Chapter 326 The History of Concrete Development Abroad

The effect of Li Ruoyu's incentive method is obvious, and all the people, including Xie Zili, Zhou Xiaoxian and others, are excited, and they all shout loudly, they really feel that the future is very good.

Li Ruoyu smiled again: "We are not only the largest concrete group in the country, we will also enter construction-related industries, such as real estate development, construction machinery, etc." At present, we have reached an agreement with a well-known foreign construction machinery company to prepare a joint venture in China to produce concrete machinery. What do I mean by that? That is to say, you are the veteran employees of the company, and when the company grows in the future, you can also become a shareholder of the company and receive dividends. It's as simple as that. ”

Hearing Li Ruoyu say so excitedly, everyone couldn't help but applaud.

Li Ruoyu said: "Popularize the knowledge of the building materials industry to everyone." All building materials groups in the world have experienced such a development process from the production of a single building materials category to the joint production of upstream and downstream products. Among them, the Lafarge Group is a typical representative, which was founded in France in 1833 and has a history of nearly 180 years. In 1833, the company began a regular business of producing and supplying lime in a limestone quarry called "Lafarge" in the Ardèche region of France, and at the same time producing and supplying concrete aggregates; In 1887, Lafarge began the production and research and development of cement, and in 1908, high-alumina cement was invented, and large-scale cement production began. In the 50s, it began to develop abroad, and in 1956 it began to enter North America, and by the end of the 60s, it became the third largest cement producer in Canada! ”

"Lafarge Group becomes the world's largest cement producer and strengthens the Group's position in emerging markets. As one of the three main business divisions of Lafarge Group, Aggregates & Concrete ranks second in the world, with hundreds of mines and more than 1,000 concrete plants in 40 countries. In 1990, it had sales of $3 billion and employed more than 20,000 people. As a world leader in the building materials industry, Lafarge Group is at the forefront of the industry in all four divisions. Cement and roofing systems rank first in the world, concrete and aggregates rank second in the world, and gypsum building materials rank third in the world. Founded in 1833, the French Lafarge Group is a multinational conglomerate that has diversified into the building materials industry, and is a world leader in six major fields, including concrete, aggregates, gypsum, roofing materials and special building materials, in addition to cement. When we introduce you to this part of Lafarge's history, we should not forget that it first started in the mining and concrete aggregate industries, and this history is very instructive. It is important to explain the fundamental position of concrete in the construction industry. ”

Many employees heard of Lafarge for the first time, after all, Lafarge had not yet entered China, and many employees were extremely surprised by such a huge company. More than a thousand concrete plants, what is this concept? Now there are less than 100 concrete batching plants in the country! This shows that there must be huge space for the development of concrete in China.

Li Ruoyu continued: "However, it is not enough to observe the development process of the foreign concrete industry only from the formation and development of the ready-mixed concrete industry itself. After the rapid development of the 60~70s, the ready-mixed concrete industry in Europe, America and Japan has not changed much in addition to the scale, and the biggest change is the change in the structure of the concrete industry, mainly the integration of collectivization and upstream and downstream enterprises. The large-scale merger of Tongguò has formed the industrial structure of the concrete industry group in the true sense. Among them, in addition to a large number of mergers with cement companies, the concrete industry also merges with other raw material companies such as sand and gravel aggregates, admixtures, mineral admixtures, etc.; At the same time, many European and American concrete industries have gradually merged with their downstream industries - prefabricated products enterprises and gradually entered the field of concrete construction, managing the concrete construction process in the construction project and contracting the construction of concrete structures. Form a large industrial group with the integration of the entire concrete industry chain. This trend has been going on since the beginning of the ready-mixed concrete industry. ”

Li Ruoyu looked at Anna and said, "Miss Anna, you are the manager of the largest concrete machinery group in Europe, tell our employees, is that the case?" ”

Anna said with a smile: "That's right, our company also conducted production research in a number of French concrete companies at that time, and knew that since the early eighties, the French concrete mixing plant will directly take over the concrete construction of the construction site after the construction of the steel formwork project is completed, that is, the concrete structure construction team of the construction site is sent by the concrete company. The concrete batching plant directly grasps the construction drawings and the implementation rules of the construction contract, and plans and schedules the production of the whole concrete in combination with the company's production plan and construction contract. The personnel who manage the construction and operate the construction at the construction site are all construction teams under the concrete company. In addition to the construction personnel of the mixing plant management on the construction site, the personnel of the project supervision party entrusted by the project owner must also be present, and their responsibility is to supervise the concrete materials and construction operations entering the site. In addition, there are occasional government supervisors who inspect the quality of the project from time to time. The concrete specimens retained on site are generally taken back by the concrete batching plant as on-site samples for testing and recording under standard curing; The supervision party regularly entrusts a third-party testing agency to conduct sample sampling and engineering structure quality inspection, and the random inspection method is directly taken by the testing agency on site for sampling and molding, and brought back to the testing agency for maintenance and testing. Quality checks on engineering structures are done only when necessary. There is no need for maintenance equipment on the site. In other words, the mixing plant must do a good job of working performance inspection before the concrete leaves the station, and can do or not do work performance verification after arriving at the construction site. However, it is necessary to keep the concrete specimens and bring them back to the mixing plant for strength and special performance inspection, as the basis for project acceptance. This process is supervised by the project supervisor and is legally bound by the construction contract between the two parties. In the event of a dispute, the supervising party has full authority to deal with it in accordance with the construction contract until resorting to law. That is to say, the mixing plant is fully responsible for the quality of the concrete leaving the factory and the quality of the construction, that is, it is directly responsible for the acceptance of the project. ”

Li Ruoyu nodded and said: "We are different in China, the final quality of concrete is actually the responsibility of the concrete producer and the concrete construction party, and often only one party is actually responsible. As a result of this development, the vast majority of European construction engineering companies, unlike the structure of China, are not the general contracting companies of all construction projects, but have evolved into highly professional professional companies, such as rock foundation engineering companies, steel formwork engineering companies, maintenance and waterproof engineering companies, decoration engineering companies, plumbing, electricity and drainage engineering companies and other professional companies, they have the same engineering team as concrete companies, which have completely under their own control.
