TL;DR: In this article, an extensive Round Robin test programme on compressive softening was carried out by the RILEM Technical Committee 148-SSC to measure strain softening response of concrete under uniaxial compression, and the main variables in the test programme were the specimen slenderness h/d and the boundary restraint caused by the loading platen used in the experiments Both high friction and low friction loading systems were applied.

TL;DR: In this paper, a literature review, prepared by members of RILEM technical committee 281-CCC carbonation of concrete with supplementary cementitious materials, working groups 1 and 2, elucidates the effect of numerous SCM characteristics, exposure environments and curing conditions on the carbonation mechanism, kinetics and structural alterations in cementitious systems containing SCMs.

TL;DR: In this paper, the influence of these factors on peak stress, peak strain, strain softening behavior and failure localization are described and discussed, as well as their influence on failure localization.

TL;DR: The most abundant clays in the northern hemisphere are dominated by 2:1 clay minerals as discussed by the authors, however, compared to kaolinite-rich clays, these common clays have been less addressed by recent research on calcined clays.

TL;DR: In this paper, the authors used two different laser scanning systems, DAVID 3D and LEICA T-Scan, to determine and compare surface parameters at the meso level of concrete fractured surfaces.
