Work Packages (WP)

  • WP1

    - Optimization of mixing variables

    - Aggregates, by analysing the following variables: (i) Chemical and mineral state and (ii) Shape and morphoplogy.
    - Suplementary Cementitious Materials, by analysing the following variables: (i) the use of nanoaddition & nanofibers and (ii) the use of appropriate wastes (slag, Fly-Ash).
    - Cement Particle Size Distributions (PSD).

    - Characterization of the samples

    - Structural and mechanical characterization: XRD, SEM, FTIR, Porosities, BET, Tensile and Compressive strengths.
    - Thermal characterization: Heat Capacities, Thermal diffusivity, thermogravimetric analysis, etc

    - Modelling and design

    - Implementation and use of a Heat Transport Lattice Boltzmann model over multiscale OPCs structures. These multi-scale structures of the OPC composite will be modeled following the already developed multi-scale protocols

  • WP2

    - Optimization of mixing variables, variables like aggregates, suplementary cementitious materials and cement Particle Size Distributions (PSD).


    - Characterization of the samples, structural, mechanical and thermal properties.


    - Modelling and design

    - Adapt the CODICE codes to include the recently proposed nanostructure of geopolymers based on defected sodalites.
    - Use of the Heat Transport Lattice Boltzmann model developed in past tasks

  • WP3

    - Optimization of mixing variables, variables like Aggregates, Suplementary Cementitious Materials and Cement Particle Size Distributions (PSD).


    - Characterization of the samples, structural, mechanical and thermal properties.

  • WP5

    - Detailed modelling

    - A simulation model of being able to  describe the thermal behavior of a regenerative storage (isotropic solid based storage), in  order to optimizing the concept design according to material’s features.


    - Simplified modelling

    - A model able to provide the main outputs of a storage system integrated in a STE plant.
