Applications of Polyaluminum Chloride Coagulant in the Cement Industry

Polyaluminum chloride coagulant is an efficient water treatment coagulant that also has extensive applications in the cement industry. Cement is one of the important materials in the construction field today. However, the setting and hardening time of most cement products is currently too long, which can adversely affect the construction progress. Polyaluminum chloride coagulant can be helpful in this regard. The following is a brief analysis of the applications of polyaluminum chloride coagulant in the cement industry.

Polyaluminum chloride coagulant used as a concrete accelerator

After adding polyaluminum chloride coagulant to concrete, the principal components sodium aluminate and sodium carbonate react quickly with the gypsum in the cement in an alkaline solution to form sodium sulfate, causing the original retarding effect of gypsum to be lost. This accelerates the hydration of calcium aluminate minerals, and the crystallization of their hydration products precipitates in the solution, thereby causing the cement concrete to set quickly.

Polyaluminum chloride coagulant used in cement mortar

Polyaluminum chloride coagulant can increase the bonding force between cement particles, thereby enhancing the strength and hardness of cement mortar. In addition, Polyaluminum Chloride Coagulant can adsorb and remove moisture in the cement mortar, preventing the effect of moisture on the hardening process. It also promotes the coagulation of colloidal particles, improving the crack resistance and durability of the cement mortar.

Application Scenarios

• When building walls or applying waterproof materials, first mix Polyaluminum Chloride Coagulant with water into a paste, then add it to the cement mortar to improve the bonding strength and crack resistance of the mortar.

• For pavements requiring high strength and wear resistance, concrete containing Polyaluminum Chloride Coagulant can be used to create the pavement base layer.
  

• In underground projects or tunnels, Polyaluminum Chloride Coagulant is also used to make waterproof coatings to prevent groundwater infiltration.

Summary

Polyaluminum chloride coagulant is widely used in the cement industry in the processes of making concrete accelerators and cement mortar. It can significantly enhance the setting and hardening speed of concrete and improve the construction efficiency and quality of cement mortar.
