technical field

The invention relates to the technical field of construction equipment, in particular to a concrete production and processing equipment.

Background technique

Concrete is one of the most important civil engineering materials of our time. It is made up of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and admixtures added when necessary in a certain proportion, after uniform stirring, compact molding, curing and hardening. artificial stone. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its consumption 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 it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material.

In 1900, the Universal Exposition demonstrated the use of reinforced concrete in many ways, causing a revolution in the field of building materials. In 1867, French engineer Ainabic was inspired to apply this material to house construction after seeing Monier's flowerpots, tubs, and water tanks made of barbed wire and concrete at the Paris Exposition in 1867. In 1879, he began to manufacture reinforced concrete floor slabs, which later developed into the use of concrete structural beams reinforced by steel hoops and longitudinal rods for the entire building. Concrete can be traced back to ancient times, and the cementitious materials used in it are clay, lime, gypsum, pozzolan, etc. Since the emergence of Portland cement in the 1820s, it has been widely used because the concrete prepared with it has the strength and durability required for engineering, and the raw materials are easily available, the cost is low, and the energy consumption is low in particular. (See Inorganic Cementitious Materials). At the beginning of the 20th century, some people published theories such as water-cement ratio, which initially laid the theoretical foundation of concrete strength. Later, light aggregate concrete, aerated concrete and other concrete appeared one after another, and various concrete admixtures also began to be used. Since the 1960s, water-reducing agents have been widely used, and high-efficiency water-reducing agents and corresponding fluidized concrete have appeared; polymer materials have entered the field of concrete materials, and polymer concrete has appeared; a variety of fibers have been used to disperse and reinforce fiber reinforced concrete. . Modern testing techniques are also increasingly used in the research of concrete materials science.

Inorganic cementitious materials such as cement, lime and gypsum are mixed with water to make the concrete mixture plastic; and then the strength is generated by chemical and physical chemical coagulation and hardening. Generally speaking, drinking water can meet the requirements of concrete mixing water. Excessive amounts of acids, bases, salts, and organics in water can have detrimental effects on concrete. Aggregate not only has a filling effect, but also has an important influence on the properties of concrete, such as bulk density, strength and deformation. In order to improve some properties of concrete, admixtures can be added. Because admixture has obvious technical and economic effects, it has increasingly become an indispensable component of concrete. In order to improve the workability of the concrete mixture or the performance of the hardened concrete and save cement, finely ground mineral materials, admixtures, can also be added during concrete mixing. It is divided into two categories: active and inactive. The nature and quantity of admixtures affect the strength, deformation, heat of hydration, impermeability and color of concrete.

When preparing concrete, first of all, according to the requirements of the project, such as workability, strength, durability, etc., the raw materials should be reasonably selected and the mixing ratio should be determined to achieve the purpose of economical application. The design of concrete mix ratio is usually carried out according to the requirements of the water-cement ratio law. The calculation of the amount of material mainly uses the assumed bulk density method or the absolute volume method.

Concrete mixer: According to different construction requirements and conditions, concrete can be mixed at the construction site or in the mixing station. The concrete mixture with better fluidity can be mixed with a self-falling mixer; the concrete with less fluidity or dry hardness should be mixed with a forced mixer. Before stirring, the ingredients should be mixed according to the requirements of the mixing ratio, and the weighing error should be controlled. The feeding sequence and mixing time have an impact on the quality of concrete, which should be strictly controlled so that each component material is mixed evenly. Commercial concrete is to supply certain required concrete to the construction site by means of centralized mixing. It includes processes such as mixing, transporting, pumping and pouring of the mixture. The only requirement of commercial concrete in the market competition is to ensure the lowest cost and selling price under the premise of ensuring workability, strength and durability. The technical way to reduce costs is to choose the right raw materials and mix proportions.

Sand and gravel cannot be screened during concrete production, resulting in unguaranteed product quality and low production efficiency. Therefore, the device can be designed to quickly produce concrete and classify sand and gravel to produce different specifications of concrete. concrete.
