The paper presents the results of research of selected properties of high-strength concrete modified with a filler derived from the recycling of shredded ceramic flowerpots. The concrete features such as: air content in the concrete mix, consistency of the concrete mix, compressive strength and frost resistance were evaluated. Frost resistance tests were carried out by two methods: the first direct method for 150 cycles of freezing and thawing and the second by determining the structure characteristics of concrete porosity using automatic image analysis. Damaged ceramic flowerpots were subjected to a mechanical treatment consisting on grinding them in a mill and then in a disintegrator. Powdered ceramic waste was added in amounts: 10, 20 and 30% of cement mass as a filler, simultaneously the same amount of mineral aggregate was reduced. In concretes made with the addition of shredded waste ceramics, mechanical features have been improved, which leaded to achieving higher average compressive strength compared to the reference concrete without this additive. Concretes with the addition of ceramics was also characterized with greater frost resistance. Frost resistance tests carried out with the help of automatic analysis of pore distribution in concrete proved to be an effective tool for assessing concrete resistance to cyclic freezing and thawing.
