The aim of this study was to evaluate relationship between shrinkage development and early solubility of two commonly used luting materials, a self-adhesive cement (GCem chemical and light cured) and composite resin (Tetric). Linear displacement, shrinkage forces and leaching of UDMA from specimens immersed in 75% ethanol/25% water were measured. The least amount of linear shrinkage (33.0±2.9 µ...

Recycling solid waste in cement-based materials cannot only ease its load on the natural environment but also reduce carbon emissions of building materials. This study aims to investigate effect recycled glass powder (RGP) early-age mechanical properties and autogenous shrinkage cement pastes, where is replaced by 10%, 20% 30% RGP. In addition, microstructure nano-mechanical paste with differen...

Ultra-High Performance Concrete (UHPC) exhibits high autogenous shrinkage (AS) which significantly increases the risk of early age cracking. To predict risks cracking environmentally friendly CEM III-based UHPC, a numerical model originally developed for crack assessment ordinary concrete, has been further and applied on demonstration wall with cracking, cast non-deforming slab. The design was ...

The crack resistance of face slab concretes to various shrinkages is crucial for the structural integrity and normal operation concrete-faced rockfill dams (CFRDs). In this work, effects fly ash with four dosages (i.e., 10%, 20%, 30% 40%) on drying shrinkage, autogenous shrinkage cracking concrete were studied. Besides, difference in behavior due addition was revealed from viewpoint pore struct...

Early-age drying (immediately after casting) of mortars and the corresponding plastic shrinkage were studied using bimodal neutron/X-ray computed tomography. This novel, correlative 3D imaging mode enabled studying simultaneously without any source spurious perturbation water migration loss processes together with deformations due to shrinkage. Bimodal opens up new possibilities for dynamic cou...

Fresh concrete is characterized by numerous processes taking place simultaneously such as settlement, hydration, early-age cracking and shrinkage. Those have a strong impact on the strength durability, hence monitoring material at an early stage essential to ensure required performance. Acoustic Emission (AE) non-destructive, highly sensitive technique that records elastic waves propagating thr...

Abstract In this study, glass wool waste was utilized by means of alkali-activation with blast furnace slag. Reaction kinetics, workability, mechanical properties and autogenous shrinkage alkali-activated slag were comprehensively studied. Results indicated an optimal modulus (SiO2/Na2O) the activator related to a long enough setting time high reaction degree paste. The incorporation as partial...

Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these problems. At an early age, the absorbed water by the SAPs may be used to mitigate autogenous and plastic shrinkage. The formed macro pores may...
