Hydraulic material composition
A hydraulic material composition comprising cement and 0.01 to 2.0% by weight, as zinc oxide based on the cement, of a zinc-containing compound, such as zinc oxide having an average particle diameter of at least 20 micrometers. It does not corrode a steel material even when molded with the use of sa...

| Zusammenfassung: | A hydraulic material composition comprising cement and 0.01 to 2.0% by weight, as zinc oxide based on the cement, of a zinc-containing compound, such as zinc oxide having an average particle diameter of at least 20 micrometers. It does not corrode a steel material even when molded with the use of sand or sea water containing steel-corroding components such as chlorides. |
