Abstract
Utilization of the construction and demolition waste (CD the a mount of water as well as the dosage of plasticizer were adjusted during mixing in order to keep the standard criteria. Next, a positive impact on the properties of hardened concrete was expected due to the effect of micro-fillers in the concrete microstructure . The results of these properties are presented and discussed in the paper, namely density, compressive strength, water absorption capacity and frost resistance. The analysis of the results is focused on the effect of an individual powdered material, on the interaction of the resulting properties of concretes, as well as on the changes of those properties in time, since the data were collected at 7, 28 and 365 days of hardening. Positive effect of fine-grain form of brick, glass and concrete on the compressive strength and partially on the frost resistance was found compared to the reference concrete, while it is not the case of water absorption capacity.
