The CEMHYD3D component of the VCCTL needs to continue to be developed during the lifetime of the consortium and beyond. This development must take a two-fold path: improving the basic chemical and physical science, including kinetics, of how portland cement hydration is treated under different environmental conditions (temperature, moisture, etc.) and incorporating and/or improving the reactions and interactions of materials like slag, fly ash, metakaolin, and limestone. This will make the model more and more useful for a wider range of materials and hydration conditions. Computational improvements in the model, like improving run time or altering the hydration model to allow the user to increase the model resolution by decreasing the physical dimensions of each voxel, are always being considered, since the computations and the materials science go together to make possible improvements in computational materials science.
