Concrete Cube Mould Price in Bangladesh – Buy Genuine Cast Iron Cube Boxes

The concrete cube mould price in Bangladesh reflects a small but critical piece of testing equipment, and astzbd.com stocks a genuine 150x150x150mm cast iron cube mould available in both blue and black finishes. If your work depends on accurate compressive strength results, the wrong cube mould — one with warped walls or inconsistent internal dimensions — can quietly throw off an entire batch of test data before you even reach the compression testing machine.

Concrete Cube Mould 150x150x150mm – Full Specification

Concrete Cube Mould Overview – Standard Testing Equipment for Compressive Strength

A concrete cube mould shapes fresh concrete into a standardized specimen that, once cured, gets tested for compressive strength — one of the most fundamental quality checks in civil engineering and construction. This particular cube mould follows the widely used 150mm standard size, giving you a specimen format accepted across most testing standards and lab equipment configurations used in Bangladesh.

What Is a Cube Mould Used For in Concrete Testing?

Compressive Strength Testing Standards (ASTM, BS, IS Compliance)

Concrete cube moulds are built to match dimensional tolerances required by testing standards like ASTM, BS, and IS, ensuring the cast specimen’s shape doesn’t introduce measurement error when it’s later crushed under a compression testing machine.

Why 150mm Is the Standard Cube Size

The 150mm cube has become the default specimen size for most construction-grade concrete testing because it balances practical handling with a large enough surface area to give representative strength results, unlike smaller specimens that can be more sensitive to aggregate size variation.

Types of Cube Moulds We Offer

Cast Iron Cube Mould

The Concrete Cube Mould 150x150x150mm uses cast iron construction, offering the rigidity needed to hold its shape through repeated casting cycles without warping under load.

Steel Cube Mould

Steel variants trade some weight for added corrosion resistance, though cast iron remains the more common choice for standard compressive strength testing due to its proven dimensional stability.

Blue vs Black Color Variants

Both the blue and black finishes on our 150mm cube mould offer identical performance — the color choice comes down to lab preference or matching existing equipment, with no difference in testing accuracy.

100mm vs 150mm vs 200mm Cube Mould Sizes

If your testing protocol calls for smaller specimens or multiple simultaneous casts, the Concrete Test 3-Gang Cube Mould 50mm x 50mm lets you cast three 50mm cubes in a single mould, which is useful for mortar testing or situations where the standard 150mm cube isn’t the required specification.

Key Features to Look for in a Cube Box for Concrete

Material Thickness & Rigidity

A properly cast iron cube box resists flexing during compaction, which matters because any deformation during casting directly affects the final specimen’s dimensional accuracy.

Dimensional Accuracy (±0.2mm Tolerance)

Tight manufacturing tolerances keep each internal face true to 150mm, since even small deviations compound into meaningful errors when calculating compressive strength from cross-sectional area.

Detachable Base Plate Design

A removable base plate simplifies both cleaning between casts and demoulding the cured specimen without risking damage to the cube’s edges.

Smooth Internal Surface for Easy Demoulding

A properly finished internal surface reduces the concrete’s tendency to stick to mould walls, making demoulding faster and protecting the cube’s sharp edges from chipping.

Corrosion Resistance & Coating

A quality protective coating extends the mould’s usable life significantly, especially in humid storage conditions common across construction sites in Bangladesh.

Why Dimensional Accuracy Matters in Cube Mould Testing

Compressive strength is calculated by dividing the load at failure by the specimen’s cross-sectional area, so even a small dimensional error in the cube mould skews that calculation before the test even begins. This is exactly why the concrete cube mould price in Bangladesh for a genuine, precisely manufactured unit is worth paying over a cheaper, less accurate alternative — a warped or undersized mould can silently invalidate weeks of quality control data.

Cast Iron vs Steel Cube Mould – Which One to Buy?

For most standard construction and RMC quality control work, a cast iron cube mould remains the reliable, cost-effective choice. If your storage conditions are particularly harsh or corrosion is a recurring problem, a steel option may justify the added cost.

Concrete Cube Mould Price in Bangladesh

The concrete cube mould price in Bangladesh for the 150x150x150mm cast iron model is available at astzbd.com — contact astzbd.com directly for current pricing and stock availability in blue or black.

What Affects the Price (Material, Size, Thickness, Brand)

Material choice is the primary price driver — cast iron typically costs less than steel at the same dimensional accuracy, while wall thickness and manufacturing tolerance also factor into cost. Smaller multi-cavity moulds, like the 3-gang 50mm version, are priced differently based on their compact, multi-specimen design rather than single-cube volume.

Why Buy Genuine Cube Moulds from astzbd.com

astzbd.com stocks genuine cube moulds with verified dimensional accuracy, protecting your lab or site from unverified alternatives that can produce inconsistent, non-compliant test specimens.

Who Should Buy a Concrete Cube Mould?

Civil Engineers & Construction Site Supervisors

Routine compressive strength verification during construction phases depends on cube moulds that consistently produce standard-compliant specimens.

RMC (Ready-Mix Concrete) Plant Quality Control Teams

Batch-to-batch quality checks require reliable, repeatable mould dimensions to maintain consistent strength documentation across production runs.

University & Civil Engineering Labs

Teaching labs benefit from durable cube moulds that withstand frequent student use without losing dimensional accuracy over time.

Government Testing & Certification Bodies

Official compliance testing demands cube moulds that meet recognized dimensional standards, since specimen accuracy directly affects certification validity.

How to Use a Concrete Cube Mould – Casting & Curing Guide

1. Clean the mould thoroughly and apply a light coat of mould oil to the internal surfaces
2. Assemble the mould securely, ensuring the base plate is properly seated
3. Pour concrete in layers, compacting each layer to remove air voids
4. Strike off the top surface level with the mould edge
5. Allow initial curing for 24 hours before demoulding
6. Cure the demoulded cube in a water tank for the required testing period (typically 7 or 28 days)

Cube Mould Maintenance & Care Tips

Clean the mould immediately after each use to prevent cured concrete residue from building up on internal surfaces, apply mould oil before every casting cycle to ease demoulding, and store the mould in a dry area to prevent corrosion. Periodically check internal dimensions against a reference standard, since repeated use and cleaning can gradually affect surface accuracy over time.

Concrete Cube Mould FAQ

What size cube mould is used for standard concrete testing?

The 150mm cube mould is the most widely used size for standard concrete compressive strength testing, though smaller sizes like 100mm or specialized formats like the 3-gang 50mm mould are used for specific applications.

What is the difference between cast iron and steel cube moulds?

Cast iron moulds offer excellent rigidity and dimensional stability at a generally lower cost, while steel moulds provide better corrosion resistance, making them preferable in more humid or harsh storage environments.

How do I properly demould a concrete test cube?

After the initial curing period (typically 24 hours), carefully remove the base plate and side panels, applying gentle, even pressure to avoid chipping the cube’s edges before it’s fully cured.

What standard does a 150mm cube mould follow?

A properly manufactured 150mm cube mould meets dimensional tolerances compatible with ASTM, BS, and IS testing standards, ensuring specimens are accepted for standard compressive strength evaluation.

How long does a cast iron cube mould last with proper care?

With regular cleaning, proper mould oil application, and dry storage, a cast iron cube mould can remain accurate and functional for several years of repeated use.
