Evaluation for Antifreeze of Concrete Based on Method of Bubble Parameters

Article Preview

Nowadays we usually use air bubble parameter to evaluate the freeing resistance. This method save time, water and electricity. However, this method is too simple to reduce the accuracy and limit its application. For changing this fact we stood the minimum observation Wire length and standard maintenance age influence on air Bubble parameters. Firstly According to air bladder spacing coefficient of the different traverse wire length, calculate the range and deviation coefficient. Secendly detect the antifreeze degree by rapid freeze-thawing test, finaly set up the regression equation among the air spacing coefficient of 3d,28d and 90d. In conclusion, wire length should take at least 2 times of the now minmum. We cannot directly use the spacing coefficient of bubble in 3d to evaluate the freezing resistance of the concrete structure. But we can use equation y = 0.356x +0.514 to convert that of 90d to 28d and evaluate the freezing resistance of the concrete structure.
