PURPOSE:To provide a concrete composition having excellent workability due to excellent fluidity and segregation resistance and capable of obtaining a high quality air concrete excellent in freezing and thawing resistance. CONSTITUTION:In the concrete composition containing a segregation reducing agent as a mixing agent, the segregation reducing agent is composed of a cellulose based segregation reducing agent and a acrylic segregation reducing agent. And the segregation reducing agent is preferably composed of 20-40wt.% cellulose based segregation reducing agent and 80-60wt.% acrylic segregation reducing agent. |
