“…For example, a factor 5 is reached for D app,Cl of CEM I MK (25 %) obtained by migration and diffusion tests. In general, it is considered [7] that D app, Cl obtained by the migration depends only on the porous network. Indeed, during the migration test, interactions (between chloride and cementitious matrix) are very weak and can be often neglected.…”

The use of calcined clay, in the form of metakaolin (MK), as a pozzolanic constituent for concrete has received considerable attention in recent years, due to the lower CO 2 emission of this supplementary cementitious material compared to the production of a classic portland cement. Furthermore, concretes incorporating MK show some improve durability properties. In this paper, the durability of concretes and cement pastes with MK as partial replacement of cement (10 and 25 %) has been investigated in comparison with CEM-I materials one. Water porosity, chloride migration and diffusion, electrical resistivity and natural and accelerated carbonation tests have been performed. In addition, microstructural study is performed to better understand the results on the durability indicators. The cement pastes microstructure was characterized not only by usual techniques such as mercury intrusion porosimetry, XRD and TGA-DTA, but also by 29 Si and 27 Al NMR spectroscopy. For example, Friedel's salt (chemical binding) has been quantified by 27 Al NMR spectroscopy and XRD on cement paste. In addition, the progress of the durability properties for various water curing times has been investigated. Results show an evolution of the properties, as a function of the cement replacement degree by MK, such replacement increases durability against chloride penetration but decreases resistance to carbonation. The aluminate phases equilibrium is modified in concrete with metakaolin in comparison with a CEM-I one. Both chemical and physical chloride binding increases with MK replacement. In addition, since portlandite quantity decreases in cement materials with MK, these materials are less resistant to carbonation process for a same exposure condition (time and CO 2 concentration).

“…Moreover, similar x d values are found for M50 and BO, as expected from their similar mix-designs (in particular, W/C ≈ 0.50), 28 day c.s. (see Section 2.1), and effective chloride diffusion coefficients (see [40]). Furthermore, the same ranking of the mixtures is obtained in field and in lab (when considering LR59 ≈ M75 and B70SF ≈ M75SF, see Section 2.1).…”

Long-term studies under various natural exposure conditions are still needed in order to understand and quantify ageing and durability of concrete structures, in particular in the case of mixtures which incorporate supplementary cementitious materials (e.g. fly ash). With this purpose, a large-scale and long-term experimental program was initiated a lot of years ago by the LPC network within the framework of the French national project "BHP 2000." From then, further researches have been carried out in order to complement the program. The present paper focuses on chloride penetration in concrete samples in lab conditions and in reinforced concrete (RC) structural elements exposed for 10 years to two different natural environments (tidal zone in marine environment, as well as road and cold environment). Numerous mixtures (28 day cylinder compressive strengths ranging from 20 to 130 MPa) were studied in these various conditions, e.g. high-performance materials with or without silica fume (SF), as well as normal-strength fly-ash (FA) concretes. Carbonation and chloride penetration depths, along with total chloride concentration and degree of saturation profiles, have been measured on the RC structural elements and analyzed as a function of the exposure conditions and of the mix-parameters. In addition, the chloride data have been compared to lab results. Apparent chloride diffusion coefficients, as well as chloride binding isotherms and capacities, have also been assessed on these structural elements and compared to lab results. Good consistence between results in field and in lab conditions has been highlighted, except when carbonation has affected the field results. In addition, the good performance of SF-HPCs and mature FA concretes has been pointed out in the tested outdoor conditions, as well as that of the mature ground granulated blast furnace slag concretes tested in lab.
