Resumo: Rendering mortars were prepared by replacing conventional sands, namely coarse sand (CS) and fine sand (FS), by different dosages of biomass dry bottom ash (BA) and fly ash (FA). Bottom ash was treated by sieving and washing and called treated bottom ash (TBA). All these ashes were characterized, and their effects on the physical and mechanical characteristics of mortars were studied. The dosage of water required to maintain workability of samples formulated with TBA, BA, and FA was not significantly different from the volume used to formulate a reference mortar, since the physical characteristics of the ashes used were similar to those of CS and FS. Workability, weight variation, unrestrained shrinkage and compressive strength were measured. The results showed that the pre-processing of BA and FA has to be properly characterized in the effort to reuse these materials as effective replacements of natural sand in mortars, and the associated environmental aspects should be further investigated to support this recycling strategy.

As cinzas pesadas foram tratadas por peneiração e lavagem e denominadas cinzas pesadas tratadas (CPT). Todas essas cinzas foram caracterizadas e seus efeitos sobre as características físicas e mecânicas das argamassas foram estudados. A dosagem de água necessária para manter a trabalhabilidade das amostras formuladas com CPT, CP e CV não foi consideravelmentediferente do volume utilizado para formular uma argamassa de referência, uma vez que as características físicas das cinzas utilizadas eram semelhantes às da AG e AF. Foram medidas a trabalhabilidade, variação de peso, retração livre e resistência à compressão. Os resultados mecânicos e de carbonatação mostraram que o pré-processamento de CP e CV deve ser devidamente caracterizado no esforço de reutilização destes materiais como substitutos eficazes da areia natural nas argamassas e os aspectos ambientais associados devem ser mais investigados para apoiar esta estratégia de reciclagem.UFSC - Federal University of Santa Catarina2021-04-192023-05-29T21:27:58Z2023-05-29T21:27:58Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/436210.29183/2447-3073.MIX2021.v7.n2.137-146https://repositorio.ufsc.br/handle/123456789/246583Mix Sustentável; Vol. 7 No. 2 (2021): Mix Sustentável (edição regular); 137-146MIX Sustentável; v. 7 n. 2 (2021): Mix Sustentável (edição regular); 137-1462447-30732447-0899reponame:Repositório Institucional da UFSCinstname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/4362/3594Copyright (c) 2021 Regina Célia Espinosa Modolo, Guilherme Ascensão, Luciano Senff, Francisco Roger Carneiro Ribeiro, Luis António da Cruz Tarelho, Victor Miguel Ferreira, João António Labrincha, António Santos Silva, Carlos Alberto Mendes Moraesinfo:eu-repo/semantics/openAccessModolo, Regina Célia EspinosaAscensão, GuilhermeSenff, LucianoRibeiro, Francisco Roger CarneiroTarelho, Luis António da CruzFerreira, Victor MiguelLabrincha, João AntónioSilva, António SantosMoraes, Carlos Alberto Mendes2023-05-29T21:27:58Zoai:repositorio.ufsc.br:123456789/246583Repositório InstitucionalPUBhttp://150.162.242.35/oai/requestopendoar:23732023-05-29T21:27:58Repositório Institucional da UFSC - Universidade Federal de Santa Catarina (UFSC)false
