Effects of Civil Construction Waste on Properties of Lining Mortars

Brazilian civil construction generates a huge amount of waste in different stages of construction, mainly due to the work methodology used in construction sites. The objective of this work is to study the inclusion of the residual of the civil construction in the sand mass in 0, 10 and 20%, with mortars used to cover masonry. For this study, the beneficiation of the material in crusher was obtained so that it obtained granulometry similar to sand and the most recurrent technological tests in mortars for this purpose, as the mechanical resistance (compression and flexion), water absorption and determination of the coefficient of Capillarity beyond the index of consistency, according to Brazilian norms, that define parameters of execution the technological tests. The results showed that the mortars after the incorporation presented value within the norm except the consistency and capillarity to the 20% that presented problems of fluidity and durability, hindering its use.
