Static Segregation Column Mold For Self-Consolidating Concrete

The SCC Static Segregation Column Mold Test Set has everything you need to determine the potential segregation of coarse aggregate content in SCC mixtures in static condition.

The SCC Static Segregation Column Mold Test Set consists of 3 PVC plastic pipe sections, clamps and collector plate. Concrete sample is poured into the column and let set for 15 minutes. The collector plate is then held up to the level of the upper horizontal seam and the top portion is slid onto the collector plate. The material in the plate is then washed and the remaining aggregates are weighed. This is done for the other sections. The weights of the aggregates in the top, middle and bottom thirds are compared. If the weights are significantly different there is segregation in the concrete sample

Dimensions: 12 in x 12 in x 26 in LWH (305 x 305 x 660) mm.

Kit Contains: Segregation Tester Assembly, Collector Plate, and clamps.

SCC Static Segregation Column Mold Set

The Static Segregation Column Mold Set is a key tool for testing Self-Consolidating Concrete (SCC) mixtures. It measures the cohesiveness of SCC by evaluating the static segregation of normal weight coarse aggregate content in a concrete sample. The mold set consists of a cylindrical specimen, a base plate and 2 stainless steel collection plates with two sliding separator blades. The test involves pouring concrete sample the column  in the cylindrical specimen and letting it stand undisturbed for 15 minutes. After 15 minutes the top and bottom portions are evaluated for the amount of aggregate retained on a No. 4 (4.75 mm) sieve.

Segregation is calculated based on the top and bottom portions and the coarse aggregate content

Testing Procedure and Applications

Test procedure:

1. Prepare the concrete sample according to ASTM C1610/1610M.

2. Pour the concrete sample into the column and let it stand undisturbed for 15 minutes.

3. Evaluate the top and bottom sections for the amount of aggregate retained on a No. 4 (4.75 mm) sieve.

4. Calculate the segregation based on the top and bottom sections with the two sliding separator blades

The SCC Static Segregation Column Mold Set is used in:

• Fresh and Hardened Concrete Testing

• Self-Consolidating Concrete Sample

• Concrete Sample Mixture Pre-Qualification

• Deep section applications, walls and columns

Why Segregation Testing is important in SCC

Segregation testing is important in SCC mixtures as it can affect the quality and performance of the concrete. Coarse aggregate segregation can reduce flowability and block the passage during placement in vertical columns and wall sections. Voids and flaws can occur if the concrete can’t flow around the reinforcement and into the restricted formwork. So it’s important to evaluate the segregation of coarse aggregate in SCC mixtures to verify the quality and performance of the concrete.

Use the SCC Static Segregation Column Mold Set to test SCC mixtures, get accurate results and identify segregation issues. Verify SCC mixtures and prevent problems in deep section applications.
