Example Embodiment

[0011] A method for recycling construction waste, comprising the following steps:

[0012] (1). Sort out wood blocks, waste plastics, waste paper, steel bars, etc. in red brick construction waste or waste concrete construction waste, and implement classified management, storage, and centralized sales;

[0013] (2). After the abandoned red brick construction waste or waste concrete construction waste is transported from the demolition site to the factory area, it is initially crushed by the jaw crusher, and the coarse construction waste generated is transported by the belt to the hammer crusher for further crushing. The red brick recycled aggregate and the concrete recycled aggregate with a certain particle size were obtained respectively;

[0014] (3). The crushed red brick recycled aggregates and concrete recycled aggregates are then screened by rolling screens respectively, and three different particle size grades of 5-40 mm, 0.16-5 mm and 0-0.16 mm are screened out. The...

Abstract

The invention discloses a construction waste recycling treatment method. According to the method, construction wastes are crushed and screened to make a regenerated aggregate, and the regenerated aggregate is further mixed with cement, sand and water to obtain mortar. In preparation, exploitation of natural resources is reduced, city construction wastes can be subjected to harmless and resourcefultreatment, the burden of garbage to cities can be alleviated, the problem of resource utilization of construction wastes, industrial wastes and living garbage is solved, and effects of turning wasteinto wealth and protecting the environment are achieved.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a method for recycling construction waste. Background technique [0002] With the continuous acceleration of urbanization, the amount of construction waste generated and discharged in cities is also increasing rapidly. While enjoying urban civilization, people are also suffering from the troubles caused by urban construction waste: the pace of implementation of projects such as urban village renovation, demolition and temporary demolition, and old city renovation is accelerating. As cities become more and more beautiful, the amount of construction waste generated But it is increasing day by day, becoming another major difficulty in environmental protection. Construction waste is mainly composed of inorganic substances such as broken concrete, broken bricks, broken sand and gravel, and its chemical components are silicates, oxides, hydroxides, carbonates, sul...
