Description:

The paper presents the influence of fine recycled concrete aggregate (RCA) on selected physical and mechanical parameters of cement mortar. RCA was divided into three groups: fine (0/0.25 mm), medium (0.25/1 mm) and the thickest fraction 1/2 mm. The investigations confirmed a significant correlation between the total amount of RCA and the obtained flow for the mixtures and compressive strength. Results showed that the fine RCA should be separated into subgroups as not only total RCA amount but quantity of RCA in each subfraction can have varying influence on mortar properties.
