Development history and current situation of dry-mixed mortar technology in Europe
Although the history of dry-mixed building materials entering China’s construction industry is not very long, it has been promoted in some big cities, and has increasingly won more and more recognition and market share with its superior performance. Therefore, the dry-mixed building materials production industry will inevitably achieve considerable development in the future.
It is therefore essential to overcome and balance the differences that exist between Europe and China. The difference between the dry-mixed mortar industry in Europe and China lies in: the dry-mixed mortar production equipment to be built, the admixtures required for the production of dry-mixed mortar products, and the requirements for each individual dry-mixed mortar product, the dry-mixed mortar product mixing plant The construction mixing machines used are also different.
Dry-mixed building materials originated in Europe, but their development in Europe is different from that in China. In Europe, before the appearance of dry-mixed mortar, people have already completed a large number of modern buildings. People clearly know what materials are needed, what characteristics the materials should have, and what functions they should achieve. The quality standards for manual construction of mixed mortar on the site have also been established. mature. With the continuous development of industrial medicine that pays attention to the health of workers, and due to the consideration of wage costs, machines are inevitably used in the construction of building materials. Therefore, people must design corresponding production equipment for the production of building materials. That is to say, before the production of dry-mixed building materials, European employment already had performance standards for various building materials, requirements for construction bases, raw materials for production, and standards for technical functions and visual effects. In this way, the goal of building materials production is very clear, namely:
Develop dry-mix mortar products suitable for machine application and to meet known functional requirements. This only requires the production equipment to meet:
In dry-mix mortar plants, products of known function and utility are produced in dry-mixed form.
Generally speaking, if someone decides to build a dry-mix mortar factory, it is firstly because the investor already possesses certain raw materials, or can produce cheap raw materials himself, and secondly, he already knows in what form (composition, insulation and No, color, etc.) what kind of product to produce, and the volume to be achieved.
According to these specific conditions, the equipment supplier can implement the design in detail.
Of course, many newly developed dry-mixed building material products appeared later, and many corresponding product performance standards and construction specifications were also issued. Products are used together to develop different dry blend product systems.
Due to such developments, and due to rising wage costs in Europe, machine-applied dry-mix mortars have almost completely replaced construction mortars mixed on site, and dry-mix mortars have been machine-constructed as much as possible. However, in view of the specific conditions of different construction sites, such as in the renovation of old buildings, small quantities of dry-mixed mortar are also applied manually. The ready-made masonry or plastering mortars are completely gone. Whether it is an enterprise that manufactures dry-mixed mortar production equipment, a manufacturer that produces dry-mixed products, or an enterprise that designs and produces dry-mixed construction machines and tools, it has achieved great development and perfection. They know very well what kind of products should be produced for what reason, and in what form to achieve the predetermined goals.
The application of dry mix products has also been specialized. Some construction teams today are only responsible for putting up the walls, that is to say, they only use masonry mortar in the construction process; there are also other construction teams that specialize in plastering the walls. In recent years, there has been a professional division of labor for interior and exterior wall plastering in the wall plastering construction team, and even a construction team specialized in overlay plastering to complete the surface layer construction of wall putty or facing mortar. Every builder is very skilled in his work. The same specialization trend has also created a professional thermal insulation joint system and thermal insulation mortar construction team. The construction of floor materials, especially flow and self-leveling materials, is based on a professional construction team and its astonishing construction speed.
Rising wage costs and wage surcharges have made manual construction unaffordable, so the goal is now to go as fast as possible with as little labor as possible.
The price pressure caused by the labor of construction workers will naturally be passed on to the material producer, that is, the dry-mix manufacturer, which leads to the formation of larger and larger dry-mix mortar factories in the market, and they can always produce specific products quickly. It is worth noting that a single dry-mix manufacturer only provides one or several specific products at favorable prices, rather than all types of dry-mix products, so they can be called specialized dry-mix production plants.
The individual dry blend production plants exchange products with each other in order to meet the needs and wishes of all customers.
Dry-mix equipment manufacturers, dry-mix mortar manufacturers, dry-mix product constructors and construction machine manufacturers in the same market chain must make corresponding adjustments. Every individual is clear about his goals, what he needs, and what is beyond his ability.
From the origin and development of the above-mentioned dry-mixed building materials in Europe, it is not difficult to see that dry-mixed mortar manufacturers are very clear when ordering production equipment, which products to produce, and most of them also know what kind of equipment is needed. They pass this information to the equipment manufacturers, and the equipment manufacturers then design special dry-mixed mortar production equipment that meets their wishes according to their wishes.
Although forward-looking planning, market research, and close contact with block material (bricks, lightweight building materials, etc.) products have no impact. Retrofitting equipment, expanding the production range, or changing dosage distribution is extremely difficult, at least not yet possible in existing dry blend production facilities. Moreover, all transformation work must be carried out in a state of shutdown.
