Slump Test Apparatus

High-Quality Slump Test Apparatus by SV Technocrats India

A slump test apparatus is a vital testing tool used by site engineers to determine the workability and consistency of fresh concrete. At SV Technocrats India in Pune, we manufacture premium testing equipment that allows precise measurement of concrete settlement. Consequently, our apparatus helps civil engineers assess whether a concrete mix maintains the ideal moisture level for structural pouring.

Essential Components of the Slump Test Apparatus

Our testing apparatus includes durable, standardized components designed for field reliability:

• Slump Cone (Abrams Cone): A robust frustum-shaped metallic mold measuring 300 mm in height, 200 mm at the bottom diameter, and 100 mm at the top diameter.

• Standard Tamping Rod: A 600 mm long steel rod with a 16 mm diameter, designed for uniform concrete compaction.

• Rigid Base Plate: A smooth, non-absorbent metallic plate providing a level surface for accurate field testing.

• Precision Measuring Scale: Included to measure the exact vertical settlement of concrete after cone removal.

Step-by-Step Testing Procedure

To achieve accurate workability measurements, quality inspectors perform the standard testing procedure using a slump test apparatus:

1. Setup and Placement: First, place the metallic cone firmly on the smooth base plate.

2. Filling in Layers: Next, fill the cone with fresh concrete in three equal vertical layers.

3. Compaction: Then, tamp each layer 25 times using the standard steel tamping rod.

4. Cone Removal: Lift the cone smoothly in a vertical direction within 5 to 10 seconds.

5. Slump Measurement: Finally, measure the vertical settlement difference between the cone top and the concrete sample.

Common Types of Slump Results

• True Slump: The concrete stays intact and settles evenly, demonstrating excellent workability and cohesion.

• Shear Slump: The top portion slides sideways, indicating a harsh or poorly proportioned mix.

• Collapse Slump: The concrete collapses completely, revealing excess water content.

Practical Site Applications

• Mix Optimization: Ensures proper workability before placing concrete on job sites.

• Quality Assurance: Verifies the water-cement ratio for road and building construction.
