Abstract: Described herein are cementitious composite materials incorporating carbon nanostructures (e.g., nanotubes, nanoplatelets, nanoribbons) that are employed as amendments (i.e., admixtures or additives) to cementitious waste forms as a means to enhance radionuclide and hazardous waste (e.g., heavy metals, toxic organics) retention wherein the incorporation of well-dispersed carbon nanostructures yields more effective waste forms through the resulting modification of the cementitious composite nano-, micro-, and meso-structure (e.g., hindering the infiltration of oxygen and the leaching of waste), and the chemical interactions between chemically-affine waste molecules and the amended cementitious composite.

Abstract: Amino acid-containing carbonated composites of silicate-containing cementitious materials and methods of making the same, are disclosed. The carbonated composites contain polymorphs of CaCO3, that are controlled in terms of type (i.e., relative proportion) and size when compared to the same composites formed without amino acids and show improved mechanical properties. Methods of making carbonated silicate-containing cementitious materials with improved properties include supplementing a silicate-containing cementitious material with one or more amino acids prior to carbonation, in effective amounts to confer to the resulting carbonated composite material has one of the following properties when compared to composite materials cured under the same conditions in the absence of the one or more amino acids.

Abstract: A method for ecological filling with mixed coal gangue and fly ash includes the following steps: S1: construction of a double-impermeable base layer: leveling a pit or gully, laying a fly ash-based cementitious material, compacting and curing; spraying a layer of polymer waterproof coating on a surface of the fly ash-based cementitious material, and fully curing to obtain a double-impermeable protective structure; S2: three-dimensional layered filling: dumping coal gangue and fly ash in sequence on the double-impermeable protective structure formed in S1, where the coal gangue and the fly ash are three-dimensionally layered and well graded; the coal gangue is coal gangue after coal washing, which is used as an aggregate; the fly ash is used as a filler and cementitious material to achieve a compact filling structure; and S3: rolling: rolling by a roller after the three-dimensional layered filling.
