 note = {application/pdf, This investigation was undertaken to develop data on the early frost resistance of high flowing concrete made either with various type of mineral fine powders or viscosity agents. From the results of this investigation it was found that the test cylinders cast from air entrained concrete (ie., air>3.5%)which cured up to 23°D.D prior to freezing, performed with satisfactory resistance to early freezing and thawing cycles. However the 28 days strength ratio of all AE specimens were above 100%. This study recommends early continuous protection until AE high flowing concrete has attained compressive strength of 70 to 80 kg/cm^2.},
