Microstructural and mechanical properties of marine soft clay stabilized by lime-activated ground granulated blastfurnace slag
TL;DR: In this paper, quicklime and hydrated lime were used to activate ground granulated blastfurnace slag (GGBS), a byproduct of the steel industry, for stabilization of marine soft clay in comparison to Portland cement.

Durability-related performance of concrete containing fine recycled aggregates from crushed bricks and sanitary ware
TL;DR: In this paper, an experimental study using aggregates sourced from crushed red clay ceramic bricks (CBAs) and sanitary ware (SWA) is presented, where different concrete mixes were produced where the fine natural aggregate fraction was partially or fully replaced by each of these materials.

The role of the alumina content of slag, plus the presence of additional sulfate on the hydration and microstructure of Portland cement-slag blends
TL;DR: In this article, the effects on composite cements of the aluminium content of slag, plus that of additional sulfate, have been investigated, showing that adding slag changed the hydration kinetics of the clinker phases.

Hydration of alkali-activated slag: thermodynamic modelling
TL;DR: In this paper, the composition of solid and liquid phases of alkali-activated slag systems was investigated by thermodynamic modelling, which predicts the formation of C(A)−S−H, stratlingite and hydrotalcite.

The Role of Calcium Carbonate in Cement Hydration
TL;DR: In this paper, it is shown by experiment and calculation that much, if not all, of this calcite is reactive and affects the distribution of lime, alumina and sulfate and thereby alters the mineralogy of hydrated cement pastes.
Journal ArticleDOI
Thermodynamic modelling of the hydration of Portland cement
TL;DR: In this paper, a thermodynamic model is developed and applied to calculate the composition of the pore solution and the hydrate assemblage during the hydration of an OPC.

Thermodynamic investigation of the CaOAl2O3CaSO4H2O system at 25°C and the influence of Na2O
D. Damidot,F.P. Glasser +1 more
TL;DR: In this article, the CaOAl2O3CaSO4H2O system at 25°C has been investigated by calculations on the equilibrium solubility surfaces of AH3, C3AH6, CH, C 6 A S 3 H x, C 4 A S H x and gypsum.
