The thickening properties, rheological properties, density and flexibility of cement paste of sodium lignosulfonate, Ethanolamine, Diethanolamine and Triethanolamine were evaluated. The results show that ethylene glycol, Ethylenediamine and Sodium ethoxide can change the properties of cement slurry to a certain extent, but will not significantly improve the mechanical properties of cement slurry. Diethanolamine and Triethanolamine can reduce the thickening time of cement slurry to 57 min and 22 min respectively when they have little effect on the initial consistency and rheological properties of cement slurry.

摘要

The thickening properties, rheological properties, density and flexibility of cement paste of sodium lignosulfonate, Ethanolamine, Diethanolamine and Triethanolamine were evaluated. The results show that ethylene glycol, Ethylenediamine and Sodium ethoxide can change the properties of cement slurry to a certain extent, but will not significantly improve the mechanical properties of cement slurry. Diethanolamine and Triethanolamine can reduce the thickening time of cement slurry to 57 min and 22 min respectively when they have little effect on the initial consistency and rheological properties of cement slurry.
