CSA-based Ultra Rapid Hardening Cement Mixed Powder, Material for Repairing a Road and Method of Road Repair Using the Cement |
| abstract |
The present invention relates to a new super-fast cement mixture powder composition that secures economic feasibility and secures physical performance by using relatively inexpensive calcium sulfoferrite (CSF) instead of expensive calcium sulfoaluminate (CSA), and a preferred method of using the same will be. The super-velocity cement mixed powder composition according to the present invention contains 15 to 50% by weight of cement, 10 to 20% by weight of calcium sulfo ferrite (CSF), 10 to 20% by weight of anhydrite, and 5 to 20% by weight of fine powder of blast furnace slag. %, a binder composed of 15 to 30% by weight of fly ash in a combined heat and power plant; The length is 10mm or less, and 0.05 to 0.5% by weight of glass fiber compared to the binder; 0.05 to 1.5% by weight of the retarder compared to the binder; 0.01 to 1.5% by weight of the accelerator relative to the binder; It is characterized in that it comprises a fluidizing agent in an amount of 0.2 to 1.5% by weight compared to the binder. |
