Abstract:
Port dredging is currently an important activity, as commercial demand has been growing exponentially. Thus, dredging is necessary to maintain adequate depth for navigation in port areas. Consequently, the amount of material dredged also increases, making it necessary to manage such waste. With the vision of circular economy and reuse, in addition to using less conventional materials in civil construction, the present work aims to produce a mortar where the lime binder will be partially replaced by Waste from dredging from Porto do Açu (RPA). Replacements are 10, 20 and 30% by mass in a standard mortar. Prismatic specimens (40 x 40 x 160 mm) were produced and kept at an average temperature of 25°C for 28 days. After the curing time, tests were carried out on flexural tensile strength, compressive strength, mass density and water absorption by capillarity. The results obtained were satisfactory, since the substituted mortar presented compressive strength and capillarity coefficient equivalent to the reference mortar, making its use possible..
