Avaliação de desempenho estrutural de protótipo com paredes construídas com blocos EVA

Abstract: Resumo A utilização de resíduos de EVA (Etileno Acetato de Vinila), resultado da produção de sandálias, na construção civil tem sido objetivo de pesquisas nos últimos 10 anos. Sabe-se que tais resíduos têm grande potencial para serem empregados como agregados leves, em substituição aos agregados naturais, na elaboração de compósitos cimentícios alternativos. Este artigo, além do destaque para a evolução dos estudos de aplicação desses compósitos na produção de blocos leves, apresenta uma importante etapa do pr… Show more

“…For calculation of the compression resistance and for conversion of the measurement into MPa units, the following equation was used (Eq. 1): (1) where fck is the resistance to compression (MPa), F is the force (tf), and A is the area of the top of the test specimen (the average value of 78.54 cm 2 was used).…”

“…Industrial development in many regions of Brazil, together with demographic expansion, have increased the production of various types of solid wastes, including industrial residues [1,2]. The lack of control in treating such wastes has led to serious environmental consequences associated with many types of pollution, as well as exhaustion of landfill sites.…”

“…Usou a relação de água material cimentício de 0,7; 0,8 e 0,9 quando incorporou EVA e 0,8; 0,9 e 1,0 ao usar a vermiculita. Com o propósito do desenvolvimento de elementos de revestimento para proteção térmica de alvenarias, comprovou que, o aumento da relação água/gesso diminuiu a consistência e ampliou os tempos de início e fim de pega do compósito, enquanto que, o aumento do teor de adição de EVA diminuiu o tempo de início e fim de pega e aumentou a consistência desse [5]; [7]; [8] Macedo avaliou forro de gesso modificado com EVA, verificando um incremento como material para isolamento térmico (redução de até 1,8 ºC), quando comparado ao forro de gesso comum.…”

“…Part of this material, after passing through autoclaves returns to the production process in the form of raw material, however the non-usable leftovers serves as fuel in industrial ovens [4]. When burning rubber, enormous amounts of particulate material and toxic gases are generated, damaging the environment [3]. [5] the SBR based waste was characterized, from the footwear industry of Campina Grande, reaching the conclusion that this waste belongs to CLASS I -DANGEROUS, but said that, being coated by cementitious matrix, this characteristic is eased.…”
