Polymerization stress, shrinkage and elastic modulus of current low-shrinkage restorative composites
(ELSEVIER SCI LTD, 2010)
Objective. To compare currently available low-shrinkage composites with others regarding polymerization stress, volumetric shrinkage (total and post-gel), shrinkage rate and elastic modulus. Methods. Seven BisGMA-based ...
Do Low-shrink Composites Reduce Polymerization Shrinkage Effects?
(SAGE PUBLICATIONS INC, 2011)
Progress in polymer science has led to continuous reduction of polymerization shrinkage, exemplified by a new generation of ""low-shrink composites"". The common inference that shrinkage stress effects will be reduced in ...
Mechanical properties, drying and autogenous shrinkage of blast furnace slag activated with hydrated lime and gypsum
(ELSEVIER SCI LTD, 2010)
This article reports the characteristics of blast furnace slag (BFS) pastes activated with hydrated lime (5%) and hydrated lime (2%) plus gypsum (6%) in relation to compressive strength, shrinkage (autogenous and drying) ...
VARIATION IN ANISOTROPIC SHRINKAGE OF PLANTATION-GROWN PINUS RADIATA WOOD
(Universidad del Bío-Bío, 2008)
Drying and autogenous shrinkage of pastes and mortars with activated slag cement
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Activated slag cement (ASC) shows significantly higher shrinkage than ordinary Portland cement agglomerates. Cracking generated by shrinkage is one of the most critical drawbacks for broader applications of this promising ...
Study of shrinkage porosity in spheroidal graphite cast iron
(Taylor & Francis, 2016-03-29)
This study aims at identifying the relationship between the shrinkage cavities and the solidification structure in spheroidal graphite cast iron. Cast samples specially designed to contain shrinkage cavities were used. The ...
Polymerization-induced shrinkage of dual cements through different thicknesses of ceramic materials
(Facultad de Odontología, 2012)
Shrinkage Assessment Of Low Shrinkage Composites Using Micro-computed Tomography
Network structures of Bis-GMA/TEGDMA resins differ in DC, shrinkage-strain, hardness and optical properties as a function of reducing agent
(ELSEVIER SCI LTD, 2011)
Objectives. To evaluate the influence of different tertiary amines on degree of conversion (DC), shrinkage-strain, shrinkage-strain rate, Knoop microhardness, and color and transmittance stabilities of experimental resins ...
Retratibilidade da madeira de Pinus caribæa var. hondurensis e de Eucalyptus grandis e suas relações com a umidade e densidade
It had been studied the dimensional variations Pinus caribæa var. hondurensis and Eucalyptus grandiswood, emphasizing the axial, radial, tangential and volumetric shrinkage. The results had shown that the volumetric shrinkage ...
