Abstract

Research is described that was aimed at developing a test method which can be reasonably and rapidly performed in the laboratory and in the field to predict, with a high degree of certainty, the behavior of concrete subjected to the action of alternate freezing and thawing. The conductometric evaluation of concrete durability was explored with 3 different test methods: conductometric evaluation of the resistance of concrete to rapid freezing and thawing; conductomtric evaluation of the resistance of concrete to natural freezing and thawing, and conductometric evaluation of the pore size distribution of concrete and its correlation to concrete durability. The study showed that conductance could be used as a viable method for determining the durability of portland cement concrete. This would also allow the continuous monitoring of concrete durability without the removal twice per week from the freeze/thaw chamber. Recommendations for the continued development of these test methods are also included.
