Concrete is widely used in civil engineering and construction. Concrete admixture is a kind of decorative material, which is characterized by impermeability, small dosage, large function and wide application. The admixture greatly improves the performance of ordinary concrete, makes concrete more widely used, and has good social and economic value. More importantly, with the development of science and technology, people's vision is also improving, which requires concrete admixture has better performance and more complete function.

In the concrete mixing process or before the addition of concrete hardening and better mixing of materials known as concrete admixture, admixture impermeable, dosage is small, the role of large. Its important role is mainly reflected in the following two points: the performance of silt concrete has been greatly improved, which is conducive to the technological revolution of construction. There are many kinds of additives, and they have different functions. In today's increasingly serious environmental problems, the role of concrete in environmental protection is more obvious. The application of admixtures in concrete can promote the utilization of industrial by-products while reducing the amount of cement.

At present, China is in large-scale infrastructure construction, the amount of concrete is very large. Moreover, concrete admixtures have become an important component to improve the performance of concrete, which is conducive to ensuring the durability and service life of the project. Therefore, our country urgently needs to improve the technical level of concrete construction. Nationwide, the amount of admixture concrete only accounts for the total amount of concrete40%, far behind the developed countries, indicating that concrete admixture still has a lot of room for development.

After the market competition in recent years, it has highlighted a number of additive manufacturers with high level, large production scale and perfect after-sales service. These companies occupy a large market, especially in the synthetic additives market, dominated by large brands. Their products sell well all over the country, while small-scale enterprises play a role in supplementing the market. The starting point of the production line of large enterprises is relatively high, which has changed the original old production mode and has perfect inspection equipment and management.

The production and use of additives in China are not balanced in various regions, and additives are widely used in economically developed areas. For example, additives are widely used in some big cities in China and some cities in the eastern region, but less in the western cities. The yield of high-efficiency water reducing agent is increased, and new varieties of high-efficiency water reducing agent are also put into production and use. However, the proportion of new varieties is small, and some production technologies need to be further improved.

The development level of concrete admixture reflects the national standard product of concrete technology, and is an indispensable new building material for high-quality projects in China. The admixture enterprises should strengthen technology research and development, develop new products, etc. Pay attention to product quality while increasing service awareness. In accordance with the policy of energy conservation and emission reduction, accelerate the deployment of cleaner production and safe production, achieve a win-win situation for society, environment and efficiency, develop towards scale and comprehensive utilization of resources, realize the strategic adjustment of the admixture industry, and provide the country with high-quality materials.
