Hydrous silicate mineral Vermiculite lightweight aggregate in concrete
What are Vermiculite ?
Vermiculite are a hydrous silicate mineral which is classified under phyllosilicate. The expansion of the mineral on heating is termed as exfoliated vermiculite. It is formed by weathering or hydrothermal alteration of Biotite or phlogopite.
Character: Non-toxic, flavorless, lightweight, corrosion resisting, netural PH 6.5-7.5 etc.
Size: 20-40mesh, 40-60mesh, 1-3mm, 2-4mm, 3-6mm, 4-8mm etc.

Vermiculite is a mineral similar to mica. During a process called Exfoliation, Vermiculite is subjected to intense heat and can expand up to twenty times its original size. As Exfoliation occurs, millions of microscopic gaps are created within the plates which give Vermiculite excellent insulation and water retention properties. Besides these highly beneficial qualities, Vermiculite is lightweight, air entraining and absorbent. It is also environmentally friendly, chemically neutral and virtually sterile after exfoliation
Vermiculite concretes are lightweight, have good insulating properties and are intrinsically fire resistant. Vermiculite concretes may be used for insitu roof and floor screeds and in the fabrication of pre-cast products. Vermiculite concretes can also be used for insulating around back boilers and as a fire back support material.
