gradually recognized and valued by people because of its excellent performance in saving resources, protecting the environment, ensuring the quality of construction projects and realizing the reuse of resources Its development not only fully embodies the national strategic policy of energy conservation and emission reduction, but also one of the important measures to promote the development of circular economy Dry mixed mortar products have been widely used in Western Europe since World War II The technology is gradually mature, and the products are various, which meet the functional requirements of the project Since the end of last century, the application of dry mixed mortar in China has achieved remarkable economic and social benefits 3.1 background of the project 3.1.1 domestic form and current situation of construction industry in recent years, China's economic development is strong, and the construction industry is also developing rapidly driven by it It is estimated that the real estate area to be completed in Shanghai will reach 70-90 million square meters in the next five years, and that in Beijing will reach more than 130 million square meters The development plan of other regions is also very fast As China's economy has begun to take shape, the government and people are increasingly demanding on the quality of construction products and environmental protection At present, the annual output of cement in China is nearly 600 million tons, about 1 / 3 of which is used to mix mortar, and the annual demand for mortar is more than 1 billion tons At present, the vast majority of construction mortar used in China's construction industry is temporarily mixed in the construction site, with large operation error, no guarantee of the quality of the finished product, and a large amount of mortar, which causes problems such as low construction quality, waste of resources, time and energy, environmental pollution, etc In some key parts of construction, such as tiling, waterproof, fireproof layer, secondary grouting of equipment foundation, etc., mortar with special performance requirements is required However, the traditional on-site preparation is difficult to achieve high quality, and it is easy to have quality problems This requires the development of ready mixed mortar At present, the commercial concrete has been widely used in many areas of our country, especially in the economically developed areas, which greatly improves the construction efficiency, reduces the cost, reduces the waste of manpower and materials and environmental pollution However, the application of dry mixed commercial mortar in China still lags behind In view of this situation, in 1999, the former State Building Materials Bureau listed "polymer dry mixed mortar" as a new type of wall material that was mainly developed in 2000 (see the directory of development orientation of new building materials and products) The regulations on energy conservation management of civil buildings (implemented on October 1, 2000) states that the State encourages the development of new heat preservation and insulation technologies and materials for energy-saving walls and roofs According to the Tenth Five Year Plan for the development of bulk cement, it is required to accelerate the development of ready mixed concrete and dry mixed mortar It is forbidden to mix concrete on site in the urban areas of municipalities directly under the central government, provincial capitals, coastal open cities and tourist cities from December 31, 2003 In other cities, it is forbidden to mix concrete on site in urban areas since December 31, 2005 On June 6, 2007, the Ministry of Commerce, * ministry, Ministry of construction, Ministry of communications, General Administration of quality supervision, inspection and environmental protection and other six departments issued the notice on forbidding mortar mixing on site in some cities within a time limit According to the notice, Beijing and other ten cities will officially start the prohibition of mixing mortar on the construction site from September 1, 2007 Ready mixed mortar will be used in the project, and other 117 cities will also implement the "Prohibition" in batches in the next two years This is the development of bulk cement promoted by the Ministry of Commerce, the Ministry of construction and other departments after the prohibition of mixing concrete on the site in some cities in 2003 Another important measure is to implement the requirements of "starting from the use link, further increase the promotion of bulk cement" put forward by the State Council in 2005, to implement the scientific outlook on development, and to promote energy conservation and emission reduction According to the requirements of the notice, from July 1, 2009, there are 84 cities (the third batch) in China, such as Changchun, to start the mortar "ban" So far, 127 cities across the country have carried out the work of "forbidding the mortar from appearing" This is a good time for developed cities in coastal areas and inland cities to vigorously develop commercial dry mixed mortar The policy that the development of dry mixed mortar can enjoy the government discount loan of bulk cement special fund has been clearly stipulated in the document caizong [2002] No 23 jointly issued by the Ministry of Finance and the State Economic and Trade Commission § 3.2 project introduction and foreign development and process § 3.2.1 project introduction dry mixed mortar is a kind of mortar that premixes cement, sand, mineral powder, polymer additives, etc in the dry state and packs or bulk in the form of dry mixed materials When using, just add water to mix, and the quality is guaranteed The product categories of dry mixed mortar are complete, and the product varieties of dry mixed mortar are complete, which can meet the requirements of various functions and strength, and can also develop functional products according to the needs; 2 Ordinary dry mixed mortar: masonry mortar, plastering mortar, ground mortar, etc 2 Special dry mixed mortar: facing type: interior and exterior wall putty, color decoration dry mixed, Powder coating bonding class: porcelain board binder, joint filler, insulation board binder, etc other functional materials: insulation mortar, self leveling floor material, repair mortar, waterproof mortar, Compared with the mortar prepared at the construction site, the dry mixed mortar has the following advantages: (1) the quality is stable and reliable, which can meet different functional and performance needs, and improve the project quality (2) The improvement of work efficiency is conducive to the application of automatic construction machines and tools, and changes the backward way of traditional construction (3) It has a strong adaptability to the new wall materials and is conducive to the promotion and application of the new wall materials (4) In the construction process, the consumption is less than the traditional way, which can save resources (5) Improving the construction environment is conducive to environmental protection (6) Easy to use § 3.2.2 development of dry mixed mortar in foreign countries dry mixed commercial mortar originated in Finland in 1958, * factories specialized in producing wall mortar, namely putty Later, tile adhesive and other dry mixed products gradually appeared From the 1960s to the 1980s, and then to the 1990s, the dry mixed market has matured in developed European regions such as Germany and Finland The use of dry mixed products accounts for 1 / 3 of cement sales Because of its high unit value, the profit is much higher than 1 / 3 of cement industry profit According to statistics, in these areas, nearly two dry mixing plants are needed for every one million people For example, there are 180 professional dry mixing mortar factories in Germany, 10 dry mixing mortar factories in Finland Cement enterprises and building materials chemical companies benefit greatly from this The dry mix industry in Asia started late, but its development speed is very fast In 1984, Singapore established * dry mix plants, so far, there are 6 dry mix mortar production plants The dry mixing industry has grown rapidly in Singapore, Malaysia, Thailand, Taiwan, Hong Kong, South Korea, India and other countries and regions, and has formed a market scale In these regions, high value-added products such as tile adhesive, wall color mortar and so on have begun to replace traditional products, and low value-added products such as primer mortar, masonry mortar, floor mortar and so on are also gradually popular § 3.2.3 current situation of domestic industry research on dry mixed mortar technology in China started in the 1980s, and it was not until the end of 1990s that a certain scale of dry mixed mortar manufacturing enterprises began to appear Since the beginning of the 21st century, under the dual role of market promotion and policy intervention, the dry mixed mortar industry in China has gradually transited from the market introduction period to the rapid growth period With the promotion of relevant national policies, the introduction of foreign advanced concepts and technologies, and the active efforts of governments at all levels, production enterprises and users, China's dry mixed mortar industry has developed steadily A complete industrial chain of research and development, equipment manufacturing, raw material supply, product production, logistics and product application of dry mixed mortar has been initially formed According to the statistical data in 2008, there are 196 dry mixed mortar production enterprises with a design capacity of 21.771 million tons and an actual output of 6.406 million tons At present, the exterior wall insulation system is widely used in dry mixed products in China The state vigorously promotes building energy conservation, and the amount of heat preservation products is huge After the development of the northern region, it can be concluded that the space of the thermal insulation system in the southern region is huge, far larger than the external wall putty, adhesive and other markets, and there is a trend of merging with the coating market Secondly, adhesive products, such as ceramic tile adhesives in Shanghai, Beijing and other places, are sold at a price of about 1000 yuan / ton, up to 2000-3000 yuan However, due to the simple construction, low consumption per unit area, high construction quality and high efficiency, they are widely used in construction In recent years, China's economic development is rapid and has begun to take shape The requirements for the quality of construction products and environmental protection are higher and higher In addition, the introduction of policies and regulations on resource conservation and environmental protection by governments at all levels has strongly promoted the dry mixed commercial mortar industry Some provinces or regions in China have also successively issued relevant policies to promote the dry mixed mortar industry At present, domestic and foreign manufacturers are preparing to invest and build factories in Shanghai, Beijing, Guangzhou and other major cities or their surrounding areas to carry out large-scale production and earn profits from this emerging industry § 3.3 investment prospect: the annual output of cement in China is 700 million tons If the annual production of dry mixed mortar can reach 1 / 3 of the total output of cement according to the development of foreign mature market, the annual production of dry mixed mortar will reach more than 200 million tons At present, the output of factory produced dry mixed mortar is only millions of tons, which is undoubtedly a potential market to be developed 1 Macro environment analysis the direction of national economy and social development in China is to build a resource-saving and environment-friendly society and promote the coordinated development of economy, society and environmental protection The 11th Five Year Plan period is the key period for China to build a well-off society in an all-round way, as well as the key period for turning economic and social development into a scientific development track In the next 15 years, China's economic development will still be in the first place
