This paper presents a detailed investigation in to the air enterainment and frost resistance of high fluidity concrete mixes incorporate various types of fine mineral powders and viscosity agents. The laboratory made concrete test specimens taken from SOliters pan mixer and ready mix made concrete test specimens taken from different locations of the full scale model wall were examined for air void system determination and freeze-thaw durability.lt was found that the air content of high fuluidity concrete mixes made in the laboratory differ from air content of harden concrete (i. e. loss of air),but the air void stability probrem was not seen in the test specimens taken from different locations of the full model mold. The effect of curing method on the frost resistance of both AE and non AE mixes was found to be very significant.
