In this study, the main emphasis is placed on the development and characterization of alkali-activated binders completely produced by the use of mixed construction and demolition waste (CDW)-based masonry units as aluminosilicate precursors. Combined usage of precursors was aimed to better simulate the real-life cases since in the incident of construction and demolition, these wastes are anticipated to be generated collectively. As different masonry units, red clay brick (RCB), hollow brick (HB) and roof tile (RT) were used in binary combinations by 75-25%, 50-50% and 25-75% of the total weight of the binder. Mixtures were produced with different curing temperature/periods and molarities of NaOH solution as the alkaline activator. Characterization was made by the compressive strength measurements supported by microstructural investigations which included the analyses of X-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDX). Results clearly showed that completely CDW-based masonry units can be effectively used collectively in producing alkali-activated binders having up to 80 MPa compressive strength provided that the mixture design parameters are optimized. Among different precursors utilized, HB seems to contribute more to the compressive strength. Irrespective of their composition, main reaction products of alkali-activated binders from CDW-based masonry units are sodium aluminosilicate hydrate (N-A-S-H) gels containing different zeolitic polytypes with structure ranging from amorphous to polycrystalline.

This work deals with the conditioning of tritiated industrial oils in the context of nuclear wastes that are still deprived of an appropriate treatment solution. The strategy consists in directly conditioning model mineral oils in alkali-activated materials (AAM), additionally functionalized with a γ-MnO2/Ag2O hydrogen/tritium getter. Geopolymer (GEO) and alkali-activated blast furnace slag (AABFS) are considered as AAM. In the presence of surfactants, the oil was successfully emulsified (small and homogeneous droplets) in both types of AAM. Two surfactant mechanisms are distinguished acting by: 1) decreasing the interfacial tension or 2) promoting oil-particles interactions. Mechanism 1 should be favored if workability of fresh mixtures is required, while mechanism 2 should be targeted to provide a better confinement of oil owing to strong oil-particles interactions. After curing, AAM-OIL composites are obtained. There is no influence of the oil and surfactants on the setting time and strength development of AAM. The main reaction products (C-A-S-H in AABFS and N-A-S-H in GEO) are not impacted. However, the addition of surfactants leads to increased porosity of AAM due to air bubbles stabilization. AAM-OIL composites immobilizing 20%vol. of oil all have compressive strengths higher than 20 MPa, which is a more than the 8 MPa required from ANDRA. Overall, according to both fresh and hardened states observations, GEO exhibit higher performances for the immobilization of oil than AABFS. The efficiency of the γ-MnO2/Ag2O getter was assessed in AAM via in-situ hydrogen production by gamma irradiations or magnesium corrosion. Both types of experiments agree to the higher performances of the getter in GEO than in AABFS. This is explained by reducing sulfur species present in AABFS, which react with the oxidizing getter components. Finally, wetting measurements demonstrated that industrial oils have an excellent affinity for GEO, testifying that long-term water seepage is not likely to dislodge them from GEO-OIL composites. In the context of nuclear waste management, GEO functionalized with γ-MnO2/Ag2O getter appears as a promising option for disposal of tritiated oils. However, additional investigations of HTO confinement need to be performed that could renew the interest of using AABFS
