There are many factors that affect the water demand of cement, and the restriction of the grinding process is one of them. In other words, the water requirements of cement produced by different grinding processes are different. If the efficiency of the grinding system is to be improved, no matter what more advanced grinding process we adopt, we must consider this Whether the water requirement of the process cement is appropriate. Otherwise, we must find a balance between grinding efficiency, grinding cost and water demand.

Cement Water Demand   

Cement standard consistency water demand (hereinafter referred to as cement water demand). The accurate characteristic parameter should be the standard consistency water consumption of concrete, which refers to the mixing water required to make the cement paste reach a certain degree of plasticity and fluidity. It is used for cement an important indicator of performance.

The water requirement of cement directly affects the water-cement ratio of concrete, and then affects the strength, corrosion resistance, frost resistance, and durability of concrete, affects the amount of cement and admixtures used in concrete production, and affects the cost and benefit of users.

The greater the water consumption for the standard consistency of cement, the greater the water consumption for the cement paste to reach the standard consistency, the water consumption for the cement mortar to reach the specified fluidity, and the water consumption for the cement concrete to reach a certain slump. The greater the water-cement ratio of mortar and concrete, the more voids between the particles and the smaller the density, which makes the construction performance, mechanical properties and durability of cement and concrete worse.

Intuitively, the concrete formula design has three basic parameters: water-cement ratio, water consumption, and sand ratio.

Reducing the water requirement for the standard consistency of cement is of great significance to the concrete industry to reduce the water consumption per cubic meter of concrete, thereby increasing its strength, reducing the amount of cement, and saving the cost of concrete production.

One is the influence of cement specific surface area, particle gradation, and particle shape.

The second is the influence of the type and amount of cement admixture.

The third is the influence of gypsum on the water demand of cement.

The fourth is the impact of clinker on cement water demand.

Fifth, the impact of grinding process on water demand.
