Project description
Improving cementitious thermal conductivity
Stricter EU regulations on buildings increased the use of high-insulating materials such as expanded polystyrene and extruded polystyrene. As the efficient use of a porous cementitious system relies on its air content, lightweight concretes present higher thermal insulation performance. However, their very high density prevents their use. Heated-based thermal energy storage is an innovative solution that relies on the effective use of phase change materials (PCMs). Since existing microencapsulated PCMs for building applications present very low thermal conductivity, it’s necessary to blend graphene in the cementitious matrix and the microencapsulated PCMs in order to achieve increased thermal conductivity. The EU-funded NRG-DEAL project will improve cementitious lamellae of concrete foams for building insulations.
Objective
Thermal insulation of construction and building elements has become the most important measure to enhance energy
savings in new and existing building stock. Stricter regulations (such as 2019/2021 EU Buildings Directive) have led to the
use of huge thicknesses of standard insulation, almost always EPS and XPS.
An efficient use of a porous cementitious system as a thermal insulation material depends mainly on its air content.
Lightweight concretes have a better thermal insulation capacity than regular-weight ones; however, their use is not efficient
enough due to their still too high density.
The problem with these insulations is that they store heat/cold sensibly (variation of the body temperature). An innovative
solution would be the employment of a latent heat based Thermal Energy Storage, using the phase transition occurring in
part of the insulation. During the phase transition, the insulation material will absorb/release energy at constant temperature,
increasing the system efficiency. A maximization of the synergetic interplay between thermal conductivity and the potential to
store/release energy into components of the building envelope can be achieved by an effective use of Phase Change
Materials.
A disadvantage of using commercially available Microencapsulated PCMs in building applications is their very low thermal
conductivity. To counteract it, graphene can be blended in both the cementitious matrix and the MPCMs in order to achieve
a targeted increase in thermal conductivity. Graphene addition also allows voluntary resets of the MPCM by means of an
external intentional potential difference, due to the enhanced composite’s electrical conductivity and magnetic permeability.
The proposed project deals with the improvement of cementitious lamellae of concrete foams for buildings insulations.
MPCMs addition and graphene doping of both cement paste and MPCMs will enhance thermo-electrical properties of this
cutting-edge eNeRGy material.
