Abstract:Presents the results of laboratory studies conducted to determine freezing-and-thawing resistance of anti-washout concretes under water. Three anti-washout admixtures were used in these studies. The water-cement ratio was 0.45, and the sand-coarse aggregate ratio was 0.67. A number of test cylinders were made for testing in compression at 7 and 28 days, and test prisms were cast for determining their resistance to freeze-thaw cycles in accordance with ASTM C 666, Procedure A. The air-void parameters of the hardened concrete were determined on sawn sections. The pore-size distributions of the hardened concrete were measured by a mercury porosimeter. The test results have indicated that the anti-washout concrete having the same water-to-cement ratio and the same air content as the control concrete show poorer resistance to freezing and thawing than the control concrete without the anti-washout admixture.
