摘要:
[Object] To provide a building material having excellent durability. [Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.
摘要:
Die Erfindung betrifft ein statisch unwirksames Formteil zur Befestigung an einer Gebäudewand oder -decke, wobei das Formteil zumindest einen mineralischen Leichtfüllstoff und ein Bindemittel enthält. Erfindungsgemäß umfasst der mineralische Leichtfüllstoff geblähte Partikel mit einer geschlossenzelligen Struktur und/oder einer geschlossenen, vorzugsweise glas- oder sinterartigen Oberfläche. Des Weiteren betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Formteils unter Verwendung eines mineralischen Leichtfüllstoffs sowie die Verwendung geblähter Partikel wenigstens eines glasreichen vulkanischen Gesteins als mineralischer Leichtfüllstoff.
摘要:
Methods and compositions are provided that relate to weighted elastomers. The weighted elastomers may comprise an elastomer and a weighting agent attached to an outer surface of the elastomer. An embodiment includes a method of cementing that comprises providing a cement composition containing cement, water, and a weighted elastomer. In addition, the cement composition may be introduced into a subterranean formation and allowed to set therein.
摘要:
A composition based on foamed perlite and magnesia cement for forming constructional thermo insulating elements and a method of making thereof. The composition comprises additionally surface active substances such as methylcellulose, bentonite as swelling agent and H 3 PO 4 , NaH 2 PO 4 .2H 2 O and NH 4 H 2 PO 4 . The made constructional articles have an even finely porous structure and can be easily machined or processed; they resist against passive flame and biologic agents, have antibacteric properties, are free of bad odours and do not emit environmental noxious substances.
