Abstract

Every year, huge amounts of natural resources are used to produce concrete. Sand and gravel resources are rapidly draining, therefore, it is necessary to reduce consumption. On the other hand, there are a lot of construction waste which can be reused in concrete production. One of possibilities is to use in concrete production ceramic waste. During the research the coarse aggregates were changed to ceramic bricks waste. The changes of fresh concrete workability, density, hardened concrete compression strength, water absorption and frost resistance were evaluated. The results show that ceramic waste has a negative effect to all concrete properties. Ceramic bricks waste should be used to replace coarse aggregate in a lower ratio, such as the possible option of replacing 10 % of coarse aggregates. The stoneware tiles waste show better results (Skominas et al., 2020). This waste can be used replacing up to 60 % concrete coarse aggregates. According to all results can be concluded that stoneware tiles waste is better choice for coarse aggregates production.
