Aluminum Sulfate

• Aluminum Sulfate, also known as alum, is a white crystalline substance commonly used in various dry mix bagged products. Aluminum Sulfate is a widely used accelerator that can improve concrete’s setting and curing time. It is often used when a quick turnaround time is needed or when the weather is cold.

  When added to concrete, Aluminum Sulfate reacts with the Calcium Hydroxide in the cement paste to form Aluminum Hydroxide and Calcium Sulfate. This reaction can lead to the formation of denser and more durable concrete, which can be beneficial in situations where the concrete will be exposed to harsh conditions.

  Here are some examples of its applications:

  • Used as a setting accelerator in concrete mixes helps to speed up the hardening process, allowing the concrete to set more quickly and reach its full strength faster.
  • In Mortar mixes, Aluminum Sulfate helps control the setting time and improve the workability of the mixture and can also help improve the finished mortar’s strength and durability.
  • In Grout mixes, Aluminum Sulfate can be added to grout mixes to improve the water-resistance and overall strength of the grout.
  • In Self-Leveling Compounds, Aluminum Sulfate is often used as a setting accelerator that can help to speed up the curing process and ensure that the compound sets evenly.
  • In Tile adhesives, Aluminum Sulfate is used to improve the water resistance and overall strength of the bond. It can also help improve the mix’s workability and reduce the risk of cracking or shrinkage.
