发明名称 PAVING BLOCKS AND METHOD FOR PRODUCTION THEREOF
摘要 PAVING BLOCKS AND METHOD FOR PRODUCTION THEREOF The fracture-free paving block 1 comprises a cement block substrate 1-1 and a top solid layer 1-2 , and is characterized in that the top layer is selected from a cured cement mortar layer and a tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins 2 of 1 to 8 mm wide in horizontal distance 15 from the peripheral edges of the substrate; and the vertical distance 18 from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm. The method for producing the paving block 1 having a tile-like top layer comprises applying adhesive cement mortar between the back of the top layer 1-2 and the upper surface of the substrate 1-1; placing the top layer on the substrate with the above-mentioned margins 2 of the substrate surface; and applying vibration and/or pressurization between the top layer and the substrate.
