“滞后泌水”导致承台砂线缺陷的技术分析与试验研究

Technical Analysis and Experimental Research of Bare-sand Defect of Pile Caps Leaded by Lagging Bleeding

在承台海工混凝土中掺入新型复合氨基醇阻锈剂后出现"滞后泌水"现象,导致砂线的外观缺陷,就此进行了试验研究与成因分析表明,含气量过大是造成"滞后泌水"的根本原因。

Lagging bleeding phenomenon is appeared after adding corrosion inhibitor maded by composite amino alcohols into marine concrete of pile caps,which leads to bare-sand defect on concrete.It is considered that oversize air content is the basic reason for lagging bleeding.
