摘要

u The paving-stone or plaster plate is made from concrete with smooth or formed surface, with or without the provision of measuring rods or teeth. The teeth have recesses, which interlink next to each other. Two colors flow on the plaster surface, having differently dyed concrete pastes. Large concrete aggregates (3, 4, 5) are provided next to each other with different color cement paste (6, 7), with small concrete aggregates such as sand mixed. The cement paste is treated by water jet, milling, sanding or other mechanical surface treatment.
