The paper presents the possibility of using recycled aggregate from precast concrete paving elements
and kerbs in the production of concrete kerb units. Experimental work included several types of concrete consistency
class S1, made with different amounts of cement and coarse recycled concrete aggregate. The influence of percentage
and grain size of recycled concrete aggregate on concrete compressive strength at different ages was observed. Based
on the experimental results, it can be concluded that the use of recycled concrete as an aggregate creates a new
composite material that can be used for the production of precast elements. The results show that the replacement of the
coarse natural aggregate with aggregate from crushed concrete is possible to produce concrete curbs that meet the
requirements of EN 1340, but the class depends on the replacement percentage of the natural aggregate with recycled
ones. In this way, the production waste is turned back to process, and the ne...wly created concrete is certainly ecological
material.
