Concrete admixture wrapping agent, water-retaining and viscosity-increasing agent, resists segregation and bleeding, improves concrete fluidity

Anhui Yulong New Material Technology Co., Ltd. is an enterprise specializing in water-retaining tackifiers and anti-segregation agents. Our company produces water-retaining tackifiers. This product has excellent water retention, workability, pumpability and adaptability. It can improve the water retention of concrete and mortar, avoid segregation and bleeding; improve the sensitivity of water-reducing agents and improve the anti-sag properties of accelerating agents. Used in the compounding and synthesis of water reducing agents and accelerating setting agents, it can not only improve product performance but also reduce production costs.
Concrete admixtures, water-retaining and tackifiers, resist segregation, prevent bleeding and improve concrete fluidity

1 Analysis of the development history of commercial concrete and industry characteristics
Commercial concrete, also known as ready-mixed concrete (RMC) ), first appeared in Europe. Since the world's first commercial concrete factory was built in Germany in 1903, the commercial concrete industry has experienced more than a hundred years of development. The product types have gradually become richer, from traditional ordinary concrete to high-performance concrete, green and environmentally friendly concrete. Concrete direction transformation.
The main characteristics of its industry are:
(1) They are different from the modern building materials industry and belong to the construction industry. The production scale of a single station in a region will not be very large, and the transportation distance cannot be exceeded. For a long time, the door-to-door service method of product delivery determines that they must be dispersed and as close to the user as possible.
(2) They completely serve the civil construction projects in the region. The cost of products and raw materials must be considered, and the ease of availability must be considered, so they are highly local.
(3) Their development is affected by the development of the construction industry. The phenomenon of credit for raw materials and products is very common, and is greatly affected by the national economic macro-control, especially real estate regulation.
(4) The quality of their products needs to go through various inspections. In addition to passing the inspection process of the concrete mixing station itself, it also needs to go through the quality inspection of the concrete engineering entities produced. Product quality is a lifelong responsibility system.
(5) The production method of commercial concrete determines that in addition to having close production ties with the upstream and downstream of the industry, they must also be united within the regional industry. They not only cooperate with each other, but also have a clear division of labor in order to work together. Survive.
2 Analysis of the Development Characteristics and Trends of International Commercial Concrete
In developed countries abroad, commercial concrete already occupies an absolute advantage in the total concrete production. By the 1980s, the application volume of commercial concrete in economically developed countries had reached 60% to 80% of the total amount of concrete. In the international commercial concrete market, Europe’s experience is most worth learning from. Their main considerations in developing the commercial concrete industry are:
(1) Pay attention to the selection of factory sites, and generally choose the layout along traffic arteries to facilitate the transportation and unloading of raw materials such as cement, sand, and stone. In addition, the network of mixing stations Arrange it as close to users and the market as possible.
(2) The supply varieties of concrete companies are becoming increasingly diversified, ranging from various grades of concrete, special concrete, building mortar, to concrete blocks and products to meet the needs of different users.
(3) The scale of each mixing station is generally small. Most of them are equipped with one production line in one station, and not many are equipped with two lines in one station. The production process layout is generally very compact, occupying a small area, and often adopts temporary, demolition and mobile designs, such as offices and laboratories using containers that are easy to load and unload.
(4) The mixing station in each concrete company generally has a division of labor between a central station and a satellite station. In addition to production, the central station also has the functions of raw material formula design, product inspection, and production scheduling. The satellite station receives production instructions through the internal network and performs concrete production. It has no other functions and functions as an auxiliary station. </p
