Drawings
FIG. 1 is a schematic structural view of the recycled aggregate plant-growing concrete precast block of the present invention.
Description of the drawings: 1-outer frame, 2-inner groove.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.
Example 1
As shown in the attached drawing 1, the precast block of the recycled aggregate plant-growing concrete of the utility model has a regular hexagonal prism structure, and comprises an outer frame 1 and an inner groove 2; the thickness of the outer frame 1 is 5-10 cm, the side length is 30 cm, the height is 12-15 cm, and the height of the concrete block planted in the inner groove is 7-10 cm; the outer frame and the inner groove of the precast block are made of recycled concrete, and the recycled concrete is formed by mixing recycled coarse aggregate and slurry made of cement and water; the concrete height of the outer frame 1 is higher than that of the inner groove 2; the inner groove 2 is filled with a vegetation soil layer.
The recycled coarse aggregate is waste concrete with the particle size of 20-40 mm, and the strength grade is C15-C40. The cement is low-alkali aluminate cement.
