翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Sulfur concrete ： ウィキペディア英語版 Sulfur concrete Sulfur concrete is a composite construction material, composed mainly of sulfur and aggregate (generally a coarse aggregate made of gravel or crushed rocks and a fine aggregate such as sand). Cement and water, important compounds in normal concrete, are not part of sulfur concrete. The concrete is heated above the melting point of sulfur ca. 140°C. After cooling the concrete reaches a high strength, not needing a prolonged curing like normal concrete. Sulfur concrete is resistant to some compounds like acids which attack normal concrete. Sulfur concrete was developed and promoted as building material to get rid of large amounts of stored sulfur produced by hydrodesulfurization of gas and oil. Sulfur concrete is also a possible building material for a lunar base. Up to 2011, sulfur concrete is only used in small quantities when fast curing or acid resistance is necessary. ==See also== *Asphalt concrete, similar aggregate material using 'bitumen' as a binder * Lunarcrete#Sulfur based "Waterless Concrete", for proposals for its use as a lunar construction material. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sulfur concrete」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
