Product Overview

Structuro 201 is a high-performance polycarboxylate ether (PCE) superplasticiser from Fosroc formulated for the production of self-compacting concrete (SCC) and very high workability structural concrete. Self-compacting concrete flows under its own weight to completely fill the formwork and surround the reinforcement without any mechanical vibration — a significant advantage for congested reinforcement, inaccessible areas, complex formwork shapes, and where vibration would disturb adjacent freshly placed concrete or sensitive structures. Producing true SCC requires more than high fluidity — the concrete must also resist segregation and bleeding even at the very high slump flow (typically 600 to 750 mm by flow table test) required for self-compaction. Structuro 201 provides the very high plasticising effect needed for SCC slump flow while the molecular architecture of the PCE polymer also imparts cohesion to the concrete paste, resisting the separation of the coarse aggregate from the mortar matrix that would occur if a conventional superplasticiser were used at high dosage. Structuro 201 is used in precast concrete plants for producing architectural concrete with high-quality surface finish, in cast-in-situ construction for congested reinforcement sections, and in any application where mechanical vibration is undesirable or impractical. The product must be used with an SCC mix design that includes appropriate powder content and aggregate grading — it is not possible to produce SCC simply by adding Structuro 201 to a conventional concrete mix. Space Arc Engineering distributes Structuro 201 for precast, architectural, and high-performance structural concrete projects across Delhi NCR and Northern India.

Applications

• Self-compacting concrete for precast elements with complex shapes and high-quality surface finish
• High-workability concrete for congested reinforcement in structural columns and shear walls
• Architectural concrete where surface quality and absence of vibration marks is required
• Under-slab grouting and base slab void filling using high-fluidity concrete
• Cast-in-situ concrete for areas inaccessible to conventional vibrators
• High-rise concrete wall and core concreting via concrete pump with high slump requirements

Key Advantages

• Specifically formulated for self-compacting concrete production
• Very high fluidity with resistance to segregation and bleeding
• PCE chemistry provides cohesive paste for SCC without VMA in many mixes
• Can eliminate mechanical vibration — reducing noise and plant requirements
• Enables high-quality surface finishes in precast and architectural concrete
• Compatible with fly ash, GGBS, and silica fume for SCC powder content
