for its characteristic look when undergoing exfoliation.
What is vermiculite?
Vermiculite is the name of a group of hydrated laminar minerals (aluminum-iron magnesium silicates) which look like mica.
Vermiculite deposits are associated with volcanic ultramafic rocks rich in magnesium silicate minerals, and flakes of the mineral range in color from black to shades of brown and yellow. The crystal structure of vermiculite contains water molecules, a property that is critical to its processing for common uses.
Concrete:
As a lightweight aggregate for plaster, proprietary concrete compounds, firestop mortar and cementitious spray fireproofing: Exfoliated vermiculite is used in both hand and spray applied general building plasters to improve coverage, ease of handling, adhesion to a wide variety of substrates, fire resistance, and resistance to chipping/cracking/shrinkage.

Used in in-ground swimming pools to provide a smooth pool base: Finer grades of exfoliated vermiculite plus Portland cement may be combined either on site or a factory premix to provide a base for swimming pool vinyl liners. These mixes are either pumped into place using a rotor stator pump or hand poured.

Silicate and Alumina Bonded Bricks-Shapes

Vermiculite can be used in conjunction with silicate or alumina which is then pressed to form various basic bricks and also more intricate shapes depending on your application. These silicate or alumina bonded bricks-shapes are used extensively as an insulator for various high temperature industrial applications (yet with out exceeding average temperatures of 1100 in particular relating to the refractory industry. Silicate or Alumina Bonded bricks-shapes made with Vermiculite act as an economical advantage over previous methods of insulation, its insulating characteristics are also comparative to previous insulation methods.

Using a process called exfoliation - in which vermiculite flakes are heated to 900 degrees Celsius or higher, causing water within the flakes to flash to steam and expand - crude vermiculite ore is processed into particles that are eight to 20 times larger. The resulting lightweight material is chemically inert and fire resistant, with low density and low thermal conductivity. It is also odorless, has high liquid absorption capacity and catalytic properties.
