しゃぶこんは、学術的用語ではないので訂正をしたほうがよろしいのでは。さらに、この表現ですと、スランプが大きいコンクリートが『しゃぶこん』という意味にとられてしまいます。では、高流動コンクリートは、すべて『しゃぶこん』なのですか？--以上の署名のないコメントは、124.209.245.101（会話/Whois）さんが 2007年11月17日 (土) 23:19 (UTC) に投稿したものです。[返信]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2007-11-17T23:19:00.000Z","author":"124.209.245.101","type":"comment","level":1,"id":"c-124.209.245.101-2007-11-17T23:19:00.000Z-\u300c\u3057\u3083\u3076\u3053\u3093\u300d\u306b\u3064\u3044\u3066","replies":[]}}-->
