我们选用水泥为52.5R àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
UNF-1高效减水剂，掺量：1%àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
UEA膨胀剂 掺量：12%àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
水灰比不大于0.35àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
可以0.35的水灰比的话稠度很大，达不到14-18S之间;àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
要达到只能水灰比达到0.42的时候。àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
求助各位！怎么才能满足稠度要求，外加剂，膨胀剂都是厂家推荐掺量àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë

适当提高减水剂的掺量 。厂家推荐的掺量为一般掺量，你可以进行掺量与碱水率的曲线试验，确定减水剂的掺量。àã1 ¾F)Jð_bbs.3c3t.com;Y,ÒÖÀë
