Evolution of the hydration in cements with additions

open access: yesMateriales de Construccion, 2002
In this paper, the hydration mechanism of portland cement pastes with limestone, quartz and natural pozzolan (80/20 weight) was analized. The techniques used were nonevaporable water content, pozzolanic activity and X-ray diffraction.

Kinetics of lime/bentonite pozzolanic reactions at 20 and 50 °C: Batch tests and modeling

open access: yes, 2014
International audienceThe effects of duration (1-100 days) and temperature (20 and 50 °C) were assessed from batch tests for Ca-bentonite mixed with 10 wt.% lime. The pozzolanic processes were monitored over time by 29Si NMR (Cement Concr. Res. 42, 2012),

Solidification/stabilisation of soil contaminated with metal: a review [PDF]

open access: yes, 2008
Solidification/stabilisation (S/S) is generically defined as a chemical and physical alteration technique of reducing the mobility as well as solubility of contaminants in wastes in order to convert them into chemically inert form.

Using metakaolin to improve the compressive strength and the durability of fly ash based concrete [PDF]

open access: yes, 2011
Partial replacement of Portland cement by pozzolanic and cimentitious by-products or mineral additions that allow for carbon dioxide emission reductions is a major issue in the current climate change context.
