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 ...
Effectiveness of shrinkage-reducing admixtures on Portland pozzolan cement concrete
(CONSEJO SUPERIOR INVESTIGACIONES CIENTIFICAS-CSIC, 2005)
Drying shrinkage causes tensile stress in restrained concrete members. Since all structural elements are subject to some degree of restraint, (trying shrinkage is regarded to be one of the main causes of concrete cracking.
High-strength self-curing low-shrinkage concrete for pavement applications
(TAYLOR & FRANCIS LTD, 2010)
High-performance concretes (HPC) that are designed to possess high early strength, self-curing capabilities and low shrinkage may potentially improve rigid pavement performance. A multi-scale experimental programme examined ...
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 ...
Updating concrete drying-shrinkage prediction models for local materials
(AMER CONCRETE INST, 2004)
This paper addresses the need to update existing concrete drying-shrinkage prediction models to reflect local materials. The experimental program was carried out using eight concrete mixtures of similar strength, manufactured ...
Application of internal curing for mixtures containing high volumes of fly ash
(ELSEVIER SCI LTD, 2012)
This paper focuses on testing performed on mixtures that would be consistent with the mortar portion of a concrete bridge deck mixture for many state departments of transportation. In this work a relatively large percentage ...

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
