Why is
the scientific problem of interest at all? . Calcium Aluminate (CA) is an important precursor of cement and is
its fastest-reacting component when the dry cement powder is mixed. ItŐs
hydration upon wetting is therefore a vital step in cement formation. CA is also an important catalyst
substrate whose electronic properties under investigation by other theory

What |
What is the specific
thing that the student will do, and how does it fit inside the overall
project? The project
will involve X-ray diffraction measurements of samples of CA, prepared from a
variety of different sources with different degrees of powder grinding and
compaction. The diffraction
patterns will be measured as a function of time after wetting, since the
changes take several hours to materialize. The resulting changes in lattice parameter and grain
size-strain changes will be logged as a function of the CA formulation. |
