Product lineup

■Ordinary Portland cement

A general-purpose cement, ordinary Portland cement is the most common type of cement in the construction industry, comprising 70% of the total used in Japan. It is widely used for concrete and other secondary cement structures in general civil engineering applications and construction work.


■Early-strength Portland cement

Early-strength Portland cement becomes strong in a shorter period than ordinary Portland cement, and is widely used in situations when concrete must harden quickly, such as emergency roadwork and wintertime construction.


■Moderate-heat Portland cement

Moderate-heat Portland cement limits the heat of hydration more than ordinary Portland cement and maintains strength over a long period. It is also highly resistant to chemicals and very durable since it exhibits only a small amount of dry shrinkage. As such, moderate-heat Portland cement is used for large-scale civil engineering structures like dams and bridges, as well as road-surface concrete and mass concrete for foundations of high-rise buildings and other structures.
