Sažetak
This paper examines the possibility of using crushed brick and recycled concrete as a partial replacement of natural aggregates in a production of prefabricated wall panels used for constructing nearly zero energy buildings (nZEB).Replacement ratios of natural aggregates by 40%, 50% and 60% were investigated. Mechanical, durability and thermal properties of recycled aggregate concrete were tested. The test results indicate the possibility to manufacture concrete with recycled concrete aggregates and recycled brick aggregates which can find their wide use in building construction process. In addition, energy efficiency and sustainability parameters of recycled aggregate concrete can be coupled with an exigent need to improve energy performance of the building stock in the EU and neighbouring countries. It is shown in this paper that one can save around 46% of embodied energy and around 39% of embodied carbon per panel for a life span of 50 years, compared to the conventional structural concrete insulated panels (SCIP’s).
