Injection apparatus and method for mix concrete that have been undergoing process of mixing and dissipating air and mixing materials on common concrete

摘要

The present invention relates to a high strength concrete having high flowability by mixing 20 to 40% of bubbles with a volume of ordinary concrete and forming a high fluidity concrete. When discharging the mixed concrete formed by injecting a powder mixture material into the high- The present invention relates to a mixed concrete spraying apparatus and method by mixing and dispersing bubbles and powder mixed materials in ordinary concrete which can discharge the air contained in mixed concrete with high pressure air while discharging it.
