Performance of Lignosulfonates in Mortars

Demonstrations at our mortar laboratory show the water reduction achieved with Borresperse® CA at different dosage levels. We used a typical European standard mortar for the tests.

Using Borresperse CA as water reducer in mortar can influence all parameters: initial flow, workability, setting time and compressive strength development. The effect depends on the dosage. A typical range is 0.1 to 0.5% solids by weight of cement (sbwc).

Key takeaways:

  • 25% water reduction achievable
  • A cost-effective alternative to synthetic products
