Product Information


A cement made by mixing ordinary Portland cement with fly-ash in compliance with the Japanese "JIS A 6201 fly-ash for concrete" standard, offering concrete fluidity equivalent to that of ordinary Portland cement but with less mixing water by comparison, thus reducing hydration heat as well.


  1. Offers far superior long-term strength in material age after three months.
  2. Since less hydration heat is generated, it is best suited for pouring massive quantities of concrete.
  3. As it generates chemically stable hydrated substances, it exhibits superior resistance to acids and salts.
  4. Affords high watertightness, demonstrating effective waterproofing.
  5. Its low dry shrinkage reduces the occurrence of cracks.
