Development status of commercial concrete mixing plant in China

Author: admin Release time: November 8, 2016 Number of visits:

Concrete mixer and other mixing equipment have been developed for many years in China. Although the concrete industry has been developed for more than 20 years in China, there is still a certain gap between the overall level and the world level, and it is still in the primary stage compared with many developed countries. The application of concrete in China is still in the stage of development in terms of experimental technology, production technology and construction technology. The development of various regions in China is also very uneven, especially in some small and medium-sized and remote areas.

Since the implementation of the market economy in which five kinds of ownership coexist, it is not only the construction enterprises who are optimistic about the concrete industry, but also the investors from all aspects of society. In the process of construction and development of many cities in China, the standardized management of construction industry has not been established and perfected. The production and application of ready mixed concrete, a more important, key and active semi-finished material in building structural engineering, poses a potential threat to the quality of structural engineering. The market competition is first of all the competition of professional and technical personnel. In China's colleges and universities, there are few cement products professional, after years of practice, experienced professional and technical personnel is extremely scarce, the training of professional and technical personnel is far from meeting the needs of the rapid development of enterprises in this industry. Take Beijing as an example. In the late 1990s, there were only dozens of concrete production enterprises in Beijing. Since the beginning of the 20th century, especially since Beijing won the right to host the 2008 Olympic Games, it has developed to more than 200. The number of new mixing plants has reached 2-3 times of the total in the past 20 years. However, the number of professional and technical personnel with a certain level is limited. Is it satisfied The requirements of the industry management department on the qualification level.

At present, many managers of commercial concrete mixing plant have weak professional knowledge and quality awareness, especially in the developing small and medium-sized cities and regions. Even the managers of some concrete enterprises in more developed areas do not have enough understanding and understanding of the concrete industry and concrete products, the professional configuration of equipment selection is not high, the measuring instruments are not accurate, and even do not conduct any inspection at all. The modern computer office means do not know, or even do not accept. The concrete production is regarded as the traditional, simple and general building materials, the simple pursuit of greater interests, not serious implementation of norms and standards, fraud, shoddy, eventually lead to all kinds of engineering quality accidents.

The managers and commanders of the production, technology, quality, equipment and materials departments of concrete enterprises should constantly sum up experience, constantly explore and accumulate experience, because in the process of concrete production and construction, due to a little negligence, the concrete produced may become waste products, affecting the quality of the whole project. The reasonable command and mobilization of vehicles and manpower to meet the needs of the project, such as the reserve of materials, the integrity of equipment, the quality and skills of technical personnel, the change of weather, the influence of traffic status, the site construction position and construction conditions, etc., are the final embodiment of the scientific management level of commercial concrete mixing station managers.

The scientific mix design of commercial concrete is the embodiment of the technical strength of a concrete production enterprise. Operators should implement the idea of serving the next process, and the difficulty of construction site should be considered in the design of proportioning. Therefore, according to the problems reflected by the construction unit, the commercial concrete production enterprises should carefully study the proportioning design and find out the rules through the test, so as to make the ratio more scientific and reasonable, and ensure the construction more smoothly.

The comprehensive quality training and improvement of enterprise staff and on-site construction team is also a very important link. Concrete is a fixed time, fixed point, quantitative embodiment in a project site, is a continuous uninterrupted semi-finished product, it is determined by dozens or even hundreds of natural, mechanical, human factors and links. Every link is more important, and all posts are more critical. There is no primary or secondary point on this issue. Because the concrete production process is a continuous operation mode, to complete the production of semi-finished products, it will take 1-2 months or even longer time of maintenance to form the final product. Therefore, the managers of concrete production enterprises must pay attention to the on-the-job training of employees as a more important work, put it at the top of the agenda, and give up the current idea of valuing profits and neglecting management as the fundamental guarantee for the sustainable development of enterprises.

With the development of concrete industry, China has also led to the development of concrete supporting facilities, concrete mixer, concrete mixing station, bulk cement silo.
