| Abstract: | Four water reducing agents,mainly composed of lignin sulphonate,were obtained from four types of pulping waste liquor derived by different materials of different pulp making methods.At the same time,the properties of water reducing were rudimentarily discussed.The results show that adding prepared water reducing agents can be used to reduce water and improve the strength of cement bonded sand mortar. |
