Product Overview

Conplast SP337 is a lignosulphonate-based, mid-range water reducing plasticiser for structural concrete. It conforming to ASTM C494 Type A (water reducing) and Type D (water reducing and retarding at higher dosage), and IS 9103. Conplast SP337 provides a typical water reduction of 8 to 12% at standard dosage, which is less than a superplasticiser but sufficient for improving the workability of standard structural concrete mixes, reducing bleeding, and improving pumpability without requiring the additional cost of a high-range water reducer. It is widely used in India for standard structural concrete in multi-storey buildings, foundations, and infrastructure projects where the design strength requirements do not justify the cost of full superplasticiser dosage. Conplast SP337 is also used as a base plasticiser in combination with other admixtures — for example, with Conplast NC accelerator or with retarders for hot weather placing. It is compatible with all standard Portland cements and blended cements. Space Arc Engineering distributes Conplast SP337 for construction projects across Delhi NCR, Ghaziabad, and Northern India.

Applications

• Standard structural concrete (M20 to M35) in building construction
• Foundation and ground slab concrete plasticising
• In-situ structural concrete with improved pump ability
• Base plasticiser for multi-admixture concrete mix designs
• Reducing water-cement ratio in general concrete for improved durability
• Concrete for retaining walls and civil structures where M30 or below is specified
