Abstract
Sub-standard (poor quality) materials have been mentioned as one of the major causes
of building collapse worldwide. The main materials mostly identified as sub-standard
are cement, reinforcement bars, timber and aggregate. This Paper assesses whether
the quality of Type I Portland cement use in Ghana - contribute to the recent building
collapse in Accra and Kumasi. This was achieved through experimental study by
comparing the properties of Ghana cement with that of UK cement. The study found
that the dry density of Ghana Grey cement was higher than both the UK Grey and UK
White cements. Furthermore, the Ghana Grey cement performed better in resistance
to water absorption than UK Grey cement, while the UK White was better than both
Ghana Grey and UK Grey cements. In addition, while UK White cement performed
better in compression than Ghana Grey and UK Grey cements, the Ghana Grey was
better than the UK Grey cement. The results of the experiment clearly reveal that the
