【Abstract】 The compatibility of common additive and flying ash is studied. The additive contains three kinds of naphthalene additive, Jianzhubao-3, FDN-500 and MD-150, and one kind of poly carboxylic acid additive(KFDN-2000A). The flying ash contains class Ⅱ ash and class Ⅲ ash. The research suggests that naphthalene additive and poly carboxylic acid additive have better compatibility with flying ash. They all demostrate better dispersive result to the cement mortar with flying ash.更多还原
