Design and Early Age Performance of Sustainable One-Part Geopolymers for Well Cementing

Summary One-part geopolymers, known as “just add water” (JAW), alkali-activated formulation is presented in this work. This work reveals the design and development of short-term properties JAW geopolymers for use oilwell cementing well abandonment. Granite-based mix designs normalized with a byproduct slag small amount microsilica precursors were developed. The solid activator composed potassium silicate hydroxide, which are mixed to synthesize formulation. Zinc oxide used strength booster admixture. developed granite-based characterized by investigating reaction phases mechanical properties. Dissolution, heat evolution, pumpability, development, mineralogy also studied. results show that positive correlation among all given analyses final geopolymeric product quite observable. favorable be added optimizing precursor enhance solubility leads much higher evolutions. Furthermore, it develops early up 16 MPa without any negative effect on investigated one-part geopolymer slurries.
