(Acta Scientiarum: Technology, 2010-07-01) [Artigo]
Analysis of experimental interlocking blocks of concrete with addition of residues of process the tires retreading production. With the population growth in recent years, industry in general has adjusted itself to resulting ...
Estudo das propriedades mecânicas do concreto com adição de cinza de casca de arroz
(Materia-rio de Janeiro, 2015-01-01) [Artigo]
The thermal curing is a process used to accelerate the hydration reactions of the Portland cement in mortar and concrete elements, in order to achieve gains in mechanical strength at early ages, since the temperature acts ...
New method to assess the pozzolanic reactivity of mineral admixtures by means of pH and electrical conductivity measurements in lime:pozzolan suspensions
(Materiales De Construccion, 2014-01-01) [Artigo]
A very simple method based on electrical conductivity and pH measurements was proposed for assessing reactivity of pozzolans. Calcium hydroxide: pozzolan water suspensions were monitored by means of measurements of electrical ...
Optimum Use of Sugar Cane Straw Ash in Alkali-Activated Binders Based on Blast Furnace Slag
(Journal Of Materials In Civil Engineering, 2018-06-01) [Artigo]
Alkali-activated binders (AABs) are a material obtained from the combination of a solid precursor and an alkaline activating solution. In this study, one solid precursor used was blast-furnace slag (BFS) and the other was ...
Cinza de bagaço de cana-de-açúcar (CBC) como adição mineral em concretos para verificação de sua durabilidade
(Revista Materia, 2015-10-01) [Artigo]
The sugar-alcohol sector has been expanding in recent years, mainly by the advent of bioenergy. In Brazil, the production of sugarcane is increasing in areas before used for extensive cattle and other important crops, such ...
Rendimiento de morteros producidos con la incorporación de ceniza de bagazo de caña de azúcar
(Revista Ingenieria de Construccion, 2014-01-01) [Artigo]
This paper presents the technical feasibility of using ash in mortars, from burning sugarcane bagasse, to generate power as a mineral admixture. The sugarcane bagasse ash (SCBA) underwent chemical characterization and x-ray ...
