Sulphate resistance of air entrained mortars with admixture of fly ashes

open access: yesBudownictwo i Architektura, 2015
The effects of entrained air on sulphate resistance of fly ash blended cements mortars long term immersed in Na2SO4 solution were investigated. The expansion strains and decrease in strength of air entrained mortars were faster than those of non-air ...

Viability of ceramic residues in lime-based mortars [PDF]

open access: yes, 2013
3rd Historic Mortars Conference, 11-14 September 2013, Glasgow, ScotlandWhen we approach the subject of construction and rehabilitation of buildings we necessarily must think about external wall coatings as they are the elements more exposed to climate ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

open access: yesAdvanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Fire tests on polyester polymer mortars [PDF]

open access: yes, 2003
Composite materials made from organic matrices are generally combustible. It is necessary to determine in each case their behaviour under fire and determine whether they fulfil the requirements of the applicable standards in order to match each material

Mechanical Characterisation of Gypsum-Based Passive Fire Protection Mortars with Micro and Nano Silica Particles

open access: yesApplied Sciences
Steel structures are vulnerable to fire due to the degradation of their mechanical properties at high temperatures, making it necessary to protect them when exposed to high temperatures. This paper presents the results of an experimental research work to

A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.
