Resumo: Ash occupies a prominent place among agro-industrial wastes, as it is derived from energy generation processes. Several types of ash have pozzolanic reactivity, and might be used as replacement material for cement, resulting in less energy waste and lower cost. This work aimed to investigate the physical and chemical properties of the cashew nut shell ash (CNSA), by performing the following measurement tests: chemical analysis, bulk density, specific mass, leaching and solubilization process, X-ray diffraction (XrD), specific surface area (BET) and pozzolanicity analysis with cement and lime. The results indicate a low reactivity of CNSA and the presence of heavy metals, alkalis and phenol.

Sabe-se que muitas dessas cinzas possuem reatividade pozolânica, podendo ser utilizadas como adição mineral em matrizes de cimento Portland. O presente estudo tem como objetivo investigar as características físicas e químicas da cinza da casca da castanha de caju (CCCC), por meio dos seguintes ensaios: análise química, massa unitária, massa específica, extratos lixiviado e solubilizado, difratometria de raios X (DrX), superfície específica (BET) e análise da pozolanicidade com o cimento Portland e com a cal. O conjunto de análises deste trabalho indica a restrição ao uso da CCCC em matrizes cimentícias em função da baixa reatividade com o hidróxido de cálcio (CH) e dos altos teores de álcalis, dos metais pesados e do fenol detectados nessa cinza.Universidade Estadual De Maringá2010-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioncaracterizaçãoapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/743410.4025/actascitechnol.v32i4.7434Acta Scientiarum.
