Description

FOSROC Conplast SP430 G8 is a high-range, water-reducing and retarding superplasticiser—an advanced liquid admixture based on sulphonated naphthalene polymers. It delivers up to 25% water reduction for improved workability without compromising strength. Ideal for pumpable, high-grade concrete (M30+), it enhances early strength, reduces permeability for greater durability, and improves cohesion for easier placement and compaction. It’s chloride-free, safe for reinforced and prestressed concrete, and conforms to ASTM C494 (Type A/G), IS 9103, and BS 5075 standards. Typical dosage: 0.5–2 L per 100 kg cement.
