چکیده
Various chemicals can have different effects on the properties of the cement slurry. In this paper, the different effects of L-ascorbic acid have been investigated on the important parameters of cement slurry made from class G oil well cement. These parameters included the amount of free fluid, rheological properties, Thickening Time, and compressive strength. Several cement slurries were made with different dosages of L-ascorbic acid. By increasing the amount of L-ascorbic acid, free fluids were decreased and rheological properties of the slurries were improved. This improvement in the amount of free fluid and rheological properties continued with an increase of L-ascorbic acid. Increasing the dosage of L-ascorbic acid to 0.03% by weight of cement, decreased the thickening time and increased the compressive strength. In other words, L-ascorbic acid acted as an accelerator up to 0.03% by weight of cement and would have the role of a retarder in higher value.کلیدواژه ها
