Unlike ordinary concrete, CLSM has much lower strength. The strength of CLSM is less than , while ordinary concrete has strengths exceeding . As a result, CLSM is not suitable for supporting buildings, bridges, or other structures. Instead, it is primarily used as a replacement for compacted backfill.〔Howard, Amster K., and Jennifer L. Hitch, eds. ''The Design and Application of Controlled Low-strength Materials (flowable Fill)''. West Conshohocken, PA: ASTM, 1998. 3. Print.〕 It also flows much better than ordinary concrete, having the consistency of a milkshake. The first known use of CLSM was in 1964.〔(【引用サイトリンク】work=Portland Cement Association )〕 CLSM is typically a ready mix concrete rather than soil cement which is a low strength cement made using local soil, and is similar to a slurry. 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「Controlled low strength material」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.
