Protótipo. Paredes. Impactos. Cargas. Peça suspensa. The utilization of EVA (Ethylene Vinyl Acetate) waste, a byproduct from the production of sandals, in construction projects has been the object of research in the last 10 years. It is known that EVA waste has great potential to be used as lightweight aggregate, replacing natural aggregates in the production of alternative cement composites. As well as highlighting the development of research into the application of these composites in the production of light blocks, this study shows an important stage in the process of evaluation of the structural performance of the proposed precast. The evaluation of occupancy loads and impacts on the prototype walls built with EVA blocks was done through tests (impacts of soft and hard materials, repercussions of abrupt closing of doors and loads coming from suspended pieces) in order to simulate accidental and normal situations in building use. In the construction proce ss of the prototype, the EVA blocks proved to be easy to use in ways that are important to help reducing construction and demolition waste. According to the current knowledge, based on previous studies and considering the positive performance of the prototype as shown by the tests, 1.2 MPa is suggested as an acceptable parameter of compressive strength for the EVA block. 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 processo de avaliação de desempenho estrutural do pré-moldado proposto. As avaliações de cargas de ocupação e impactos nas paredes do protótipo construído com blocos EVA foram realizadas, através de ensaios (impactos de corpos mole e duro, solicitações transmitidas por fechamentos bruscos de porta e cargas provenientes de peça suspensa) que procuram simular situações acidentais e normais de uso de uma edificação. No processo de construção do protótipo observaram-se facilidades no uso dos blocos EVA, que são importantes na perspectiva da redução de resíduos de construção e demolição. À luz do conhecimento atual, baseando-se nos estudos anteriores e considerando-se o bom desempenho do protótipo, verificado nos ensaios realizados, sugere-se 1,2 MPa como parâmetro aceitável de resistência à compressão para o bloco EVA.
