Effect of a carboxylic acid/sulfonic acid copolymer on the material properties of cementitious materials [J].

SANS is extensively applied for static and dynamic-structural analyses in materials science and biology fields such as in metallurgies, ceramics, polymers, colloids, vesicles, viruses, etc. [4] because of its powerful and non-destructive technique to investigate a structural properties [5] and inhomogeneity patterns in materials for scale range of 1-100 nm [6].
EXPERIMENTAL Zinc acetate (Zn (CH3COO) 2. 2H2O), ethanol, and diethanolamine (DEA) were used as starting materials. 0.5 M Zn2+ solution was prepared by dissolving zinc acetate in 35 ml of ethanol.
