Product Overview

Auracast 405 is a polycarboxylate ether-based admixture system developed for producing self-compacting concrete (SCC) in architectural and structural applications where conventional vibrated concrete is difficult or impossible to compact properly. SCC produced with Auracast 405 has sufficient flow to fill complex formwork geometries and pass through congested reinforcement without vibration, while its viscosity modifying agent (VMA) prevents segregation and bleeding that would otherwise occur in such a fluid mix. Self-compacting concrete eliminates the principal cause of honeycombing and voids in concrete — inadequate compaction due to difficult access or improper vibration technique. For heavily reinforced columns, dense structural walls, pre-cast elements with complex profiles, and architectural concrete where the visual quality of the surface is critical, Auracast 405 SCC delivers a step change in concrete quality compared to conventional vibrated concrete. The system consists of a high-range PCE superplasticiser combined with a VMA in the correct proportions, and requires careful mix design trial and validation before site use. Space Arc Engineering distributes Auracast 405 for high-specification structural concrete projects across Delhi NCR, Ghaziabad, and Northern India.

Applications

• Heavily reinforced column concrete where vibration access is limited
• Dense wall concrete for uniform compaction without vibration
• Architectural exposed concrete elements where surface quality is critical
• Precast concrete production requiring complex shape filling without voids
• Foundation concrete in confined spaces where vibration is impractical
• High-rise building core wall concrete requiring SCC for productivity

Key Advantages

• Self-compacting — eliminates vibration and honeycombing risk
• PCE + VMA system provides controlled flow without segregation
• Improves concrete quality in heavily reinforced elements
• Suitable for complex formwork geometry that cannot be reached by vibrator
• Mix design flexibility for different aggregate types and cement combinations
• Enables high productivity concrete placing in tall walls and columns
