COMPOSITION FORMANT EN MELANGE AVEC DE L'EAU UNE PÂTE POUR LA REALISATION D'UN REVETEMENT DECORATIF SUR UN SUPPORT ET OUTILS UTILISES A CETTE FIN L'invention se rapporte à un concept de décoration de support, en particulier de surfaces intérieures de bâtiment, concept dans lequel on utilise une composition sèche destinée à être mélangée avec de l'eau pour préparer plus facilement une pâte applicable sur le support, en vue de réaliser un revêtement décoratif ayant un "toucher béton", un "aspect béton", une "dureté béton", et qui de surcroît est décollable à la décolleuse à papier peint. L'invention concerne un procédé d'obtention d'un revêtement décoratif béton par mélangeant avec de l'eau une composition pulvérulente sèche comprenant en pourcentages massiques sur sec : de 30 à 60 de ciment, de 30 à 60 de charge, de 0,5 à 10 d'au moins un agent absorbant, de 0,01 à 1 d'au moins un agent fibreux de flexibilité, de 0,01 à 3 d'au moins un retardateur de prise, de 0,01 à 1 d'agent mouillant, de 0,1 à 20 de particules décoratives, de 0,5 à 10 d'au moins un durcisseur, et de 0 à 1 d'au moins un colorant. Cette procédé est mise en oeuvre par des outils comme une taloche crantée pour l'application de la pâte, un peigne éventail pour réaliser un effet griffé, une brosse à poils de nylon pour réaliser un effet brossé ou peigné, une spatule biplaque à structures pour réaliser un effet rayures ou stries.

A concrete mix design having a slump class from SI to S5 or a flow class from Fl to F6 and a workability retention between 10 minutes and 120 minutes, comprising from 150 to 600 kg of cement per cubic meter of concrete, aggregates selected from the group consisting of sand, fine aggregates, coarse aggregates or combinations thereof containing between 0.5 wt.% and 75 wt.% of phyllosilicates, is characterized in that the concrete mix design includes an admixture system 1 which is based on 100% polycarboxylate ether based copolymer (PCE), the admixture system 1 comprising at least one component B1 being a PCE copolymer.
摘要:
The invention relates to a framework material for biologically recyclable reactive filters, with a content of fibres; a content of biologically compatible porous stabilising additive, and a content of biologically compatible inorganic binder, wherein the combination enables colonisation by microorganisms and/or incorporation of modifying materials, such as adsorbents, nutrients, pH value modifiers and/or catalytic materials and/or hydrophobisation and is structurally stable in a moist environment. The invention also relates to a method for producing said framework material.

A refractory strucutral element is provided that is useful for lining the inner surface of a construct typically used as a kiln or other high temperature system. An element includes a stem portion associated with a flared end block portion whereby the flared end block portion is compatible with other strucutral elements to form a substantially continuous tiled surface when a plurality of refractory structural elements are laid adjacent to each other. The stem portion optionally has a plurality of protrusions decorated on its outer surface that may serve to adjust heat dissipation from the element.

Ways of applying microwaves to feedstock to be processed are disclosed. One embodiment relates to heating inter-layer water in vermiculite to expand the vermiculite. Another embodiment relates to heating water in oil-contaminated materials and waste products, such as drilling cuttings, contaminated soils and certain types of animal by-products, to drive out oil. In some embodiments a microwave tunnel applicator has the microwaves applied from beneath the feedstock.
