Abstract
Environmental and health considerations have led to the substitution of cellulosic
fibres for asbestos fibres in many cement-based products. Inevitably, the
substitution has required modifications to the manufacturing process.
Certain production techniques associated with the switch to cellulosic fibres and
other additives needed elucidation. It is possible that to ensure the required
concentration of certalr additives in the final product, an excess is being used in
the process because of uncertainties about the quantitative balance of the process.
My intention was to examine the potential tole for Fourier Transform Infrared (FTtR)
Spectroscopy in the investigation of the materials constituting fibre-reinforced
cement boards.
I was able to show that qualitative and quantitative determination of certain of the
components in the final product are possible with adequate precision and
reproducibility to be of value to the manufacturer, I also showed that care taken
in the preparation of standard and analytical samples was essential for the success
of such analyses.
