The grinding mill production line, large-scale development and application in our country, to the development of cement and concrete industries play an important role.Grinding mill added to save a large amount of cement and fine aggregate in concrete, concrete to increase modification, enhance sexual impact resistant ability to improve, frost resistance, etc.

 

At present, the powder into the cement in concrete and mineral admixture, if add lime stone powder, some people think that should be called powder.So not only has water cement ratio, water/cement ratio, also appeared a gouache than.Here is active.With everyone's subconscious gelled material quality and the basis of a definition or activity.

 

Actually in the chemical additive technology has considerable progress today, the powder in concrete should be more important?My understanding is: the water requirement of fine behavior, reasonable powder particle size distribution, satisfy the requirement of concrete strength of concrete were active, to prompt is high in the early activity admixture is not universal need, in many cases may be the opposite.

 

With a low water/cement ratio, low dosage of cement, low water consumption per unit volume as the main technical characteristics of modern concrete, It is the development direction of modern concrete technology.On this new technology platform, need hydration products fill the gaps in concrete has been greatly reduced.Achieve the same concrete strength, the gel decreased the number of requirements.So low activity powder is likely to get good technical effect in concrete.

 

Currently in the infrastructure construction in our country, the construction scale is huge, as the main body in the form of reinforced concrete structure, building structure of cement and concrete consumption accounts for over 55% of the world total.IT Is made of grinding mill production line processing of fly ash with high quality and high efficiency water reducing agent of composite technology in the production of high grade concrete in modern concrete technology is developing rapidly in the country.
