Abstract
A method including providing a geopolymer recipe comprising a geopolymer material, and a required compressive strength, using a compressive strength model of the geopolymer recipe to predict a compressive strength and comparing the required compressive strength to the predicted compressive strength output of the compressive strength model, preparing a geopolymer composition based at least in part on the compressive strength model, and introducing the geopolymer composition into a subterranean formation. The geopolymer material can contain an aluminosilicate source, a metal silicate source, an alkaline activator, and water.
