Description

Concrete aggregate conveying system

Technical Field

The application relates to the technical field of concrete aggregate conveying, in particular to a concrete aggregate conveying system.

Background

Aggregates, also known as "aggregates", are granular materials that act as a framework and fill in concrete and mortar. The aggregate comprises fine aggregate and coarse aggregate, wherein the aggregate with the particle size of less than 4.75 mm is called fine aggregate and is commonly called sand; aggregates with a particle size of more than 4.75 mm are called coarse aggregates, commonly called stones. The aggregate is used as a main raw material in concrete and plays a role in skeleton and support in buildings. When the aggregate is mixed, the cement is stirred by water to be thin paste, if the aggregate is not added, the cement cannot be molded, and cannot be used, so that the aggregate is an important raw material in construction.

In recent years, the world building industry has entered a high-speed development stage. The occupation of natural resources and the negative impact on the environment caused by concrete as the largest man-made material also lead to the discussion of sustainable development problems. The amount of waste concrete removed annually in the world, waste concrete from new buildings, and waste concrete discharged from concrete plants, prefabrication plants, etc. is enormous. The development and application of the recycled concrete aggregate solve the problems of difficult treatment of a large amount of waste concrete and the gradual deterioration of ecological environment caused by the difficult treatment of the waste concrete on one hand; on the other hand, the construction waste recycled aggregate is used for replacing the natural aggregate, so that the consumption of the natural aggregate in the construction industry can be reduced, the exploitation of natural gravels is reduced, the problem that the natural aggregate is increasingly deficient and the ecological environment is damaged by the exploitation of a large amount of gravels is fundamentally solved, the living environment of human is protected, and the requirement of sustainable development is met. The recycled concrete aggregate is new concrete prepared by crushing and grading waste concrete blocks, mixing the crushed and graded concrete blocks with a certain proportion, partially or completely replacing natural aggregates such as sand stones and the like, and adding cement, water and the like.

In view of the above-mentioned related technologies, the inventor believes that the concrete will carry a lot of powder or fine sand after being crushed, and if the aggregate is directly used to make the concrete, the water demand of the concrete is large, the plasticity retention is poor, the shrinkage is increased, the strength of the concrete is reduced, and the structure is easy to crack.
