Self Compacting Concrete Mix Design.

Our Services

Achieving Flowability, Density, and Durability Without Vibration

Self Compacting Concrete Mix Design (SCC) is a specialized process of proportioning cement, water, aggregates, and admixtures to produce a concrete that can flow and consolidate under its own weight — without external vibration. Unlike conventional concrete, SCC spreads effortlessly, fills formwork completely, and achieves perfect compaction even in congested reinforcement areas or intricate geometries. At Global Lab, our SCC mix designs comply with EFNARC Guidelines, IS 10262:2019, IS 456:2000, and ACI 237R, optimized through advanced material testing and trial batching. We ensure every SCC mix delivers the right balance of flowability, passing ability, and segregation resistance for its intended structural application.

Why SCCMatters.

To Achieve Superior Structural Quality in Complex Structures

SCC is indispensable for heavily reinforced elements, intricate architectural forms, and narrow gaps where vibrators cannot reach. The concrete flows freely and self-compacts, eliminating voids, honeycombing, and surface blemishes, resulting in higher structural integrity and superior finish quality.

To Improve Construction Efficiency and Reduce Costs

By removing the need for mechanical vibration, SCC drastically improves placement speed and reduces labor requirements. It enables faster construction cycles, quieter operation, and greater consistency in large-scale projects such as bridges, tunnels, and high-rise buildings, especially in urban or noise-sensitive areas.

To Enhance Durability and Longevity

SCC forms a dense, homogenous matrix with minimal voids, providing exceptional resistance to chloride penetration, carbonation, and water ingress. This makes it ideal for marine structures, industrial facilities, and parking decks, where durability and low permeability are critical for long-term performance.

To Improve Aesthetics and Surface Finish

SCC offers a smooth, defect-free finish — eliminating surface bug holes and inconsistencies. This makes it highly suitable for architectural concrete applications, facades, and precast components where appearance is as important as performance.
