| titleOfInvention | A kind of application of ultra high early strength poly-carboxylic water reducer in Prestressed concrete cylinder pipe |
| abstract | The invention discloses a kind of preparation method of Prestressed concrete cylinder pipe, including：Ring orientation prestress steel wire is wound on the outside of the concrete tube core with steel cylinder, then spray cement mortar protective course, that is, Prestressed concrete cylinder pipe is made；The concrete tube core by body at the beginning of the concrete formed after concreting tube core by carrying out natural curing to be formed；Wherein, the concrete includes cement, gathered materials, water and ultra high early strength poly-carboxylic water reducer, and the ultra high early strength poly-carboxylic water reducer is formula (1) or the compound shown in formula (2)；The invention also discloses Prestressed concrete cylinder pipe made from the preparation method as Prestressed concrete cylinder pipe.The Prestressed concrete cylinder pipe preparation method of the present invention can realize the steam curing conservation of exempting from of Prestressed concrete cylinder pipe, can also improve the intensity of Prestressed concrete cylinder pipe, while have the advantages of simple to operate, production safety, cost are cheap, energy-conserving and environment-protective. |
