Geopolímeros submetidos a choque térmico

Geopolymers are alternative materials that have been gaining increasing attention due to their mechanical properties and environmental sustainability. However, their behavior under extreme temperature variations is still poorly explored. Therefore, the main objective of this work is to analyze how thermal shock affects the physical and mechanical properties of geopolymers. The research includes a detailed review of the existing scientific literature related to geopolymers, acid activation, and thermal shock phenomena, as well as controlled experiments for the manufacture of geopolymer samples followed by thermal shock cycles. As a result, it was observed that thermal shock leads to a loss of mechanical strength and changes in density and water absorption.
