Description
CHRYSO®HS 621 is a water reducing plasticizer based on modified sulfonated poly naphthalene. It acts on the cohesion of fresh concrete & Workability retention properties. The use of CHRYSO® HS 621 is particularly recommended for Jobsite concrete requiring homogenous concrete without any segregation & bleeding which should have stable workability with time. It also acts as integral water-proofer for concrete.
Domain of Application:
- All cement types Pumped Concrete
- Regular Reinforced Concrete
- Liquid retaining structures Slump Concrete
Benefits
CHRYSO®HS 621 produces cohesive concrete for jobsite application normally for grades of concrete between M20 to M40. CHRYSO®HS 621 will make concrete is denser with less capillary action. Depending on the dosage, workability will be 60 to 120 min and does not affect hydration of cement. CHRYSO® HS 621 is well compatible with most of the major Cement brands available in India. Reduction in concrete permeability protects against water migration & corrosion of embedded steel inside the concrete esp. important for liquid retaining structures. For the same concrete mix, keeping everything else constant, a definite economy in cement content, can be achieved.
