Abstract    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.

چکیده   

مواد شیمیایی مختلف می توانند تاثیر متفاوتی روی خواص دوغاب سیمان داشته باشند. در این مقاله تاثیرات متفاوت ال-اسکوربیک اسید بر روی خواص مهم دوغاب سیمان ساخته شده از سیمان چاه نفت کلاس G بررسی شده است. این خواص شامل میزان سیال آزاد، خواص رئولوژیکی، زمان نیم بندش و استحکام تراکمی بود. چندین دوغاب سیمان با مقادیر متفاوت از ال-اسکوربیک اسید ساخته شد. با افزایش ال-اسکوربیک اسید میزان سیال آزاد کاهش یافته و خواص رئولوژیکی دوغاب ها بهبود یافت. این بهبود در میزان سیال آزاد و خواص رئولوژیکی با افزایش ال-اسکوربیک اسید ادامه یافت. با افزایش میزان ال-اسکوربیک اسید تا مقدار 03/0 درصد وزنی سیمان، زمان نیم بندش کاهش و استحکام تراکمی افزایش یافت. به عبارت دیگر ال-اسکوربیک اسید تا 03/0 درصد وزنی سیمان بعنوان شتاب دهنده و در مقادیر بیشتر بعنوان کندکننده زمان نیم بندش عمل کرد.
