Mechanical Behavior of Fly Ash based Geopolymer Cement as Well Cement

With the increasing awareness of global warming, geopolymer cement has been identified as one of the methods in reducing the emission of CO2 during oil well cementing operation. However, it is important that geopolymer cement can meet the specific requirement of oil well condition in order to be the substitute of current conventional cement system. The use of geopolymer in cement system is a new technology that yet needs proper study to yield better advantages of it.
In this research, the main objective was to study the effect of temperature to the mechanical properties of the flyash based geopolymer cement. In the early stage, literature review on previous research showed utilizing geopolymer in cement composition will significantly reduce C02 emission and enhanced properties characteristic as well. Detailed study on geopolymer compositions, conventional cement, and additives was carried out. In the experimental part, the geopolymer cement were tested in well condition and changes in the mechanical properties are recorded and analyzed.
As the conclusion, from the obtained results geopolymer cement showed a degradation of mechanical properties after cured in the controlled well condition.
