1 一种可溶性发气剂调控微观孔结构的CA砂浆 CN200910157304.8 2009-07-24 CN101962279A 2011-02-02 王万金; 贺奎; 郑丽丽; 夏义兵; 李海峰; 查炎鹏
发明涉及一种高速路、城市高速轻轨用的可溶性发气剂调控微观孔结构的CA砂浆。一种可溶性发气剂调控微观孔结构的CA砂浆,其特征在于它包括泥、乳化沥青、砂、膨胀剂、可溶性发气剂、减水剂缓凝剂和水。各原料所占重量份为:水泥:100份,乳化沥青:30-50份,砂:80-120份,膨胀剂:1-15份,可溶性发气剂:0.01-1份,减水剂1.5-2.5份,缓凝剂0.03-0.06份,水18-25份。由于该方法提供的可溶性发气剂可以溶解于水中,实现以分子水平分散,产生的气泡孔径、数量可控,分布均匀,可有控制浆体塑性收缩,并避免形成大孔和连通孔,提高含气量的有效性,因而可以有效地改善CA砂浆的微观孔结构,提高CA砂浆的饱满度、抗冻性能和抗疲劳性能。

8 Admixture for cement JP13849499 1999-05-19 JP2000327382A 2000-11-28 HANADA MINAMI; AOKI KAZUSHI; NISHIYAMA NAOHIRO; KOBAYASHI TOSHIMITSU; MIHASHI HIROZO
PROBLEM TO BE SOLVED: To obtain an admixture that can maintain the fluidity for a long time, reduces the transportation trouble with reduced slump loss in the pumping and facilitates the cement casting into the framework by pulverizing an organic compound that is insoluble or slightly soluble in water in a specific temperature range and melts at a specific temperature in a specific average particle size and admixing a retardant to the powder. SOLUTION: The organic compound to be employed is insoluble or slightly soluble in water at 4-20 deg.C, melts at 30-100 deg.C and the average particle size is adjusted to 10-500 microns. In an embodiment, this organic compound is selected from the group consisting of wax, fat and oil, fatty acid, fatty acid ester, metallic soap, higher alcohol and thermoplastic resin. In a preferred embodiment, the retardant is selected from fluoride, phosphate, borate, hydroxycarboxylic acid (or its salt), ketocarboxylic acid (or its salt), saccharide or sugar alcohol. According to the slump flow test (JIS A 1101), the value is 18.0 cm, in the case of no addition of the retardant, while 13.0-14.0 cm in the case of 0.5 wt.% based on the cement.
