Mechanical pavement brick and preparation method thereof
The invention discloses a mechanical pavement brick which comprises a surface material layer and a bottom material layer, wherein the bottom materials of the bottom material layer consist of the following components in parts by weight: 200 parts of 42.5# cement, 100 parts of 0.5cm pebbles or ores, 850 parts of 200-mesh crushed pebble powder, 850 parts of 200-mesh crushed ore powder and 110 parts of water. The surface material of the surface material layer contains talcum powder with the granularity of over 300 meshes, and the talcum powder accounts for 15wt% of the surface material of the surface material layer. Compared with the prior art, the mechanical pavement brick disclosed by the invention has the advantages that the surface layer is fine and smooth, and small gaps among the particles are avoided.
