Abstract
In order to improve concrete freezing-thawing resisting ability in Inner Mongolia region, adding air entraining agent is one effective measure. Because triterpenoid saponins air-entraining agent have a good applicability for local raw material, it makes concrete slump obvious increase with different water cement ratio, but the range ability first increases then decreases, the 3d, 7d and 28d compressive strength influence are the same to the slump influence, which can effectively improve concrete freezing-thawing resisting cycle times, and mixing with naphthalene series water reducing agent applies to mix small water cement concrete, and high strength grade.
