Current status, development direction and future trends of concrete admixtures

With the improvement of modern construction levels, building structures have become more complex, the demand for concrete has continued to increase, and the requirements for concrete performance have also become higher. Admixtures are used to improve the properties of concrete. Therefore, the amount of additives required is also increasing, and the requirements are getting higher and higher. Therefore, future concrete admixtures will develop in the following aspects.

(1) Composite type. Compound admixtures can make up for their weaknesses in terms of efficacy and are constantly optimized. They also need to be low-priced, have a wide range of applications, and have excellent properties.

(2) The types are universal and diversified. To continue to develop new product varieties and make them more versatile and diversified, we must first consider the needs of various types of projects and facilitate project application and quality management.

(3) Develop high-strength admixtures. In recent years, the average strength and maximum strength of commonly used concrete have continued to increase. The development of high-efficiency admixtures for high reinforcement and aging resistance has provided standards for the production of high-strength and ultra-high-strength concrete, and the use of high-efficiency admixtures The water-reducing effect of the water-reducing agent can produce concrete with high fluidity, which saves effort in construction, reduces project costs, and improves labor efficiency.

(4) Reduce the cost of admixtures. Make full use of various industrial wastes to produce admixtures, and innovate the preparation methods and production processes of admixtures. Produce low-cost, high-quality and efficient types of admixtures to enhance market competitiveness for widespread application and promotion of concrete admixtures.

(5) Improvement, in-depth analysis of the efficacy principles of concrete admixtures. With the development of science and technology, advanced detection methods should be adopted to develop the functional principles of admixtures, so as to lay the foundation for further exerting the effect of admixtures, obtaining stronger economic benefits, and effectively guiding production.

Generally speaking, actively developing and applying and promoting concrete admixtures is an effective way to promote the development of scientific research in the construction industry. With the continuous development, design and improvement of concrete admixture types, the quality will be significantly improved, the application will become increasingly common, and the efficacy will continue to improve, which will bring greater economic benefits to the construction industry. Building levels will also rise to higher levels.
