Mechanical activation of recycled concrete as an active ingredient
Opat, Lubomír ; Hela,, Vlastimil (referee) ; Hela, Rudolf (advisor)
This diploma thesis deals with the issue of using fine powder of concrete recyclate. In this thesis, the theoretical expectations of milling are summarized as well as high energy milling. Afterwards professional articles, in which fine powder of concrete recyclate is successfully activated, are described and commented on. In the experimental part, there are 11 recipes of cement mortar and 3 recipes of concrete mixed. The benefit of using fine powder of concrete recyclate as a possible substitute for part of the cement is evaluated.

Circular economics in construction
Tatarin, Tomáš ; Marek, Martin (referee) ; Krejza, Zdeněk (advisor)
The goal of this bachelor thesis Circular Economy in Construction is to map the sources of primary raw materials and the production of recyclates in the context of construction production and to perform a price and geographical analysis. The extension of the principles of circular economy is set in the context of the now widespread linear economy. The bachelor thesis is divided into two parts. The theoretical part deals with the analysis of the circular economy and the possibilities of recycling construction waste. The practical part then analyses the current state of production of minerals key to the construction industry, the current production of construction recyclates, the possibilities of increasing recycling and increasing the applicability of the essence of the circular economy. The paper concludes with a summary of the results of the analysis and possible improvements.
