The aim of this study was to determine the effect of different amounts of filler on concrete properties. An experimental approach has made it possible to develop a construction product made from limestone dust, which is considered waste. This paper presents an experimental study on the prospects of using a mixture of waste limestone powder for the manufacture of an economical and lightweight composite as a building material. This paper also presents the results of research on the possibility of using limestone dust as an aggregate in the production of concrete with lightweight aggregates. In this way, different amounts of limestone dust were used. Tests were conducted on concrete to replace 30, 50, and 70% by weight of coarse aggregate. The mechanical properties of concrete mixtures with high proportions of limestone dust were examined. The achieved compressive strength, flexural strength, and unit weight correspond to current international standards.
