Fire resistant foamed material for coatings, insulation or mouldings - made by adding hydrogen peroxide to mixt. of magnesium chloride and magnesia

Material is based on Mg oxychloride or Mg oxychloride-cement, starting from an aq. suspension of the MgO and/or Mg(OH)2 with MgCl2; the suspension also contains fibres esp. chopped glass fibres, and a surfactant. The suspension is converted into foam by adding a foam ant, viz. H2O2 and/or other peroxide evolving O2, plus an activator, esp. an Mn (II) cpd., and also a pore promoter, viz, a water-soluble or -dispersible cellulose-deriv., -ether, or -ester, and/or a dispersion of synthetic resin. The glass fibres are pref. chopped glass mats or fabric with fibre length 2-7, esp. 3-5 mm. The material is used esp. as a coating 0.3-12, esp. 1-4 cm thick on metal, wood, concrete, brickwork, building elements, plastics. Use of Mg powder as a foamant is avoided because the Mg constitutes a fire hazard both in the mfr. and use of this type of material.

PROCESS FOR MAKING FIBRE REINFORCED CELLULAR CEMENTIOUS BUILDING MATERIALS

A process for making fibre reinforced cellular cementious building materials. Firstly, mix separately a foam slurry and a cementious mixture containing water and random glass fibres.

Concrete element and a method for producing this element and a building construction containing this element

In concrete elements such as facade, wall and floor slab panels, the concrete front panel and rear panel alone are mutually fastened by an intermediate thermal insulating layer of mineral fibre aggregate. The concrete and insulating fibre aggregate are worked into one another in the boundary layer such that the concrete (cement paste) being worked into the insulating fibre aggregate achieves a suplementary high fibre concentration. This combined with using insulating fibre aggregate being laminated and having a high density has the effect that the forces from the front panel can be transferred to the rear panel such that by this method a stressedskin construction is created. Front and rear panels are made as fibre-reinforced concrete (cement mortar) in thicknesses of the dimensions approx. 1-3 cm and with fibres of polypropylene or a corresponding chemical, and possibly also with mineral fibres. The construction is thus totally without steel such as reinforcements or anchors between the concrete panels like in the prior art panels of the conventional concrete elements.
