This invention relates to the field of ecological building materials technology, and discloses a biodegradable mold for preparing honeycomb porous concrete. The mold includes a horizontally positioned base plate and four side plates vertically surrounding the perimeter of the base plate. The upper surface of the base plate has several vertically upward-pointing cylindrical protrusions, the tops of which are flush with the tops of the side plates, arranged in a regular hexagonal honeycomb matrix. The mold is made of 100 parts of edible-grade corn starch, 20-40 parts of deionized water, and 2-8 parts of food-grade glycerin. This invention, by combining a starch-based substrate with deionized water and food-grade glycerin, improves the mold's compressive strength and ensures the precision of pore formation. The mold eliminates the need for demolding and degrades in natural soil to generate monosaccharides, providing a carbon source for the early growth of internal plants. The integrated hot-pressing structure of the base plate and protrusions eliminates seams, preventing joint leakage and deformation during vibration compaction and ensuring the interconnected porosity of the porous concrete.
