Opis:
In the architecture of Krakow we can find many stones which were quarried mostly from de-posits situated not far from the town. They gave a unique image of present, visible elements in the architecture. Many artists used a marble as the building and decorative stone, in sculptures and sepulchral art. Since XIVth century one of the most popular types of stone, which have been applied in the architecture of Krakow, is the Dębnik “marble”. After polishing, it has a deep black colour and, together with Paczółtowice “marble” has been given the fantastic complement of decorative elements in the monu-ments. In the Krakow we can find a lot of places where both “marbles” have been applied as a decorative elements in the architecture. These stones were forming the cultural heritage of Cracow. Usually they are used in sacred architecture. Dębnik and Paczółtowice “marbles” have been applied in many places, for example at the St Mary's Church and at the Wawel Cathedral, as well at Collegium Maius, St Adalbert’s Church in Market Square or at St Peter and Paul’ Church.

Opis:
The self-compacting concretes (SCC’s) are characterized by their high fluidity so that they could be placed without any vibration. The effect of fillers addition on the behavior of SCC in fresh and hardened state is of great importance. This incorporation of marble powder aims to preserve the environment and to widen its use in the future in SCC formulation. The present research experimental program examines the effect of the partial substitution of cement with marble powder on the characteristics of self-compacting concrete in fresh and hardened state. Thus, the marble powder (MP) was introduced into the composition of self-compacting concretes at dosages of 10%, 20% and 30%. Three water cement ratios (W/C) of 0.4, 0.5 and 0.6 were maintained for the studied mixtures. The reference one with 100% of cement served as a control concrete mix. Finally, it can be concluded that such valuation of the marble waste could be beneficial for self-compacted concrete formulation.
