Disclosed is a foam modifier, e.g., useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C6-C16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.

A thermally insulating cloth is provided. The thermally insulating cloth has a layered structure comprising at least three layers, a first and a second outer textile layer providing the outer surfaces of said cloth, and an intermediate layer, wherein said first and said second outer textile layer are laminated to the intermediate layer, said first outer textile layer having an air permeability of less than or equal to 40 cc/sec*5cm 2 , said second outer textile layer having air permeability of less than or equal to 40 cc/sec*5cm 2 , said intermediate layer comprising a textile fabric comprising aerogel powder, in an amount in a range of 1 to 70%w.
摘要:
A method of slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass bodies to define a bed, covering the bed with a layer of cementitious material to define a composite bed, and crushing at least a portion of the composite bed with an oncoming aircraft, wherein crushing the at least a portion of the composite bed removes kinetic energy from the oncoming aircraft to slow the oncoming aircraft. The composite bed is generally resistant to fire.

The present invention relates to a laminated tile, comprising a mutually connected solid tile body and concrete body. In the laminated tile, the concrete body has an open structure. The invention also relates to a method for manufacturing a 5laminated tile according to any of the preceding claims. The method comprises the steps of: - applying an adhesive to a first surface of said solid tile body, - applying a concrete mixture on top of said solid tile's first surface, said concrete having an open structure, and - hardening said concrete mixture and said 10adhesive for obtaining a laminated tile.
摘要:
Dry mortar mixture characterized by a glass mixture of expanded glass beads with a grain size d/D 0/8, mixed in a ratio of between 1:1 and 1:3, for example 1:2 with a dust poor or dust free binding mixture of hydraulic binders and stone granules in the weight ratio of 1:2 to 1:4. The glass has a discontinuous grain distribution. For the glass mixture the fractions 0.5/1.0 and 2.0/4.0 are present while the fractions 0.25/0.5 and 1.0/2.0 are absent. For the glass mixture preferably all grain sizes between 1.0 and 2.0 mm are absent and the grain size distribution is around an average, so that an open structure is obtained.
摘要:
The present invention provides a glass fiber board comprising a glass fiber and an inorganic binder, wherein the inorganic binder comprises an aluminum phosphate. The present invention provides a method for preparing the glass fiber board comprising (a) preparing an inorganic binder solution comprising an aluminum phosphate (b) applying the inorganic binder solution comprising the aluminum phosphate to a glass fiber; (c) compressing the glass fiber to which the inorganic binder solution comprising the aluminum phosphate is applied; and (d) drying the compressed glass fiber.
摘要:
Das Schäumungsmittel dient dem Schäumen eines Baustoff-Bindemittelleims oder einer Baustoffmaische zur Herstellung porenhaltiger Leichtbau- und Dämmmaterialien. Beim Aushärten der geschäumten Maische erzeugen die Schaumblasen Poren im Baustoff. Erfindungsgemäß wird zur Stabilisierung des aus dem Schäumungsmittel erhaltenen Schaums ein lang- oder mittelkettiger Polycarboxylatether (PCE) verwendet. Das Schäumungsmittel besteht aus einer schaumbildenden ionischen Tensid-Komponente, wenigstens einem Fettalkohol und wenigstens einem PCE in einem wässrig-organischen Lösemittel, das ausgewählt ist aus der Gruppe Alkylglykole, Alkylenglykole bis C6-Alkyl, Diglykole und Diglykolether, sowie optional bis maximal 20 Gew.-% bezogen auf die Mischung an weiteren Inhaltsstoffen. Weiterhin sind Verfahren zur Herstellung eines porenhaltigen Leichtbau- und Dämmmaterials mit Hilfe des Bindemittelleimschaums oder der geschäumten Baustoffmaische sowie zugehörige Porenleichtbauprodukte angegeben.
