Microstructure Behavior of Fly Ash-Based Geopolymer Cement

Acidizing is a widely used technique to stimulate an oil well in order to enhance its production. When portland cement is placed in contact with acid fluids, it will dissolve and, at some time, will be fully degraded because the acids have reacted with calcium silicate hydrate which resulted in the breaking up of the cement intergranular structure. This in turn will give …
