改性木质素磺酸钙制备高效减水剂的应用研究
Study on the Application of superplasticizer Made from modified Calcium Lignosulphonate
【摘要】 利用化学处理方法 ,对木钙进行改性 ,并与萘系高效减水剂复合配制成改性木钙复合外加剂 ,该外加剂具有高减水性 ,高早强性 ,低缓凝性 ,可大大降低萘系高效减水剂成本 ,拓宽了木钙的应用范围。
【Abstract】 Modified Calcium Lignosulphonate compound admixture is made up of modified Calcium Lignosulphonate through chemical treatment and Naphthalene Sulphonate superplasticizer.This admixture has high water reducing,low set retarding,high early strength and can reduce the cost of the Naphthalene sulphonate admixture and widen the applied range of calcium lignosulphonate. 〔
