Regeneration method of activated micro powder from construction waste and product of activated micro powder

Abstract

The invention discloses a regeneration method of activated micro powder from construction waste and a product of the activated micro powder. The method comprises the following steps: 1) sorting out red bricks in the construction waste by a sorting machine; 2) crushing the red bricks by a crushing and screening system, so as to obtain a material with the particle size smaller than 30mm; 3) sending the material to a red brick storage bin for storage; 4) when a material storage amount meets the working requirement of a mill, transporting objects to the mill by an unloading system, performing grinding production to regenerate the activated superfine powder. The method provided by the invention is simple in process and easy to realize, and the construction waste is sorted by ingeniously adopting the sorting machine, and the sorted red bricks are subjected to crushing, screening and grinding processes in sequence to regenerate the activated superfine powder with large specific surface area and high activity, and the method can effectively solve the problem of difficulty in recycling the construction waste, achieves the aims of environment protection and resource recycling, realizes environment protection and great cost reduction, is easy in construction, has good economic benefit and social benefit, and is beneficial to being widely popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of construction waste regeneration active micropowder, and in particular relates to a method for construction waste regeneration active micropowder. Background technique [0002] The rapid growth of population and the development of urbanization have led to the rapid development of the construction industry in central cities. Every day, old buildings are torn down and demolished, resulting in more and more construction waste (among them, waste concrete accounts for 34%). Construction waste refers to Wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction and construction units or individuals. The components of construction waste include: scattered mortar and concrete, broken bricks and broken concrete blocks, yellow sand, gravel, block stones, and muck scattered during transportation. At the same time, in order to meet th...

Problems solved by technology

Landfilling of construction waste not only wastes resources, pollutes the environment, and destroys ecology, but also takes up a lot of land.

[0003] At present, the current resource utilization of construction waste is very single. The waste concrete can be made into recycled aggregates for the production of recycled concrete, recycled mortar, recycled wall materials, etc., while the waste bricks in construction waste have many pores and large water absorption. , not suitable for the preparation of recycled aggregates and cannot be used
