Industrial Minerals and Rocks

mineral phases are rich in aluminum making this cement much more durable. This can clearly be seen in sunken port facilities dating from Roman times whose cement survived 2000 years better than many a modern quay made of Port-land cement survived 100 years (Jackson et al. 2013). Perlite is a glass-rich rock that forms by hydration of

EXPLORING CERAMIC RAW MATERIALS IN NIGERIA AND …

Ceramics are classified into two, viz; traditional ceramics and modern (advanced) ceramics. The traditional ceramics, called traditional because they have long been in use, have similar molecular structure to fired earthenware. Members of traditional ceramics include rocks, minerals, clay, concrete, refractories and porcelain.
