    • Assessing shielding material Performance: Benchmarking of Monte Carlo codes for oil shale and Basalt-Boron fiber concretes Hando Tohver a,* , Andrius Slavickas b , Maryna Holiuk c , Andrejs Krasn¸ i 

      Tohver, Hando; Motlep, Riho; Krasnikovs, Andrejs; Novakova, Iveta; Gulik, Volodymyr; Slavickas, Andrius; Holiuk, Maryna; Vaišnoras, Mindaugas (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-12)
      Cement-based concretes are commonly used for managing radioactive waste due to their low cost and radiation shielding properties. However, the potential of using oil shale ash as an additive in waste packaging material has been overlooked. This study focuses on benchmarking and developing a Monte Carlo based modeling methodology using multiple transport codes (MCNP, SERPENT, SCALE, OpenMC, and ...

    • Bridging Law Application to Fracture of Fiber Concrete Containing Oil Shale Ash 

      Upnere, Sabine; Novakova, Iveta; Jekabsons, Normunds; Krasnikovs, Andrejs; Macanovskis, Arturs (Journal article; Tidsskriftartikkel, 2023-07-23)
      Concrete is a widely used material in various industries, including hazardous waste management. At the same time, its production creates a significant carbon footprint. Therefore, intensive research is being conducted to create more eco-friendly concrete, for example, partially replacing cement with by-products such as oil shale ash (OSA) or improving properties by adding dispersed fibers such as ...
