RYUKYU CEMENT

Ryukyu Cement is a company that produces cement. In comparison to typical Portland cement, it is the cement that acquires great strength in a short amount of time. With Portland cement, users can get strength that ordinarily takes three days in just one day. It is used for dam and pier building because of its ability to gently solidify. Internal heat expansion can cause cracks in concrete buildings with a large cross-sectional area, such as dams. It is utilized for marine structures because of its great water tightness and resistance to salt damage (breakwaters). Fly ash is cement made from fine particles extracted from coal ash from a thermal power station and used as a mixing material.
