SULFATE RESISTANCE MECHANISM OF HIGH- PERFORMANCE CONCRETE CONTAINING NCIMA Baoguo Wuhan University of Technology摘 要:<正> It is found that the incorporation of Nitrite Corrosion Inhibitor (NCI) greatly weakens the resistance of mixtures to sulfate attack. To study the mechanism of this phenomenon, in this paper, the influence of NCI additionon......
:博士点基金资助课题! ( 96 0 5330 9); Reaction behavior between calcium oxide or calcium hydroxide and aluminate solution with heavy caustic soda Abstract: The reaction between calcium oxide or calcium hydroxide and aluminate solution with heavy caustic soda was studied. The reaction activity of CaO was better than that of Ca (OH) 2 under the same condition, which......
