AI Technical Summary
Technical Problem
Pozzolans vary in reactivity, leading to inconsistent cement slurry properties and limiting their use in certain geographic locations, especially at lower temperatures, as higher reactive pozzolans are required to achieve desired strength and temperature-dependent curing.
Method used
Contacting pozzolan materials with a catalyst during the supply chain to enhance reactivity, forming enhanced reactivity pozzolans through reactions that occur in storage or transport, maintaining material flow without additional handling steps.
Benefits of technology
Enhanced reactivity pozzolans exhibit improved compressive strength and rheological properties, allowing for wider cement slurry design flexibility and lower temperature curing, enhancing cement performance.

Abstract
A method of preparing an enhanced reactivity pozzolan may include: contacting a starting pozzolan with a catalyst material to form a mixture of the starting pozzolan and the catalyst material; reacting the mixture of starting pozzolan and catalyst material during an induction period to form reaction products; and recovering the enhanced reactivity pozzolan.
