High-volume fly ash has been widely used in concrete to reduce the cost and environmental
impact of producing cements. However, the effect of high temperature on cement-based …

In the present work the effect of concrete incorporation with two types of nano-lead
compounds on its γ-ray shielding characteristics is investigated. The concrete samples were …

The effects of high proportions of fly ash in cement-paste composites for use in low-strength
applications for sustainable ecological products were investigated. Pore volume is an …

The potential of positron annihilation spectroscopy (PAS) in the study of light alloys is
illustrated with special regards to age-hardening, severe plastic deformation, fatigue and …

Fe–Cu binary alloys are often used to mimic the behaviour of reactor pressure vessel steels.
Their study allows identifying some of the defects responsible for irradiation-induced …

The sensitivity of positron annihilation characteristics to changes in the molecular packing in
network-forming polymers has been demonstrated since the early 1980s. Positron …

Porous structure evolution in functional humidity-sensitive MgAl 2 O 4 spinel ceramics
prepared at different sintering temperatures is studied. It is shown that the increase in …

This paper investigates the viability of using waste glycerin (WG), industry lignin (IL) and
cane molasses (CM) used as grinding aids in blended cement, performance of the blended …

Extended defects in insulating nanoporous MgAl2O4 spinel‐type ceramics which trap
positrons are characterized by positron annihilation lifetime spectroscopy before and after …

The water-sensitive positron trap** modes in nanoporous MgAl 2 O 4 ceramics with a
spinel structure are studied. It is shown that water-sorption processes in magnesium …
