150mm Concrete Testing Cube Mould @ Puchong

150 mm Square Concrete Test Cube Mould @ Puchong

Product Description:
Our 150 mm square concrete test cube moulds are designed for precision and durability in concrete testing laboratories. Manufactured from high-quality steel or polypropylene, these moulds ensure accurate and consistent cube dimensions for compressive strength testing. Their smooth internal surfaces facilitate easy de-moulding and minimize the risk of cube damage. Suitable for standard laboratory testing, these moulds conform to international standards for concrete cube testing.

Technical Specifications:

• Cube Size: 150 mm × 150 mm × 150 mm
• Material: High-grade steel (for long-term durability)
• Wall Thickness: 3 mm (steel)
• Finish: Smooth internal surface for easy de-moulding
• Standard Compliance: ASTM C109 / BS EN 12390-1
• Stackable Design: Yes, for efficient storage
• Weight: Approx. 3 kg per steel mould

How to Use a 150 mm Concrete Test Cube Mould

1. Clean the mould

• Make sure all surfaces (inside walls and base) are clean.
• Remove dried concrete, dust, and debris.

2. Apply mould oil / release agent

• Lightly brush or spray a thin coat of release oil on all internal surfaces.
• This prevents the concrete cube from sticking and makes demoulding easier.
• Do not apply too much — thin layer only.

3. Assemble and tighten the mould

• If your mould has removable sides or a baseplate, assemble it properly.
• Tighten bolts or clamps so there are no gaps or leaks.

4. Fill the mould with fresh concrete

• Concrete must be placed in 3 layers (for a 150 mm cube).
• Each layer should be approximately one-third of the mould height.

5. Compact each layer

Use a tamping rod or vibrating table:

If using tamping rod

• Rod each layer 35 times in a uniform distribution.
• Make sure to penetrate slightly into the layer below.

If using vibrating table

• Vibrate until no more air bubbles appear.
• Do NOT over-vibrate (can cause segregation).

6. Level the top

• After the final layer, use a trowel or straightedge to strike off the surface.
• Make the cube level and smooth.

7. Label the cube

Write on a tag or directly on the cube mould:

• Date
• Batch number
• Location (if site testing)
• Mix details

8. Cover the mould

• Cover the top with a plate, plastic sheet, or damp cloth.
• Prevent moisture loss — curing starts now.

9. Initial curing (24 hours)

• Keep the mould in a shaded area at 20–25°C if possible.
• Do not disturb it.
• Good curing = accurate strength results.

10. Demould after 24 ± 2 hours

• Loosen bolts/clamps.
• Remove the sides gently.
• Take the cube out carefully without damaging the edges.

11. Final curing in a water tank

• Place the cube in a curing tank at 20°C water until the test age:
• 7 days
• 28 days (standard)
• Or as required

12. Test the cube

• Test in a compression testing machine at the required age.
