SOKA is committed to sustainable development and protecting natural resources.
SOKA markets the materials resulting from extraction and, therefore, diversifies the range of products available for you.
SOKA's extra-siliceous, high-purity, natural sands (95% mini SiO2) are light grey in colour and are obtained after various washing and screening operations (no crushing). A range of grain sizes, 0/1mm, 0/2mm, 0/4mm, 0.6/1.6mm and 2/6mm can be used for many industrial applications:
Our raw kaolins and our AK S3 kaolinitic clay are rich in alumina and are used to make white cements.
