Abstract
The invention discloses an on-site recycle method of construction wastes. According to the on-site recycle method, construction wastes are classified into four types: woods, metals, cloths and bricks, wherein the four types of the construction wastes are respectively stacked. To the construction wastes in the type of the brick, Breaking and sieving processes are carried out on a construction site to obtain medium sand, crude sand, graded broken stone in 5-20mm and graded broken stone in 20-40mm, wherein the medium sand is used for mortar plastering and material blending, the crude sand is used for blending concrete used for pouring a pillar, and the graded broken stone in different grades are used for mixing materials in a cushion layer of a terrace or a concrete pillar. The graded broken stone and the crude sand are blended according to a ratio to prepare raw materials of cement bricks or a cement-stabilizing broken stone layer of a construction road. The woods, the metals and the cloths, which cannot be processed on-site, are sent to a related recycle station or processing field for recycle after being processed. In the invention, by means of recycle of the brick wastes after the breaking and sieving processes on a construction site, not only is a building cost saved but also a transportation cost of the building cost is reduced. The on-site recycle method can reduce a discharge amount of the construction wastes and reduce influence of the construction wastes on environment.
