Probably the first ever abrasion resistant insulation material.   It is an aluminosilicate material containing hollow ceramic balls called cenospheres.  The matrix is extremely fine, cohesive and dense, but the bulk of the volume is sealed air bubbles.

The density is 1,7kg/litre

The cold crushing strength climbs to around 50 MPa at 400°C and drops back to 25 to 30 MPa at 1250°C.

Installation; Can be poured with an addition of +16% water, and will flow self-levelling.

Can be plastered with plus 12% water.

A variant is Archiecoat which can be plastered with +16% water and painted about 3mm thick with an addition of  +20% water.

Applications;  Protection of steel exposed to heat;  Ducting and shells of dust collectors etc.  Can be trowelled onto expanded metal.
