Abstract.
In this work, experiment on chemical hydration by acid
leaching from a brand of Cement in Nigerian market has been
studied. The physico-chemical characterization of the Sample
by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and
X-ray diffraction (XRD) has been examined. The influence of
acid concentration and system temperature on the dissolution
rates has been investigated. The dissolution rates are
greatly influenced by acid concentration and reaction
temperature. The dissolution investigations gave rise to
activation energy value of 26.3kJ/mol, which affirmed the
diffusion reaction mechanism. Also, about 4.13s-1 and 0.98
were obtained as the system’s Arrhenius constant and
reaction order for the dissolution process, respectively.
Keywords:
ICP-MS, XRD, diffusion reaction mechanism.
