Concrete taking waste glass as aggregate and preparation process thereof

Abstract

The concrete taking the waste glass as the coarse aggregate obtained by the technical scheme can meet the index requirements on the concrete in the prior art, and by detecting the mechanical properties, chloride ion permeability resistance and scanning electron microscopes of the concrete according to different mixing amounts of glass, the test piece strength is 1.12 times of that of common concrete at most when the mixing amount is 63%; the chloride ion diffusion resistance is also enhanced, and the durability of the concrete is greatly improved. Besides, natural sand resources can be effectively saved through practical popularization of the technical scheme, the pressure of lacking of the natural sand can be greatly relieved by using the glass sand, construction waste is recycled, technical and economic policies related to resource saving and environment protection in China are implemented, and the glass sand is low-carbon and environment-friendly and has great significance and development prospects. In addition, the industrial cost can be further reduced, the cost of concrete per cubic meter is reduced, and huge economic benefits are brought to enterprises.

Description

Technical field [0001] The present disclosure specifically discloses a kind of concrete with waste glass as the aggregate and the preparation process thereof. Background [0002] With the continuous acceleration of China's urbanization process, the resulting construction waste problem has attracted more and more attention. Waste glass is an important part of construction waste, because waste glass is a non-biodegradable material, how to effectively recycle them has become an urgent problem to be solved. China produces about 3.2 million tons of waste glass every year, accounting for 2% of the total amount of urban living garbage, which brings a heavy burden to the human living environment, and discards a large number of waste glass, which not only occupies space, but also pollutes the environment, and also causes a lot of waste of resources and energy. [0003] In the glass manufacturing process, the reuse of waste glass can reduce production energy consumption, water reduction ra...

AI Technical Summary

Problems solved by technology

About 3.2 million tons of waste glass are produced in my country every year, accounting for 2% of the total urban domestic waste, which brings a heavy burden to the living environment of human beings. A large amount of waste glass is discarded, which not only takes up space, but also pollutes the environment and causes Huge waste of resources and energy

[0003] In the glass manufacturing process, the reuse of waste glass can reduce production energy consumption and water raw material energy consumption. However, due to the complex composition of waste glass, it is required to remove impurities and color separation of waste glass before reuse. Therefore, waste glass The application in the production of new glass is extremely limited, so it is necessary to study the use of waste glass in areas with high demand and more relaxed requirements for its composition
