Study of the concept of K-value and efficiency index for fly ash and slag and their assessment and determination for concrete
 Šperling, Petr ; Hela, Rudolf (referee) ; Hubáček, Adam (advisor)
This bachelor thesis deals with the use of active admixtures as a substitute for cement in concrete, specifically power plant fly ash and blast furnace slag. When using power plant fly ash and blast furnace slag as a substitute for cement in concrete, it is necessary to know their effect on concrete and to assess the different properties compared to concrete in which these admixtures are not used. This work will summarize the existing knowledge of the properties of power plant fly ash and blast furnace slag and their effect on fresh and hardened concrete. Furthermore, the possibilities of determining the efficiency index and the so-called k-value concept, which are used to assess the effect on cement mortar and concrete when replacing cement with an active admixture, will be summarized. In the experimental part, emphasis will be placed on determining the k-value. This is described in European technical standards in a very general way and is not sufficiently detailed for specific active ingredients.
