Resumo


As argamassas de revestimento foram preparadas substituindo parcialmente areias convencionais, nomeadamente areia grossa (AG) e areia fina (AF), por diferentes dosagens de cinzas secas de biomassa (CP) e cinzas volantes (CV). 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.
