Description

Technical Field

[0001] The invention relates to the field of aggregate intelligent grading technology, and in particular to an aggregate intelligent grading technology and device for concrete. Background Art

[0002] With the progress of my country's modernization, the concrete industry has developed rapidly. The demand for concrete in the construction industry has continued to increase in quantity and quality. Aggregates, as the raw materials of concrete, have also been in increasing demand. In the process of producing concrete, aggregates are wrapped in cement paste composed of water and cement, and mainly play a skeleton role inside the concrete. Their grading has a direct impact on the properties of concrete after hardening. Aggregate grading refers to the distribution of each particle size of sand and gravel used in concrete. It can be divided into continuous grading and discontinuous grading. Continuous grading is a grading composed of aggregates of continuous particle sizes. Each particle size exists continuously to form a relatively stable stacking structure, while discontinuous grading is a grading based on continuous grading without one or several particle gradings. Aggregate grading is one of the important indicators of aggregates. Different aggregate gradings have a very important impact on the strength, durability, and impermeability of concrete. Aggregates with good grading have a small total surface area and stacking void ratio, which can reduce the amount of slurry and save concrete production costs.

[0003] The early sources of aggregates were mainly natural sand and weathered pebbles. However, natural sand and gravel require the accumulation of natural environment to form, and have the characteristics of long formation cycle and small accumulation, and are non-renewable resources. In addition, during the large-scale mining of natural sand and gravel, it will also cause the riverbed water level to drop and damage the ecological environment. The machine-made aggregate formed by the crushing of rocks by impact crushers has gradually become the main raw material for concrete aggregate. Machine-made aggregates meet the requirements of green, large-scale and intensive construction materials, and have ecological and environmental protection characteristics. They have received more and more attention in recent years. However, in the production process of machine-made aggregates, too much needle-shaped and flaky aggregates added to concrete can easily lead to poor workability of fresh concrete, affecting the construction quality and the mechanical properties and durability of concrete. Therefore, it is necessary to propose an intelligent grading process and device for concrete aggregates. Summary of the invention
