As a part of the Polish National Architectural Workshops in Kielce organized on the initiative of students and with the use of Kielce SARP in the period between 21 and 24.05. 2015 we had the pleasure to accompany the participants during a tour around the most interesting newly built facilities near Kielce. These included Science Centre Leonardo da Vinci, and being in the final stages of construction facility, the European Centre for Geology, University of Warsaw. The investments are located in the vicinity of Chęciny near Kielce. For both projects the company, Dyckerhoff Poland, provided concrete mixtures - were standard and special concrete, and more precisely the architectural coloured concrete mixtures.

One of the interesting items of the Science Centre Leonardo da Vinci is so called, "the geological wall’’ (photo) made of architectural coloured concrete. Thanks to the invitation of Mr. Jakub Heciak of SARP we could present interesting facts and scenes of its formation.
