Calcium Stearate

• Calcium Stearate is a fatty acid salt often used as a concrete admixture additive to improve the properties of concrete. Using Calcium Stearate in concrete admixture additives can lead to many benefits, including improved workability, reduced water absorption, increased strength, cost-effectiveness, and improved finishing.

  Here are some ways in which calcium stearate can assist and change the properties of concrete:

  • Improved workability: Calcium Stearate is a lubricant in the concrete mix, making it easier to work with and allowing for better flow and compaction. This can be particularly useful when the concrete needs to be pumped or placed in hard-to-reach areas.
  • Reduced water absorption: Calcium Stearate can also help reduce the amount of water absorbed by the concrete, leading to better durability and a longer lifespan for the concrete.
  • Increased strength: Calcium Stearate can act as a water-reducing agent in the concrete mix, increasing strength and a lower water-to-cement ratio. This can result in denser, stronger concrete with fewer cracks and better resistance to weathering and other environmental factors.
  • Improved finishing: Calcium Stearate can also help improve the concrete surface’s finishing, resulting in a smoother and more uniform finish.
  • Release agent: Calcium Stearate can produce precast concrete products, such as blocks and pavers, to prevent concrete from sticking to the forms and molds.
  • Curing agent: Calcium Stearate can also be added to the concrete mixture as a curing agent to help reduce water evaporation and maintain the moisture in the concrete in the early stage of hardening.
