13. Application of X-ray diffraction and Rietveld method in Portland Cement study / Aplicação da difração de raios-X e método de Rietveld no estudo de Cimento Portland
O projeto desenvolvido enfocou a aplicação da difração de raios-X e método de Rietveld (DRX-Rietveld) na caracterização e quantificação do Cimento Portland, constituindo-se em contribuição pioneira sobre o tema em âmbito nacional. Foram estudadas amostras de pozolanas naturais e artificiais, subprodutos industriais de grande disponibilidade na in

14. A utilização da cinza da casca de arroz de termoelétrica como componente do aglomerante de compósitos à base de cimento Portland / The use of thermoeletrical rice husk ash as component of mixtures based in cement agglomerate
Industrial residues, such as pozzolan, can be incorporated in concretes as a solution for polluter refuses, according to sustainable principles. The objective of this work it is to discuss and analyze the use of rice thermoeletrical industry residue, the rice rusk ash (RHA), as mineral addition in durable concretes. The RHA can be used to increase the compre

15. Utilização de pozolanas em compósitos de cimento reforçados com fibras de celulose e PVA. / Pozzolan utilization in cement composites reinforced with celullose and PVA fibers.
Composites reinforced with natural fibers are a good asbestos fibercomposites replacement material, as a result of the great natural fiber avaibility such as coco nut, sisal and cellulose. Durability aspects need to be improved, like the decrease of fiber resistance in alkaline environment causing the loss of mechanical properties of the composites. An alter

16. Potencial da cinza do bagaço da cana-de-açúcar como material de substituição parcial de cimento Portland / Potential of the sugarcane bagasse ash as a partial replacement material for cement Portland
This study was carried out to evaluate the potential of the sugarcane bagasse ash (CBC) as partial replacement material for the Portland cement in mortar. A residue generated at the Jatiboca sugar mill located in Urucânia county-MG was used as CBC. The use of the sugarcane bagasse as an ash source for mineral addition into cement-based materials is subjecte

17. Estudo do aproveitamento de resíduos de cerâmica vermelha como substituição pozolânica em argamassas e concretos
Portland cement based materials have great potential for providing good waste immobilization solutions, which are both cost effective and also promotes the sustainable development of modern industrial activities. Indeed, several industrial wastes have successfully been used in constructions worldwide, most of them from steel and energy manufacturing processe
