PURPOSE: A lawn block is provided to improve durability by combining bottom ashes weak for shock by a bonding agent containing polymers, to assemble the lawn blocks at any directions, and to widen a lawn area. CONSTITUTION: A lawn block is composed of a lawn planting space part(3) and porous bottom ashes with good repairability and air-permeability. A bonding agent containing polymers is used to increase durability of the bottom ashes. The polymer, bonding agent, and bottom ashes are in the mixture ratio of 1¯2wt%:10¯20wt%:78¯89wt%. Cement is used for the bonding agent. The well-shaped lawn block comprises a horizontal unit(1) and a vertical unit(2) crossing each other and the lawn planting space part formed in the center. The space part is opened in the four directions to connect the blocks to each other.
