摘要： PROBLEM TO BE SOLVED: To provide a centrifugal forming aid comprising a high-performance water reducer composition used for mortar and concrete used for civil engineering constructions, buildings, structures, and concrete products, which increases a water-reducing ratio, decreases a slump loss with time, improves dehydrating and compaction, and gives high-strength concrete and high-strength centrifugally formed products having a good workability, and to provide a cement composition using it.
SOLUTION: The centrifugal forming aid comprises a high-performance water reducer composition comprising a high-performance water reducer and an alkali metal sulfate, where 2-100 pts.wt. of the alkali metal sulfate is mixed with 100 pts.wt. of the solid part of the high-performance water reducer. The cement composition is formed by containing cement and the centrifugal forming aid, where 0.6-4.0 pts.wt. of the centrifugal forming aid on the basis of the high-performance water reducer is added to 100 pts.wt. of cement.
