Abstract

The aim of the research was to determine the possibility of using the fine fraction from the recycled concrete to produce the cement composites. The research was based on a rotal plan with two variables: x1 (the amount of the recycled addition, 0-40% c. m.) and x2 (the amount of the superplasticizer, 0-1% c. m.). The recycled material was ground to 0.125 mm and roasted at 700°C. The statistical analysis of the findings led to the conclusion that the recycled fine fraction can be added to the cement composites (up to 20% of the cement mass) without a significant decline in their parameters’ values.
