Journal ArticleDOI
Leaching of cement: Study of the surface layer
TL;DR: Leaching of cement pastes shows that the properties of the surface layer are similar whether or not the cement paste contains slag as mentioned in this paper, and substantial amounts of calcium, and smaller amounts of silicon, are leached out.
Journal ArticleDOI
Long-term performance of cement paste during combined calcium leaching–sulfate attack: kinetics and size effect
TL;DR: In this article, the authors present experimental results obtained on cement paste samples (water/cement ratio of 0.4) subjected to a low-concentration (15 mmol/l) external sulfate attack during several weeks.
Journal ArticleDOI
Physico-chemical investigation of clayey/cement-based materials interaction in the context of geological waste disposal: Experimental approach and results
TL;DR: In this article, experiments were conducted on the diffusion of solutes constituting those porewaters in a confined clay/cement composite system using cells and the test temperature was set at 25°C and 2, 6 and 12 months.
Journal ArticleDOI
On the physico-chemical evolution of low-pH and CEM I cement pastes interacting with Callovo-Oxfordian pore water under its in situ CO2 partial pressure
A. Dauzeres,A. Dauzeres,P. Le Bescop,Céline Cau-dit-Coumes,F. Brunet,Xavier Bourbon,Jussi Timonen,Mikko Voutilainen,Laure Chomat,Paul Sardini +9 more
TL;DR: In this paper, the authors compared the physico-chemical behaviour of a low-pH material with a CEM I cement paste, both being subjected to leaching by an aqueous solution.
Journal ArticleDOI
Effect of an accelerated chemical degradation on water permeability and pore structure of cement-based materials
TL;DR: In this paper, the results showed that the accelerated ammonium nitrate leaching was governed by a diffusion process and was responsible not only for portlandite dissolution but also for CSH decalcification.
