No presente trabalho foram fabricados blocos de solo-cimento com adição de resíduos orgânicos, para avaliar o potencial de reutilização destes resíduos em blocos usados na construção de alvenarias de vedação. Os blocos foram confeccionados a partir de duas composições estudadas em trabalhos prévios, uma delas com a adição de resíduos orgânicos e outra sem resíduos, para objeto de comparação. Em virtude da heterogeneidade do resíduo orgânico adicionado aos blocos, foram realizados ensaios de medição de gases, em um ambiente controlado e submetido a presença dos blocos. Estes ensaios foram realizados com auxílio do analisador de gases Gasera One Pulse e apresentaram um contributo inicial para a análise da qualidade do ar interior em ambientes com a utilização destes blocos. Com os blocos de solo-cimento fabricados, foram construídos dois tipos de alvenarias: paredes de blocos com adição de resíduos, denominadas como provetes SCR, e paredes de blocos sem adição de resíduos, denominadas como provetes SC. Em ambos os tipos de parede utilizou-se mesma argamassa de assentamento, elaborada com os mesmos materiais dos blocos sem resíduos. Estas paredes foram submetidas ao ensaio de resistência à compressão, seguindo as recomendações apresentadas na norma EN 1052-1 [1]. As paredes SCR apresentaram uma resistência média à compressão de 3,13 MPa e as paredes SC apresentaram uma resistência média de 5,00 MPa. Apesar da menor resistência das paredes SCR, em relação as paredes SC, ao se comparar os resultados obtidos com os resultados encontrados por outros autores, para diferentes paredes de blocos de solo-cimento, concluiu-se que as alvenarias SCR apresentaram resultados acima da média. Além disso, o modo de ruptura das paredes SCR foi muito similar ao das paredes SC, quando submetidas ao excesso de carregamento, não sendo identificado nenhum comportamento anormal. Desta forma, concluiu-se que a adição do resíduo orgânico, aos blocos de solo-cimento, não é um empedimento para a aplicação destes na construção de alvenarias de vedação.
In the present work, soil-cement blocks were made with the addition of organic residues, to evaluate the reusing potential of these residues in blocks used for construction of non-load-bearing walls. The blocks were made using compositions that were studied in previous works. For comparison, two different compositions were manufactured, one with the addition of organic residues and other one without. Due to the heterogeneity of the organic waste added to the blocks, gas measurement tests were carried out in a controlled environment, on presence of the blocks. These tests were performed with the aid of the Gasera One Pulse, a gas analyser, and served as an initial contribution to the analysis of indoor air quality associated to the use of these blocks. With the manufactured soil-cement blocks, two types of masonry were built: masonry made with blocks with addition of waste, referred to as SCR specimens, and masonry made with blocks without addition residue, referred to as SC specimens. In both types of wall, the same mortar was used, made with the same materials as the blocks without residues. These walls were subjected to the compressive strength test, following the recommendations presented in EN 1052-1 [1]. SCR walls had an average compressive strength of 3.13 MPa and SC walls had an average strength of 5.00 MPa. Despite the lower resistance of SCR walls, compared to SC walls, when comparing the results obtained with the results found by other authors, for different masonry of soil-cement blocks, it was concluded that SCR masonry presented above average results. Furthermore, the rupture mode of SCR walls was very similar to rupture mode of SC walls and no abnormal behaviour was identified. Thus, it was concluded that the addition of organic waste to the soil-cement blocks would not be an obstacle to their application in the construction of non-load-bearing walls.
