Acesso em:.https://repositorio.ufpa.br/handle/2011/2594This work aims to evaluate the possibility of use of waste obtained from the combustion of coal in fluidized bed boilers, an alumina refinery in Pará state. In this context, we evaluated the incorporation of fly ash as pozzolan, to partially replace cement in mortar production. To that end, samples were prepared using Portland cement type CPII-E-32. The mixtures were in the ratio 4:1, that is 4 parts aggregate (silica) and 1 part of binder (cement and ash), with the inclusion of the ash of 10, 20, 30, 40 and 50 percentage with respect to the cement, beyond the mortar without addition. We defined two relation water / binder, 0,4 and 0,8. After 7 and 28 days curing time, were tested for compressive strength analysis of behavior. In addition, the mortar with the water / binder 0.8 were subjected to further analysis of X-ray diffraction, scanning electron microscopy, water absorption, porosity and bulk density, the results obtained were consistent when compared with literature data, showing that viable application of ash studied in the construction industry.porAcesso AbertoCinza de carvãoCimento PortlandArgamassaResíduos industriaisConstrução civilAlunorteCoal ashPortland cementMortarIndustrial wasteConstructionDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA QUIMICA::PROCESSOS INDUSTRIAIS DE ENGENHARIA QUIMICA::PROCESSOS INORGANICOS
