About 200 concrete block specialists from Europe, Russia and the Middle East visited the demonstration of a complete refinement line for concrete and concrete caststone blocks on the 4 days of the exhibition. From 14 to 17 September 2011, SR Schindler demonstrated the different post-treatment processes on the dry side twice daily with a fully automatically working plant. Raw products were bush hammered/ aged, curled and coated so that the visitors were subsequently able to directly compare the different surfaces with one another.
