Confecção e análise de argamassa para reboco com utilização de sacos de cimento

Abstract

There are many impacts generated by civil construction on the environment and any incentive in research that seeks to minimize these impacts is important. Faced with this problem, the idea of sustainability was introduced in civil construction aiming at viable alternatives to reduce such impacts, and one of the ideas is to propose the addition of waste in the manufacture of materials, making studies of efficiency and economic viability necessary. This work’s purpose is to use cement bags, which would be discarded as civil construction waste (CCW) in plastering, replacing part of the fine aggregate (sand) and the performance’s experimental analysis of these mortars was made in the Centro Universitario do Rio Grande do Norte’s (UNI-RN). It was evaluated the absorption beginning by NBR 9778, ABNT (2005), then the curing time was analyzed with the NBR's 6118, ABNT (2014), assistance, lastly the compressive strength was used the NBR (5739), ABNT (2007), which the outcome by the average of broken samples was 23.03 MPa, the average absorption was 2,178% and the economic savings for each sand cubic meter used was 10%. Concluding positively the result.
