CONCRETE PRODUCTS & CAST STONEwww.cpi-worldwide.com CPI %u2013 Concrete Plant International %u2013 6 | 2025dimensions. At the same time, tools were developed that enabled increasingly differentiated products: functional spacers, drainage functions, colour mix surfaces and interlocking contours even on the underside of the stone. Molds with contoured draw plates or draw fingers for the internal profiling of concrete products are as commonplace in use today as tamper heads with heated tamper shoes and mechanically or pneumatically moved tamper heads for particularly special product surfaces.In addition, surface treatments such as washing, blasting, grinding, bush-hammering or curling have considerably expanded the design possibilities in concrete block plants. As a result, concrete paving block became a product that was not only functional, but also aesthetically and ecologically convincing. Surfaces paved with paving stones have been part of everyday life around the world for many decades, although they are rarely consciously recognised.The mold became the decisive quality factor. Over the past 3 decades, service life has increased from around 35,000 to over 100,000 cycles %u2013 progress that reduces downtime and cuts costs. A rethink has also long since begun when it comes to materials: Alternative binding agents are increasingly replacing cement in order to reduce CO2 emissions and increase performance. Old concrete products have long been recycled to save valuable raw materials.Each of these developments shows: Concrete paving block production and mold making are a joint system. Machines, materials and tools influence each other %u2013 and every advance benefits both sides. Kobra as a development partnerKobra Formen GmbH has established itself as a driving force in this interplay.
