The birth and development of concrete admixtures in our country was mainly in the 1970s and 1980s. Since then, our construction pace in China has gradually grown in the country, and the construction industry has become more powerful because of the embellishment of small admixtures. As a result, admixture and small material production companies abound, and the birth of admixture companies has contributed to the construction of bridges and so on.
Admixtures are the sixth component in concrete besides sand, gravel, cement and other materials. Compared with sand and gravel cement companies, admixture companies are far different in terms of scale and output value, which also creates The admixture is weak and can be bullied. Therefore, there is a saying that has been circulating in the world: “If you want to suffer more, mix concrete; if you want to suffer more, make admixtures.” The editor has also been involved in concrete admixture technical services for several years, and has long since washed his hands. Thinking about the past, he summarizes some of his experiences for the benefit of readers.
1. Be familiar with the basic knowledge of cement silicate, concrete building materials, national standards, etc.
Admixtures are a special multi-disciplinary industry. “, “Building Materials”, and “Principles and Applications of Concrete Admixtures” are regarded as the three “Sunflower Collection” of the admixture industry. The National Standards for cement, sand, gravel, concrete and other raw materials are the official language in the world. Only by mastering the words and phrases of this language can we communicate effectively with technical personnel in the industry.
2. In-depth understanding of concrete admixture compounding and the characteristics of each auxiliary material
The compounding of admixtures is an essential skill for walking in the world. The solid and reliable master material is the basis of all compounding and the inner strength of all moves. The various characteristics of the auxiliary materials are the moves of your martial arts. Only by combining both can we be able to cope with the changes and challenges of other concrete raw materials.
3. Excellent communication skills
No matter how high your martial arts skills are, it is essential to communicate with the technical leaders of various mixing stations and engineering projects before testing. . The editor has concluded over the years that many so-called technical problems are caused by poor communication and differences in information understanding. Communication is not cheating! Don’t regard admixtures as “miraculous water” that can solve all concrete problems. Equal and pragmatic communication is the key to solving technical problems.
4. Adapt to long-term wandering in rivers and lakes
For technical services serving engineering projects, wandering in rivers and lakes and even “abandoning one’s wife” are basic qualities. Many engineering projects are located in remote areas with no access to villages or shops. It is common for people to ride motorcycles or three-wheelers. It is necessary to be mentally prepared for this. If conditions permit, some companies may conduct regular outdoor training. .
5. Master the testing methods and methods of concrete admixtures
At present, the concrete admixture industry is developing rapidly, and the total amount of talents and personnel quality required can no longer meet the needs of economic and social development. , especially the shortage of technical talents with formal training and job certificates for employees in concrete admixture companies. Holding such training courses can enable practitioners to understand relevant professional knowledge and skills, master the methods and means of concrete admixture testing, and improve the professional quality of practitioners to adapt to market demand. At the same time, she hopes that the students will study hard, master more business knowledge, improve their business level, and make their own contributions to the development of the concrete admixture industry.
6. Main work content
Go to concrete mixing stations or engineering projects to increase admixtures. For example, if you are from an admixture company, you want to go to customers who use your products to use your products. The product can adjust the state of concrete, such as how much slump can be achieved, how much loss can be controlled in 1 hour, whether there is no slurry or segregation, etc. Determine the formula of the admixture in this state, what to use for the mother liquor, how much to use, how much to use for the small ingredients, report back to the unit, produce, and then supply. It is necessary to understand the common knowledge of admixtures, the mix ratio and adjustment measures of concrete, etc.
