Problems solved by technology

At the same time, precisely because of the needs of environmental protection, the mining of natural sand and gravel will be subject to more and more restrictions, which will lead to an increasingly tight supply of sand and gravel
[0003] In addition, as a kind of industrial waste, fly ash not only pollutes the environment, but also takes up a lot of fertile land for stacking and disposal.

Abstract

The invention is ecological concrete mixture used for bearing structure of civil engineering and prodn. method. It is produced by stirring main raw material regenerated crude aggregate created by grinding discarded concrete, cement, flyash and water.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an ecological concrete material for load-bearing structures and a preparation method thereof, which mainly use regenerated coarse aggregate obtained by crushing waste concrete and industrial waste fly ash as main raw materials. Background technique [0002] Due to many reasons such as municipal relocation, road expansion, accident demolition and renovation and reinforcement, a large amount of waste concrete has been generated. These waste concrete have seriously affected the improvement and sustainable development of urban ecology and environment. At the same time, precisely because of the needs of environmental protection, the mining of natural sand and gravel will be subject to more and more restrictions, which will lead to an increasingly tight supply of sand and gravel. [0003] In addition, as a kind of industrial waste, fly ash not only pollutes the ...
