Abstract Scope |
Civil construction is a sector of extreme impact in the generation of waste, and construction waste (CW) is a large part of the total mass of urban solid waste in a medium and large city. In the present research, concrete traces were produced using Construction waste (CW) in partial and total replacement of fine aggregates in order to reduce, recycle and reuse this large amount of waste. The concrete was produced with CPII cement, with a volume ratio of 3:2:1 (sand, zero gravel and cement). Different traces were produced with construction waste instead of sand, in the proportions of 0%, 25%, 50%, 75% and 100% (0R, 25R, 50R, 75R and 100R). The results obtained indicate good quality of the different concrete mixes with the use of construction residues, verifying quality service and good resistance, according to statistical criteria (ANOVA and Weibull). |
