Concrete Test Moulds Two-part Plastic Cubes
In stock
Choose from 100mm or 150mm reusable concrete cube moulds. Available to purchase as one or in a pack of six.
The Qube™ plastic concrete test mould has a revolutionary design that caters for rapid debonding and multiple reuse. These lightweight (reduce postal cost) and comply with EN-12390-1 standards.
Used for: A concrete cube test involves taking a sample of freshly mixed concrete, letting it cure, then crushing it and measuring its compressive strength. Many concrete suppliers carry out this process at a certified test house, away from their facilities in a temperature-controlled state-of-the-art testing laboratory.
Hardened Concrete Compressive Strength Testing
To verify the strength of a freshly mixed concrete, cube samples are taken in either 100mm or 150mm cube moulds. Before their compressive strength can be tested, the cubes must be placed in a curing tank for 28 days. They are then placed into a compression machine, where they are subjected to increasing load until failure.
The resulting maximum load will be divided by the cross-sectional area of the sample to calculate its compressive strength. The compressive strength can then be compared to the design strength of the concrete mix. This is critical for determining if the mix can reliably withstand the weight and pressures of its intended use.
The Qube™ plastic concrete test mould is a revolutionary concrete test mould that allows for rapid forming and deforming of test cubes.
The innovative design is lightweight allowing for easy transportation and it's plastic construction is easy to de-bond from the cured concrete. Simply slide the corner grips and open the mould, remove the cube and replace the corner grips and the mould is ready to go again.
Unlike polystyrene moulds the Qube™ (manufactured from robust heavy duty Polyurethane) will give you multiple reuse. No more seized or stiff bolts to undo. No more back breaking lifting 15kg steel moulds plus the weight of the concrete. Simple, lightweight and cost effective. The plastic cube mould is far easier to use than traditional plastic moulds.
Aggregate size specifications
Cubes of 100mm size are not suitable for concrete having a nominal maximum aggregate size exceeding 20mm. Cubes of 150mm size are not suitable for concrete having a nominal maximum aggregate size exceeding 40mm.
