The ability to improve the workability of concrete without affecting other properties and without increasing costs is the performance of high technical level and rich working experience. What is good workability is not so easy to describe in words, it is a feeling, the kind of appearance level that is the feeling of performance.
If the water reduction rate is compared to the performance of the strength of the car's power, the workability is the parameters of the brake and the airbag, that is, everything is important but not always needed. The workability of concrete is a complex systematic expression. At the beginning of the development of China's concrete industry, the amount of adhesive material across the country is conservative, and the natural sand resources are rich, making the workability of concrete generally good. In recent years, the mechanical sand to replace the increasingly strained natural sand, reduce the amount of rubber to achieve the purpose of energy conservation and emission reduction trend, the workability of concrete has become more and more important.
