Effect of Temperature on the Thickening Time Property of Cement Slurry

Abstract

This study was carried out using API recommended practice 13B-2 in a cement laboratory, and the essence was to establish the effect of an increase in temperature on the thickening time of cement slurry the test was carried out at different temperatures of 80 o F, 100 o F, 120 o F, 140 o F and 160 o F and retarder concentrations of 0.03gal/sk, 0.07 gal/sk, and 0.10 gal/sk. The test results obtained at various concentrations and corresponding temperatures showed that there is a decrease in thickening time at 100BC as the temperature increases, at concentrations of 0.03 gal/sk, 0.07gal/sk, and 0.1gal/sk and temperature of 80 o F the thickening time were 428minutes, 561minutes, and 723minutes, while at a temperature of 160 o F the thickening time were 173minutes, 233minutes, and 297minutes.This, therefore, shows that temperature is a major factor in the slurry design and it has a significant effect on the thickening time of cement slurry.
