Sikament®-686 is a high range water reducing admixture utilizing Sika’s ViscoCrete® Technology. It’s unique formulation is based on polycarboxylate technology. Sikament®-686 meets the requirements for ASTM C-494 Types A and F admixture.
- Higher early and ultimate strengths for cost effective high strength concrete and earlier structural use of concrete.
- Higher early strengths allow faster demolding and more efficient use of forms to precast producers.
- Increased slump improves workability and reduces labor costs.
- Full flow action aids in pumping and reduces need for vibration.
- Greater concrete density reduces permeability and increases durability.
