Durability of Concrete with Fly Ash from the Dam Orlík after 55 Years

Abstract:

The paper focuses on some properties of concrete with fly ash after 55 years in operation. Among other things this topic refers to still current issue of sustainable development. In this case, it is saving of cement by using of substitution of fly ash. Another researched topic in the paper is the durability of structures and building materials. For obtaining important data, samples of concrete were extracted from the body of the dam Orlík, which has been in operation since 1961 and fly ash was used in a mixture. The results of the measurement of carbonation and frost resistance of concrete with fly ash addition are presented and analyzed in this paper.
