Concrete containing metakaolin admixture: Freeze-thaw and scaling resistance
Original language description
High concrete durability is one of the factors that can significantly decrease maintenance costs of structures exposed to severe environmental conditions. The mechanical and durability properties of high performance concrete with added metakaolin are studied in this book. Ten percent of the cement in the concrete mixtures was replaced by the metakaolin. In the experimental part of the book, frost resistance and resistance to scaling due to de-icing salts was measured. It was found that the type of addedmetakaolin does not have a significant influence on the results. The frost resistance of both types of concrete with added metakaolin satisfied code requirements and was comparable to the performance of air-entrained concrete. The resistance of concretewith metakaolin against salt-scaling was worse compared to air-entrained concrete. The experimental work proved that the type of the surface treatment for the scaling tests had major influence on the results. This analysis is especially
