Concrete is one of the most important materials in contemporary civil engineering. It is an artificial stone made by mixing cementitious materials, aggregates and water in a certain ratio, vibrating and molding, and producing it in a concrete mixing plant. Concrete has the characteristics of abundant raw materials, low price and simple production process, thus making its use more and more; at the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength levels, making its use very wide, not only in a variety of civil engineering use, that is, in the shipbuilding industry, machinery industry, marine development, geothermal engineering, etc., concrete is also an important material.
Ready-mixed concrete is the largest user of bulk cement, and vigorously developing ready-mixed concrete is the only way to develop bulk cement. It is an effective way to realize the clean production of cement, and the high or low open rate of cement reflects to a certain extent the technical progress and civilized production level of enterprises. The project plays an important and positive role in regulating and accelerating the healthy and rapid development of the bulk cement industry in Kaifeng.
Concrete: It is the collective name of engineering composite material which is made of cementing material to glue the aggregate into a whole. The term concrete is usually used to refer to cement as the cementitious material, sand, stone as the aggregate; and water (with or without additives and admixtures) in a certain ratio, mixing, molding, maintenance and obtained cement concrete, also known as ordinary concrete, which is widely used in civil engineering.
Commercial concrete is concrete that is produced at a concrete mixing plant and sold as a commodity. Compared with the concrete mixing plant on site, commercial concrete is produced by professional producers, most of these companies have advanced production equipment, accurate measurement, uniform mixing and high quality. There is a perfect quality testing system to ensure the quality. By purchasing commercial concrete, construction units can reduce the piling of construction materials on site, which is conducive to environmental protection and civilized construction. The specific specifications are further divided into C15, C20, C25, C30~C80.
Features of commercial concrete:
1. Since it is centrally mixed, it can strictly control the quality of raw materials and mix ratio online, which can guarantee the quality requirements of concrete;
2. The requirement of good workability of the mix, i.e. high fluidity, low slump loss, no water secretion and no segregation, good pumpability;
3. economy, requiring low cost and high performance to price ratio.
Commercial concrete, also known as ready-mixed concrete, its emergence and can be said to be a "revolution" in the history of concrete development, is the concrete industry to modernize and scientific sign. The essence of commercial concrete is to separate the main building material from the traditional construction system, from preparation, mixing to transportation and a series of production links, and become an independent economic accounting of the construction materials processing enterprises – ready-mixed concrete mixing plant or concrete company. The commercialization of concrete production can be highly specialized and centralized for construction projects to save cement and sand materials, improve project quality, improve construction organization, reduce labor intensity, reduce production costs, and also because it can save land for construction, improve labor conditions, and reduce environmental pollution and benefit mankind. The same day inch, the promotion of commercial concrete is also an important precursor measure for the promotion of bulk cement, and is therefore highly valued by the relevant state departments.
Centralized concrete mixing plant is a major change in the production method of construction projects. The number and proportion of applications of commercial concrete in a country marks the level of industrial production of concrete in that country.
Commercial concrete can generally improve labor productivity by more than double the savings of cement 10% to 15%, reducing the cost of the project by about 5%. At the same time can also ensure the quality of the project, save construction land, reduce dust pollution, to achieve civilized construction. By the 1980s, the application of commercial concrete in economically developed countries has reached 60% to 80% of the concrete.
In summary, if the construction of a product market positioning, will focus on serving the new county construction, but also the plant site as the center, to the surrounding 30 km range of radiation, the formation of a strong brand effect, for the local and surrounding regional markets to provide high-quality ready-mixed commercial concrete, to better serve the infrastructure construction projects, how should be designed? What are the design principles, there are the following 7 aspects, let’s analyze them together!
7 principles of concrete concrete mixing plant design:
1. to ensure that the design conforms to national regulations and norms on fire protection, environmental protection, energy conservation and emission reduction, labor protection, etc.;
2. Optimize the process layout plan, reasonably and economically use the site, combine advanced with economy, and minimize the floor space.
3. fully combine with local natural conditions, further optimize the design of building structure and reduce the amount of civil engineering to reduce the cost of building works under the premise of meeting the process.
4. Carefully design, carefully construct, shorten the construction cycle, and reduce the project investment.
5. Adopt energy-saving process and energy-saving equipment, industrial equipment selection to reach the domestic advanced level, reduce the operating cost of enterprises and enhance the competitiveness of enterprise products in the market.
6. Adopt advanced and reliable computerized centralized control system to ensure reliable operation of process production, stable working condition, energy saving and high efficiency, optimize control, realize modernization of management, improve labor productivity, minimize operation post fixing, and reduce operation cost.
7. pay attention to the environmental protection design of the production line itself, strengthen the management of dust and noise, and promote the sustainable development of the enterprise. The project construction can effectively achieve the environmental protection facilities and the main project design, construction and operation at the same time, the emission of various pollutants can reach the national standard, to achieve clean production, civilized operation.
