- W991999191 abstract "N-2000 is an admixture for concrete, with a low slump loss, high range water-reducing ratio and long-time retarding. The N-2000 is made up of naphthalene-sulfonic-maldehyde polycondensation (NSMP) and ATMP. Its characteristic results from the synergistic effects of NSMP and ATMP. The results show that when O.7%-1.2% of N-2000 is added to con crete (by mass of cement), the water reducing ratio is up to 20%-30%, and the slump of fresh concrete can be retained for 2 hours without significant loss. N-2000 can not only improve the workability of fresh concrete but also increase the strength of the hardened concrete, especially early strength. It is also proved to have a good compatibility with various cements." @default.
