Research

The research, placed in the 6th FP project I-SSB, concerns innovative developments in the design, production and application of gypsum plasterboards in lightweight steel structures. The research focuses on the development of mixes containing anhydrite/hemi-hydrate/cement binders, admixtures, aggregates, fillers, photo-catalytic materials, fibres etc. Based on underlying theory, European building codes, and the construction industry's needs, new types of plasterboard will be developed. The study will also include research, evaluation and application of alternative ingredients and smart components. The present research project concerns the simulation of hardening process of gypsum based plasterboards and materials and influences of fire on the microstructure of these materials. The simulation of hydration behaviour of cement/gypsum plasterboards is executed by extending the CEMHYD3D-model with the hydration of calcium sulphates. In the last ten years the model is extended at the University of Twente for pore water chemistry (Van Eijk, 2001) and slag cement hydration (Chen, 2007).


Fig 1. Scientific Framework of the research

Overall research-objectives

1. The modelling of the hydration.
Calcium sulphates (like gypsum) are in the existing hydration model CEMHYD3D already present, but the way these products are modelled is too limited for the present research.

2. The development of a multi-scale fire model
The fire model which is developed describes the chemical and mechanical changes in the material. The model makes use of the chemical decomposition reactions. Together with the reaction temperatures and an external heat flux this forms the basis for model. The chemical reactions introduce volume changes and changes in the thermal properties (density, specific heat, heat conduction).

3. Computer based design
The combination of the hydration and fire model can be used for the computer-based design of gypsum plasterboards. The design process is cyclic. This will be done by changing the input parameters of the hydration and exposing the 'produced' microstructure to fire with the help of the fire model. The output results of both models can than be assessed according to the predefined requirements. Based on these results the input of the model can be modified and cycle will start again.

4.The development of a forensic fire investigation tool
Forensic research focuses on the determination of the temperature levels (history) and the cause of the fire. The main differences among fires are their speed and attained temperatures. Based on structure changes of the material the temperature and speed of the fire can be determined. For this purpose the fire model will have the possibility to cope with the several fire curves

Current results include;
  • First modification of the hydration model for the use of gypsum as main binder. This modification includes the formation of needles (crystal shape), modification of the primary and secondary nucleation and the including of gypsum as the final product.
  • First version of the fire model has been developed. This model is based on thermo-chemical laws and can predict the influence of fire on the properties of the material (i.e. density, thermal conductivity, specific heat, enthalpy, permeability, specific surface area).
Plans for next years include;
  • Further modification of the hydration model for the use of gypsum, including pore water chemistry
  • Further development of fire model, including improved mass and heat transfer and the introduction of cement phases.
  • Prediction/simulation of the following properties of gypsum plasterboard at ambient and elevated temperature
    • Thermal conductivity
    • Permeability
    • Specific surface area
    • Ultrasoon velocity through the mixtures
  • Simulation of packing of particles.
