Embodiment Construction

[0047] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0048] Such as figure 1 Shown, a kind of production technology of ecological concrete comprises the steps:

[0049] Step 1, preparation of ecological cementitious materials: the construction waste clay bricks sorted by the volume method are removed by magnetic separation device and light matter sorting device to remove iron and light matter, and crushed by crushing equipment into blocks with a size of ≤50mm Brick material, after magnetic separation, it is ultra-finely ground by a vertical mill to obtain a specific surface area ≥ 500m 2 / kg of clay brick powder, mixed with a certain proportion of chemical activator in the grinding process, and compounded with slag powder to prepare ecological cementitious materials;

[0050]Step 2, preparation of recycled aggregate: the waste concrete material sorted by the volume method is crushed through prim...

Abstract

The invention discloses a production technology of ecological concrete. The production technology comprises the steps of preparing an ecological cementing material by using construction waste clay bricks, and preparing recycled aggregate by using construction waste concrete; uniformly mixing cement and the ecological cementing material, then adding part of water, natural fine aggregate and recycled fine aggregate, stirring to form slurry, then adding natural coarse aggregate, recycled coarse aggregate, the rest water and a pumping aid, and stirring to prepare C30-C40 strength grade ecological concrete. By adopting the production technology of the ecological concrete, provided by the invention, useful components of construction waste are effectively used, the waste is turned into wealth, resources are saved, and the recycling of the construction waste resources is realized; the prepared ecological concrete is comparative with normal concrete in performance, is low in production cost, and can be largely applied to general construction engineering.

Description

technical field [0001] The invention belongs to the field of building materials and resource recycling, and in particular relates to a production process of ecological concrete. Background technique [0002] With the rapid development of my country's economy and society and the rapid advancement of urbanization, construction and development have produced a large amount of construction waste, whose composition is basically the same, mainly waste sand, waste clay bricks, waste concrete, paper, waste plastics, fabrics, rubber, etc. Light materials and scrap metal, etc. At present, the vast majority of construction waste is disposed of by stacking or landfilling, which not only takes up a lot of valuable land resources, but also causes serious pollution to the environment. A large number of waste clay bricks and waste concrete in construction waste can be used to prepare ecological cementitious materials and recycled aggregates through reasonable processes, which can be used to ...
