SummaryThis dissertation presents the development of a cementitious composite reinforced with PBO fabric, designed to maintain good mechanical performance at moderate temperatures. To this end, a calcium aluminate cement (CAC)-based matrix was formulated and its characteristics evaluated through calorimetric tests, aiming to understand the thermal behavior and hydration kinetics. Consistency and compression tests were performed at different ages (8, 10, 24, and 48 hours, as well as 7 and 28 days) at room temperature.
Additionally, residual mechanical tests were conducted after exposure to 200°C, 300°C, and 400°C, applied 48 hours after molding, with subsequent cooling to room temperature. During this stage, both the compressive strength and tensile behavior of composite plates molded specifically for this purpose were evaluated. The results allow us to evaluate the effectiveness of the matrix and textile reinforcement under adverse thermal conditions, providing insights for applications in structural repairs and environments. offshore accounts.
