However, due to the transitional construction from 2010 to 2016, in the long run, the consumer demand of the housing industry will slow down and the main growth areas will shift to non housing industries.
Followed by Western Europe (10.4%) and North America (10.1%).
The stable development of domestic real estate and construction industry has also driven the continuous growth of the scale of building materials market, and promoted the continuous expansion of the scale of concrete admixture market to a certain extent, from 52.92 billion yuan in 2015 to 64 billion yuan in 2020, with an average annual compound growth rate of about 3.9%..
Although China has made great progress in civil engineering and construction technology, it still lags behind developed countries in some special chemical fields with high added value.
Due to the increasing demand for high-quality concrete structure, a large number of first and second-generation concrete superplasticizers have been replaced by the third-generation polycarboxylate ether (PCE) superplasticizer products; However, due to the more efficient effect of the third generation water reducing agent, the consumption of active ingredients of concrete admixture increases slowly, from 5 million tons in 2016 to 5.7 million tons in 2020.
As an enabling material, special construction chemicals can make the manufacturing of existing building materials easier.
01 most of the major consumer countries in the international market come from large multinational manufacturers in the northern hemisphere, with only a few.
In the same year, China’s consumption of special construction chemicals accounted for 59% of the total global consumption, making it the largest consumer of this product.
Worldwide, the construction industry is one of the most important components of the economic structure of various economies, accounting for about 13% of the global GDP.
In the next 2-3 years, the consumption of special construction chemicals is expected to continue to grow at an annual rate of about 4%.
At present, only a few large multinational enterprises are involved in this field, such as BASF, sika, Mapei, GCP, RPM, Henkel, DENKA, flowric and Carlisle.
In recent years, driven by the rapid development of infrastructure and real estate industry, China has become the world’s largest consumer of special construction chemicals.
From 2020 to 2025, the overall global construction market will maintain a compound annual growth rate of 3.4%.
Among the five special construction chemicals, concrete admixtures account for about 75% of the total consumption, followed by special coatings, adhesives / sealants, asphalt additives and isolation materials.
From the perspective of market segmentation, there are many kinds of special construction chemicals on the market in China, among which concrete admixture is the main product, which is known as the fifth element of concrete components.
First, it can reduce the use of natural resources in construction projects; Secondly, reduce the time, capital and energy consumed during the construction period and the whole construction life cycle; Third, it can improve the performance of some traditional low-value building materials (such as gypsum) and make them more valuable in architecture.
China’s construction expenditure grew at an annual rate of 11% from 2006 to 2016, but has slowed to 6-7% from 2017 to 2020.
Concrete admixtures are still the most important special construction chemicals.
The industry consumes a lot of chemical products every year.
It is estimated that China’s construction expenditure will grow at an average annual growth rate of 4-5% from 2020 to 2023.
In 2020, the consumption of special construction chemicals in China will be about 7.6 million tons, and the market scale will reach nearly 93 billion yuan.
These companies specializes in the production of concrete admixtures, asphalt emulsion, adhesives / sealants, specialty coatings, spray insulation foam and other products.
In 2020, the total value of the global special construction chemicals industry is close to US $42 billion.
In recent years, the market supply of concrete admixtures in China is sufficient.
In the future, the global consumption and forecast of special construction chemicals are shown in the figure below.
At present, the major consumer countries of special construction chemicals, except Australia, Indonesia and Brazil, are mostly from the northern hemisphere.
02 the domestic market is the world’s largest consumer of special construction chemicals, and the future consumption will continue to grow steadily.
In 2018, the global market scale of special construction chemicals was about US $38 billion, with a total consumption of 13 million tons, including 8 million tons of concrete admixtures, accounting for 62%; The consumption of asphalt modifier is 1.04 million tons, accounting for 8%; The consumption of adhesives and sealants is 1.74 million tons, accounting for 13%; The consumption of protective coatings is 1.35 million tons, accounting for 10%; The consumption of thermal insulation materials is 870000 tons, accounting for 7%.
Due to the high degree of specialization in the construction chemicals industry, there are a large number of specialized construction chemicals suppliers for different segments of users, including many small and medium-sized enterprises operating in a certain region.
The Chinese national standard defines “concrete admixture” as “the components added to the concrete mixture during mixing to affect / improve the dictation parameters / characteristics of the concrete mixture”.
“Background brief description: special construction chemicals products include concrete admixtures, asphalt modifiers, adhesives, sealants, protective coatings, thermal insulation materials and other products.
Among them, the growth of construction and construction chemical industry in developing countries (such as China, India and Arabia) is expected to be higher than the global average.
As the government pays more attention to the manufacturing industry and infrastructure construction in rural areas, it will further promote the regional development of inland areas and drive the increase of the demand for special construction chemicals.
The output of concrete admixtures in China has grown from 12.243 million tons in 2013 to 14.88 million tons in 2020, with an average annual compound growth rate of about 2.8%.
As enabling materials, the use of special construction chemicals plays a vital role in the overall quality of modern building materials and construction projects, which can effectively improve construction efficiency and save investment cost, so as to prolong the construction period Service function and service life of buildings and structures.
