1. Evaluation of the use of silica-alumina refractory waste as a supplementary cementitious material
Abstract The use of supplementary cementitious materials (SMCs) is one of the three essential factors for the sustainability of the cement industry. To reduce CO2 emissions, several studies have introduced new methods for the utilization of industrial wastes such as the addition into cementitious materials. The objectives of this study were to chemically and

2. Study of the Influence of Chemical Composition on the Pozzolanicity of Soda-lime Glass Microparticles
The use of residues, in partial or total substitution of aggregates or binders in concrete, presents interesting possibilities for obtaining eco-efficient concretes. Research has investigated the use of glass residue in Portland cement composite, whether as an aggregate or a supplementary cementitious material. However, there is still no consensus on the inf

3. 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

4. The use of swine deep bedding ash as partial substution of Portland cement. / Aproveitamento das cinzas da queima da cama sobreposta de suínos para substituição parcial do cimento Portland.
A sustentabilidade das regiões de produção intensiva de suínos depende de destinos alternativos para os resíduos gerados. A calcinação da casca de arroz pode gerar sílica vítrea para substituição parcial de aglomerantes comerciais. A utilização de cinzas de casca de arroz como material pozolânico para argamassas e concretos tem merecido atenç�
