Karb Stone Mold

Kerb stone mould is the high quality mould. It is made with best quality plastics. The finishing of the mould is very good. Because of its good finishing, the kerb stone produced by it are of high quality.A concrete paver is defined as having a maximum aspect ratio of 4:1, and a minimum thickness of 2 3/8'' (60mm). Concrete pavers are generally able to be lifted with one hand. Concrete slabs, on the other hand, will have an aspect ratio greater than 4:1 and a minimum thickness of 2'' (50mm).A concrete mix of 1:2:4 (cement: sand: stone chips) by volume may be used for cement concrete paving blocks with water to cement ratio of 0.62. The concrete mix should not be richer than 1:6 by volume of cement to combined aggregates before mixing.Compressive strength Average not less than 450 Kg/cm2 3.
