Frost Resistance of Concrete Screed with the Fly Ash Addition

Abstract:

Using of fly ash in concrete screed is becoming a common practice. This situation entails both environmentally and economically positive effect. The problem may occur with the durability and life of such materials. Therefore, it is important to correctly grasp these materials and final properties sufficiently verify. One of these properties is frost resistance. This paper presents the results of measurements on the frost resistance of concrete screed with the substitution fly ash 0-50% by weight of clinker. Specimens were subjected to destructive and non-destructive test of frost resistance after 28 days of ripening and the results were evaluated.
