Abstract
A method for manufacturing porous shaped articles, such as flat or channel shaped insulation plates, blocks and similar building elements, in particular for building completely insulated houses, the articles obtained by this method and building constructions erected from these articles, in which method spheres of expanded porous resinous foamed material are blended with a binder, comprising a mixture of a bituminous product, and waterglass with a waterglass content of at the most 75% by weight, while at the end of this blending operation a quantity of particulate or powdery material including an additive such as sand is added to and co-blended with said blend until the mass again consists mainly of loose spheres, whereupon cement is added to the blend and the entire mixture is subjected again to a second mixing operation, while metering a quantity of water, and the mixture thus finally obtained is formed into the desired articles by compression and vibration followed by drying said articles in a self-supporting condition.
