Introduction Slump Cone Test Apparatus

The Slump Cone Test Apparatus stands as one of the most fundamental tools in concrete quality control for construction projects across Bangladesh. Engineers and lab technicians use this Slump Cone Test Apparatus to evaluate the workability and consistency of fresh concrete before placement — a critical step that prevents structural failures caused by improper mix design. ASTZBD supplies this ASTM C143 and BDS-compliant apparatus at the most competitive price in Bangladesh,

• Key Features

  1. ASTM C143 and BS 1881 Compliant: This apparatus meets international standard dimensions — 300 mm height, 200 mm base diameter, 100 mm top diameter. Furthermore, it satisfies BDS requirements, so test results are valid for government and private project documentation in Bangladesh.
  2. 5mm Thick Mild Steel Body: The cone uses durable 1.5 mm galvanized mild steel throughout the body. The smooth internal surface prevents concrete adhesion and simplifies cleaning between tests, so technicians complete each test cycle faster.
  3. Complete Kit — Three Components: The set includes the slump cone mold, a 16 mm × 600 mm bullet-pointed tamping rod, and a non-porous flat steel base plate. Additionally, the kit requires no extra accessories — everything arrives ready to use straight from the box.
  4. Welded Foot Rests and Side Handles: Two welded foot rests hold the cone firmly on the base plate during the filling process. Two side handles allow the operator to lift the cone in a smooth, controlled vertical motion when performing the test.
  5. Corrosion-Resistant Surface Finish: A protective finish on the outer surface guards the steel against cement alkali and moisture. As a result, the apparatus maintains structural integrity and dimensional accuracy through years of heavy daily field use.
  6. Lightweight and Portable Design: The complete Slump Cone Test Apparatus weighs under 3 kg. Therefore, field technicians carry it to any point on a construction site and perform on-the-spot slump testing without delay or assistance.

 

 

• Applications

  1. Ready-Mix Concrete Plants: Quality control teams at RMC plants use the Slump Cone Test Apparatus on every batch to verify that the water-cement ratio and workability match the approved design mix before dispatch to the site.
  2. Building Construction Sites: Site engineers test each truck delivery of concrete on arrival. They use the apparatus to confirm that the mix stays within the acceptable slump range for columns, beams, slabs, and foundations.
  3. Civil Engineering Laboratories: Universities, polytechnic institutes, and private materials testing labs across Bangladesh use this apparatus for standard concrete workability practicals, research projects, and certification testing.
  4. Road and Infrastructure Projects: Contractors on bridge, culvert, highway, and retaining wall projects rely on regular slump testing to maintain concrete quality at every structural pour point throughout the project lifecycle.
  5. Precast Concrete Manufacturing: Precast concrete manufacturers run slump tests throughout production to control mix workability precisely, so each product batch meets dimensional and strength consistency requirements.
  6. Government and BNBC Compliance Projects: Projects under government inspection or BNBC approval requirements document slump test results as mandatory quality assurance evidence. Additionally, third-party inspection agencies use this apparatus to verify site compliance.

Frequently Asked Questions (FAQ)

1. What is a Slump Cone Test Apparatus and why does concrete testing need it?

A Slump Cone Test Apparatus measures the workability and consistency of fresh concrete by recording how much the concrete subsides after the mold lifts away. Engineers use this measurement to confirm the concrete mix meets the specified water-cement ratio and workability range before placement.

1. Which standards does this Slump Cone Test Apparatus comply with?

This apparatus complies with ASTM C143 / C143M, BS 1881: Part 102, and BDS standards. The critical dimensions — 300 mm height, 200 mm base diameter, 100 mm top diameter — match all three specifications exactly, so the results are universally accepted.

1. How do I perform the slump test correctly with this apparatus?

Place the cone on the base plate and stand on the foot rests. Fill the cone in three equal layers and tamp each layer 25 times with the rod. Strike the top surface level, then lift the cone vertically over 5–10 seconds. Finally, measure the slump as the height difference between the original cone height (300 mm) and the top of the slumped concrete.

1. What slump values indicate acceptable workability for different concrete types?

General structural concrete typically targets 25–75 mm slump, reinforced concrete 50–100 mm, and pumped or highly workable concrete 100–150 mm. Your structural engineer or design mix specification defines the exact acceptable range for each pour.

1. Does ASTZBD ship the Slump Cone Test Apparatus outside Dhaka?

Yes. ASTZBD ships to all districts across Bangladesh including Chittagong, Sylhet, Rajshahi, Khulna, Barishal, and Rangpur through trusted courier partners with full tracking.
