dc.description.abstractThe objective of this thesis is to generate a deeper understanding of how rapid setting and hardening cements perform when being exposed to environments that can hypothetically accelerate or reduce the alkali-silica reaction and delayed ettringite formation. It has been proved in preceding literature studies that ordinary portland cements expands to both coarse and fine aggregates depending on their level of known reactivity. In order to generate precise outcomes for the study of both Calcium Aluminate and Calcium Sulfoaluminate Cements’ reactivity, coarse and fine aggregates identified as non-reactive were utilized. Moreover, concrete exposure blocks were analyzed while exposed to field conditions, and concrete prisms and mortar bars were studied in controlled laboratory conditions. Specimens were studied based on standard and modified testing methods such as ASTM C1293, ASTM C1260, and the Kelham Method.
