DEF represents one of the types of Internal Sulfate Attacks (ISA) related to an expansive chemical reaction that occurs inside of concrete involving the sulfates from cement. Experiments involved the assessment of expansions, compressive and tensile strengths as well as microstructural characteristics over time. It was observed that tests performed on mortars and with a specific mix required an extended evaluation period to distinguish the behaviors. Furthermore, high early-strength cement featured the worst binder when faced with DEF.</p&gt;}, number={3}, journal={Revista ALCONPAT}, author={Tiecher, Friancieli and Langoski, Marinês and Hasparyk, Nicole}, year={2021}, month={Sep.}, pages={1 - 16} }
