Influence of activation modes on diametral tensile strength of dual-curing resin cements.
(2005-10-01)
In metallic restorations, the polymerization of dual-curing resin cements depends exclusively on chemical activation. The effect of the lack of photoactivation on the strength of these cements has been rarely studied. This ...
Time-enhanced strength increase of an alluvial clay, typical of the northeastern region of Brazil, mixed with different cement dosages
(Univ Estadual Maringa, Pro-reitoria Pesquisa Pos-graduacaoMaringaBrasil, 2013)
Propriedades mecânicas de concretos com diferentes cimentos Portland e com cinza de casca de arroz natural e moída
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2012-06-22)
Due to high rates of emissions of carbon dioxide released in cement production, an
alternative to minimize this pollution is the use of rice husk ash in concrete as partial cement
replacement. This research aims to ...
Recycled Concretes Made with Waste Ready-Mix Concrete as Coarse Aggregate
(American Society of Civil Engineers, 2011-03)
Using waste materials for new products is a global trend undergoing rapid development. Recycling materials allows for a more efficient life cycle and contributes to environmental protection. In the construction field, this ...
Study of alternative geometry of hollow self-compacting concrete masonry blocks
(2020-01-01)
To evaluate the geometrical influence of new types of hollow concrete blocks, six different geometries were investigated using self-consolidating concrete to fabricate the blocks. The cell shapes studied were circular, ...
Physicochemical properties and dentin bond strength of a tricalcium silicate-based retrograde material
(2017-01-01)
The aim of this study was to evaluate the physicochemical properties and the apical dentin bond strength of the tricalcium silicate-based Biodentine in comparison to white MTA and zinc oxide eugenol-based cement (ZOE). ...
