FPC method
A method for suppressing explosive spalling by mixing a small amount of polypropylene resin powder, which has a relatively low melting point, into high-strength concrete to improve the fire resistance of reinforced concrete members. 【Features】 - Achieves 3 hours of fire resistance with a small amount of polypropylene resin powder. - The concrete itself has properties that suppress peeling and spalling, eliminating the need for fireproof coating, and costs less than 1/10 of that required for fireproof coating. - Has strength and durability equivalent to that of normal high-strength concrete. - No special equipment is required during concrete production. - Minimal changes in the properties of fresh concrete. ● For other functions and details, please contact us.
