Development of mix design for heavy concrete weights
 Jobánek, Jaromír ; Puttner, Jan (referee) ; Hela, Rudolf (advisor)
Bachelor thesis focuses on the development of fine-grained concretes for the production of heavy weights, particulary for fishing purposes. Thesis describes the behavior of concrete and components and proves the danger of lead products.

Design of Heavyweigth Concrete Used in Radiation Protection by Nuclear Elemental Analytical Techniques
 Podhorská, Janette ; T., Palou, Martin
High compressive strength heavyweight concrete specimens were prepared using two types of high-density aggregates, Portland cement, and SCMs. Elemental composition of aggregates and cementitious materials were performed by NAA, PGAA, and XRF methods. The mechanical and physical properties confirm that these concretes meet the requirements of concrete strength grade C55/67 after 28 days of curing, which makes them considered High Compressive Strength Concretes. The fresh and dry density values far exceed 3,000 kg m-3. Other properties, tensile strength and modulus of elasticity provide basic evidence to support the idea that these concretes could be considered as High-Performance Heavyweight concretes. Also, the ingredients of the above concrete showed good activation properties.
