Nowadays, admixtures are one of the indispensable and important components of concrete. After a large number of repeated practices, it has been proven that they greatly improve the workability and slump of cement mixtures. Therefore, they are very important for improving concrete in actual industry. Performance plays a huge role. Especially in the past ten years, the concrete and admixture industries have undergone earth-shaking changes. When it comes to the development of concrete admixtures, it should be developed from three aspects. The first is the development around concrete; the first is the development of admixtures themselves; and the third is transformational development.
(1) Focus on the properties and uses of concrete, open up new application areas and improve admixture technology
It is necessary to focus on the properties and uses of concrete, especially open up new application areas to improve admixture technology Technology, currently domestic concrete production capacity is severely overcapacity. Where concrete is going to develop, cement is going to develop. The old path can no longer continue, and the development method must be changed. Therefore, concrete and cement must develop toward high-end, specialization, and special uses, toward use conditions in different environments and fields, and toward offshore engineering and special concealed engineering uses. The development to high-end is not the development in the past, and it must be addressed with the question of how admixtures can more effectively improve the durability, durability, and stability of concrete. According to the development of concrete, we should improve, because the field of concrete must have new expansion. Not only concrete in the construction field, but also concrete applications need to be developed in engineering, bridges, oceans, special environments, and various new uses. In order for admixtures to be suitable for various new uses, they must first play a role in performance. How to prepare and adjust them, how to make reasonable formulas and parameters, must be studied and improved with the development of concrete.
(2) The development of admixtures themselves
When it comes to the development of concrete admixtures themselves, we should start from three points. The first is to follow the continuous research and evolution of concrete marking, performance, use, grading and preparation to find the best combination point to ensure the stability and durability of concrete performance and the service life can be longer and longer. This aspect may need to be further Research and improve. Second, the quality assurance of the properties, processing and testing of various raw materials must be further improved so that the quality of the raw materials can be guaranteed first. There may still be a lot of work to do in terms of raw materials. Third, the process and equipment technology for manufacturing the admixture itself must also be improved, which cannot meet the existing technology, because we are developing around concrete. If concrete needs to develop and improve, our admixtures must also improve and develop.
(3) Transformation and Development
The previous development of admixtures followed the development of concrete, and concrete followed the development of building concrete or traffic concrete, bridge concrete, and offshore concrete. The next step is for concrete to transform into a decorative material and replace other materials. Its functions and performance are different. In the future, concrete can be used in decorative materials, beautifying the environment, and in different parts of buildings. The future development will be diversified and in many fields, so we must transform and develop. According to this new development, the entire Chinese building materials industry has long been developing at the mid- to low-end, and now it is moving to the high-end, developing into new fields, and opening up new territories. Then, there must be new products, especially in the development of concrete and cement. The development direction of cement is to increase the grade. However, without the function and participation of admixtures, if the cement grade is simply increased, the concrete will not achieve high performance. Therefore, admixtures have great potential here and there are many issues to be tackled. The technology should be improved and new goals should be continued to be developed.
Although concrete admixtures have made great progress, the development is still on the way. The road is far away, the prospects are bright, and the tasks are arduous.
