Cement Paste with Recycled Concrete Powder: Long Term Development of the Strength
Original language description
Presented paper deals with using of a recycled concrete powder (RCP) modified by a high speed as microfiller and partial binder replacement in cement pastes. This approach allows to exposed unhydrated cement grains to further hydration. Such use of recycled concrete powder could lead to cost reduction of a concrete mixture. The flexural and compressive strength on samples made of Portland cement containing 0, 33, and 67 wt. % of a recycled concrete powder were determined. Those mechanical properties were determined in several times during 14 months. Results show that 33 wt. % cement replacement seems like limited value, when mechanical properties in long term scale are comparable with a reference sample. Samples with 67 wt. % of RCP had significantly lower strength compared with reference samples.
