Journal ArticleDOI
Development of porosity of cement paste blended with supplementary cementitious materials after carbonation
TL;DR: In this paper, the pore volume and size distribution of capillary pores were determined using MIP to determine the influence of carbonation of C-S-H with fly ash and blast furnace slag.
Journal ArticleDOI

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.
Journal ArticleDOI
Cementitious properties and hydration mechanism of circulating fluidized bed combustion (CFBC) desulfurization ashes
TL;DR: In this article, the self-cementitious properties and pozzolanic reactivity of CFBC desulfurization ashes (CFBCA), modified CFBCAs (MCFBCAs), and pulverized fuel fly ash (PFA) are investigated.
Journal ArticleDOI
Utilization of modified CFBC desulfurization ash as an admixture in blended cements: Physico-mechanical and hydration characteristics
TL;DR: In this paper, the particle size distributions of modified CFBC desulphurization ashes were effectively optimized and its water demand was obviously decreased, while the strength of blended cements increased significantly with the increase of grinding time, the strength increased due to the activation effects of the modifiers.
Journal ArticleDOI
Prediction of the autogenous shrinkage and microcracking of alkali-activated slag and fly ash concrete
TL;DR: In this article, a new numerical approach is developed to predict the autogenous shrinkage of alkali-activated slag and fly ash concrete from the experimental results on corresponding paste.
