Summary:
The present Thesis has been accomplished through the Undergraduate Program of “Geology and Geoenvironment”. The aim of the thesis is to examine the existence of silica sand, at Skala region in Kefalonia Island and to figure out its suitability level for construction uses. The material had been also extracted during the past, around 1980, by TITAN SA and AGET Hercules SA cement companies.
According to TITAN SA, 6.000 tons of silica sand was extracted every year from Skala region in Kefallinia Island. This amount of sand was concentrated at the cement factory of the company at Rio, in Peloponnese region, until 1985. Since then the place has been almost abandoned, with terraces that cover the old extracted area. Two main quarries have remained untouched so that we have a picture of how the place used to look like.
At the current study, quantities of Pleistocene silica sand were collected from the wider area of Skala and specifically from past sand-quarries and from areas which are located regional of these old extraction sites. The analysis of the samples has been done at the National and Kapodistrian University of Athens and at the Technical University of Athens. The purity of the samples in silica content has been examined through the mineralogical analysis of the samples, the determination of the carbonate free fraction and other impurities that influence the quality of the sand, regarding the uses in the construction industry. To figure out the SiO₂ and CaCO₃ content, as well as the clay mineral content and impurities, X-Ray Diffraction, Stereoscope and Sieve Analysis were carried out.
