Stone for laying

The utility model discloses a sett belonging to the construction material technical field, which solves the problems that the prior sett is in loose binding with a cement layer and is easy to fall off the cement layer. The sett comprises a sett body, wherein the upper surface and the lower surface of the sett body are in transitional coupling with each other through a cant. For assembly, the cement layer is firstly laid on a subgrade, then the lower surfaces of setts press tightly on the cement layer, the setts are laid at due intervals, and clearances between the setts are filled up with part of the cement layer. Due to the existence of the cant, the cement layer in the clearances presses on the cant, thereby having a good reinforcement effect. Thus, the sett is in firm and tight binding with the cement layer and is not easy to fall off the cement layer.
