Realkalisation and electrochemical chloride removal techniques, developed for rehabiliting carbonated and chloride-containing structures, are presented. Electrolysis and electromigration mechanisms and consequences as well as electrochemical conditions at the reinforcement surface are discussed and compared with catho…
Delayed ettringite formation (DEF) is the term used to describe expansion of some heat cured portland cement concretes. Although meaningful progress has been made, the exact mechanism of the expansion itself is not entirely understood. The ettringite reformation is enabled, primarily, by thermal decomposition of ettri…
This paper covers studies made using different mixes for cellular concrete variating silica sand, vulcanic glass and aluminium powder contents. Studies on compressive strenght, dry density and X-ray diffraction are performed on autoclave cured cellular concrete, concluding that best results are attained when vulcanic…
Abstract A series of conducting polyaniline/poly(butadiene‐co‐styrene‐co‐2‐vinylpyridine) (PBSP) latex composites was prepared by polymerization of aniline in the presence of PBSP latex. The mass loading of polyaniline in the composite latex can be controlled by varying the PBSP latex/aniline charging ratio and oxidan…
A differential thermal analysis (DTA) method has been developed that identifies and distinguishes surface and internal (volume) crystallization in glasses. This method is fast, convenient, and requires only a small quantity of sample, ∼500 mg, to identify the dominant crystallization, surface versus internal, in the g…
ABSTRACT Cross‐sections of cooked muscle were prepared using a vibrating microtome. Average fiber cross‐sectional area was measured by confocal scanning laser microscopy and image analysis. Fiber cross‐sectional area significantly correlated with sensory perception of firmness (r = ‐0.91, p < 0.01). Sensory firmnes…
Classical continuum descriptions of material degradation may cease tobe mathematically meaningful in case of softening-induced localisationof deformation. Several enhancements of conventional models have beenproposed to remove this deficiency. The properties of two of theseso-called regularisation methods, the non-loc…
It is found that the proton is strongly absorbed in heavily Sc-doped ${\mathrm{SrTiO}}_{3}$. Neutron-diffraction measurements were performed using single crystals. The O-H distance is found to be about 1.2 \AA{} and the proton concentration is estimated to be about 2 mol % for ${\mathrm{SrTi}}_{0.98}$${\mathrm{Sc}}_{0…
We present the results of a molecular dynamics computer simulation in which we investigate the dynamics of silica. By considering different system sizes, we show that in simulations of the dynamics of this strong glass former surprisingly large finite size effects are present. In particular, we demonstrate that the re…
Inelastic neutron scattering and neutron diffraction were used to study a single crystal of the ${\mathrm{Ni}}_{2}$MnGa shape memory Heusler alloy in a wide temperature range covering the parent phase ($T>{T}_{1}=260$ K), a premartensitic phase (${T}_{1}>T>{T}_{M}$), and a martensitic ($T<{T}_{M}=220$ K) p…
Abstract Illite polytype quantification allows the differentiation of diagenetic and detrital illite components. In Paleozoic shales from the Illinois Basin, we observe 3 polytypes: 1M d , 1M and 2M 1 . 1M d and 1M are of diagenetic origin and 2M 1 is of detrital origin. In this paper, we compare experimental X-ray di…
