发酵法黄腐酸磺化产物减水性能的研究

Study on the Water-reducing Property of Sulfonated Fermenting Fulvic Acid

以腐植酸 (HA)类新技术产品 -发酵法黄腐酸 (BFA)的磺化 (磺甲基化 )产物为研究对象 ,就其物化特性和泡沫性能以及表面活性、水泥净浆流动度和减水率等一系列减水性能进行了较系统的考察和研究 ,并与常用减水剂木钙 (木质磺酸钙 )对比 ,提出发酵法黄腐酸应用于混凝土减水剂的可能性。文中还对BFA磺化 (磺甲基化 )产物的减水机理进行了探讨。

The physical\|chemistry properties, foam stability, surface activity, cement slurry fluid property and water\|reducing property of the sulfonation products of the fermenting fulvic acid was investigated and compared with calcium lignosulfonate. A application of fermenting fulvic acid in concrete water\|reducing was exploved. The water\|reducing mechanism of the sulfonation products of the fermenting fulvic acid was discussed.\;
