Abstract:
The inherent light weight, toughness, low permeability, smooth surface finish and resistance to shrinkage cracking have all contributed to GFRC being an attractive alternative to traditional materials in the following areas of mining: 1) stabilization of rock tunnels by in situ spraying of thin skins; 2) construction of ventilation stopping walls both by a surface bonding technique and as a direct substitute for simple lime and sand mortars; 3) fire protection of timber packs by lightweight GFRC renders with improved adhesion and impact strength; 4) manufacture of drainage channels which are lighter in weight than their concrete counterparts and tougher than the asbestos cement alternatives; and 5) production of permanent formwork, which is lighter in weight and has a better surface finish than concrete and is much more efficient than the use of temporary shuttering.
