AZA 1107 COMPACTION FACTOR APPARATUS

Description

AZA 1107 COMPACTION FACTOR APPARATUS – Precision Concrete Workability Tester

The AZA 1107 Compaction Factor Apparatus from Azalab is specifically designed to determine the workability of low-slump concrete mixes that cannot be accurately tested using the standard slump cone method. As per IS and British standards, this apparatus is a crucial part of concrete testing labs, construction sites, and R&D centers.

This test provides a quantitative measure of the compaction factor—the ratio of the weight of partially compacted concrete to fully compacted concrete. It is especially beneficial for very dry mixes used in road construction or precast concrete elements.compaction factor apparatus, AZA 1107, concrete test equipment, low workability concrete tester, compaction factor test.

🔧 How It Works

The AZA 1107 apparatus comprises two conical hoppers mounted above a cylindrical receiver. The test involves allowing concrete to fall freely from the top hopper to the lower hopper and then to the cylindrical container. The difference in weight between partially and fully compacted concrete determines the compaction factor.

🧪 Testing Procedure

1. Fill the upper hopper with fresh concrete and level it off.

2. Open the trap door to allow the mix to fall into the lower hopper.

3. Immediately open the lower hopper to drop the concrete into the cylindrical container.

4. Weigh the concrete in the cylinder (partially compacted weight).

5. Refill the cylinder in layers, fully compacting each layer.

6. Weigh again (fully compacted weight).

7. Ideal for precast yards, construction sites, and testing labs

8. More accurate than slump test for dry concrete

9. Compaction Factor = Partially Compacted Weight / Fully Compacted Weight

This gives a value between 0.7 and 0.95 for typical mixes, providing a direct measure of concrete’s workability.

❓ Frequently Asked Questions (FAQ)

Q1: What is the use of a compaction factor apparatus?
A: It helps determine the workability of very low-slump concrete mixes that are not suitable for a slump cone test.

Q2: Is this test more accurate than slump testing?
A: Yes, especially for dry or stiff mixes. Slump testing isn’t reliable for such concretes.

Q3: What standards does the AZA 1107 comply with?
A: It complies with IS 1199 and BS 1881 Part 103.

Q4: Who should use this equipment?
A: Civil engineers, construction QC personnel, and lab technicians working with concrete mixes.

Q5: Is this apparatus portable?
A: While it’s not handheld, it can be easily transported and set up at different job sites.
