J Ring For Self Compacting Concrete

About J Ring For Self Compacting Concrete

A J Ring Apparatus is a specialized testing tool used to evaluate the passing ability and flow characteristics of self-compacting concrete (SCC). It is used in conjunction with the slump flow test to assess how well concrete can flow through obstructions such as reinforcement bars without segregation or blockage.

The apparatus consists of a circular ring fitted with vertical steel rods that simulate reinforcement, allowing accurate analysis of concrete performance in real construction conditions.

Key Features

• Designed for SCC passing ability testing
• Durable and robust steel construction
• Precisely spaced vertical rods for accurate simulation
• Corrosion-resistant finish
• Easy to handle, use, and maintain
• Compatible with standard slump cone tests

Technical Specifications (Typical)

• Material: Mild Steel / Stainless Steel
• Shape: Circular ring with vertical rods
