Problems solved by technology

[0005] The technical problem to be solved is: the existing collection and distribution of recycled aggregates of construction waste still cannot meet the demand. By further improving the collection and distribution of recycled aggregates, the amount of cement can be further reduced, and at the same time, the utilization scale of recycled aggregates can be increased to meet the needs of the existing road grassroots. strength requirements

Abstract

The invention discloses an inorganic mixture prepared from construction waste recycled aggregate. The inorganic mixture is prepared from the following raw materials in percentage by weight: 93-96 wt% of recycled aggregate and 4-7 wt% of cement. The recycled aggregate with the particle size of 20-31.5 mm is 10%, the recycled aggregate with the particle size of 10-20 mm is 25%, the recycled aggregate with the particle size of 5-10 mm is 30%, and the recycled aggregate with the particle size of 0-5 mm is 35%. By further improving the combination of the recycled aggregate, the cement consumption can be further reduced, the utilization scale of the recycled aggregate is increased, and the strength requirement of the existing road base is met.

Description

technical field [0001] The invention relates to the technical field of recycled inorganic mixtures, in particular to an inorganic mixture made of recycled construction waste aggregates and a preparation method thereof. Background technique [0002] At present, the construction waste in Beijing is mainly the demolition of the shed renovation project. The construction waste generated by the shed renovation project is often disposed of by open-air stacking, underground burial, and incineration, which seriously pollutes water, air and soil, and seriously pollutes the environment. Effective treatment of construction waste can not only avoid polluting soil, water and harmful gases, but also save landfill space. [0003] The rapid development of my country's highway construction consumes a large amount of natural aggregates, which are difficult to regenerate in the short term. Sorting concrete blocks, bricks, mortar blocks, etc. from the construction waste generated by the demolit...
