High tensile construction material - uses a matrix mixt. of mineral bonding with organic synthetic fibres and fibre dust with embedded glass fibre netting

摘要

The high tensile compound material, which can withstand dynamic forces, has a matrix of mineral bonding and fibres of organic synthetic staple fibres with organic synthetic fibre dust. Netting is embedded into the matrix material mixture in layers. The organic synthetic fibres are pref. used at a rate of 2-5% of the bonding material mass, and the organic synthetic fibre dust is added at a rate of 5-10% of the bonding mass. The fibres have a length of 2-15mm and the fibre dust length is 0.05-2mm, and pref. 0.1-1.5mm. The fibres are pref. of polypropylene. The netting layers are of woven glass fibres, with a mesh width of 3-20mm in a material weight of 200-700 g/m2, for insertion into the matrix of bonding material and fibres. USE/ADVANTAGE - The material, especially based on plaster or cement, is used as plates or shaped bodies for new construction or restoration of dwellings, commercial property and industrial sites. The material, on bending forces, has a monolithic fracture behaviour, with the external forces transferred to the inner netting for strengt
