HIGH SPEED HARDENING COMPOUND USING FOR MENDING CONCRETE STRUCTURE AND THIN STRATUM MENDING METHOD USING THE COMPOUND

摘要

A rapid hardening mixture used at repair of concrete structure is provided to reduce a defect generation rate and to minimize change of quality. A rapid hardening mixture is manufactured by mixing 5~20 parts by weight of combined water and 50~120 parts by weight of coares aggregate based on 100 parts by weight of pre-mix type rapid hardening fission material in order to reveal compressive strength more than 20.0 MPa within 2 hours after filling.
