Description

Technical Field

[0001] The invention relates to the technical field of concrete raw material processing, in particular to a concrete raw material screening device. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and additives added when necessary in a certain proportion, and is evenly mixed, compacted into a dense shape, and cured and hardened. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its use range very wide. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. Cement is one of the most important raw materials in concrete. It is a powdery substance, mainly made of limestone, clay and other materials through high-temperature calcination. After mixing aggregate, sand and water, cement can be hardened into a very high-strength building material. Aggregate is one of the raw materials that occupies the largest proportion in concrete. It is composed of stones such as crushed stone and pebbles. The size of aggregate The minimum should be between 5mm and 20mm. Aggregates of different sizes can be selected according to the purpose of concrete to ensure the strength and stability of concrete. Sand is also one of the commonly used raw materials in concrete. It is mainly composed of minerals such as quartz and feldspar, and has good filling and bonding properties. In concrete, the main function of sand is to fill the gaps between aggregates to improve the density of concrete. Water is one of the indispensable raw materials in concrete. It can cause a chemical reaction between cement and aggregate and play a role in solidification in concrete. At the same time, water can also make the fluidity of concrete better and ensure the uniformity and stability of concrete. The production of concrete also requires the addition of some auxiliary materials, such as accelerating coagulants, retarders, etc. These auxiliary materials can be selected according to the requirements of concrete so as to obtain the best concrete performance in different environments. Concrete is a building material composed of multiple raw materials such as cement, aggregate, sand and water. The performance of concrete depends on the ratio and function of various raw materials.
