Effect of addition sodium lignosulfonate additive in g class cement on thickening time and compressive strength

Abstract

Cementing process was not good can be caused by the poor planning of cement slurry carried out in the laboratory. Poor cementing certainly cannot meet the expectations and goals of the cementing process. The purpose of this study was to select the right and optimal cement composition by testing sodium lignosulfonate retarder additives for thickening time and compressive strength. The methodology used in this study was laboratory testing using class G cement. The addition of sodium lignosulfonate additive in this class G cement was obtained the highest thickening time value at a concentration of 1.5% temperature 150 ° F for 24 hours test result.
