The first reaction is Prevention is better than cure- The failure of the Cube test depends upon the various aspect even the way it has been tested is also important.

When the cone is lifted from the concrete the distance between the top of the cone and the top of the subsided concrete is known as the slump. This is measured by subjecting. Due to this fact it has been widely used for workability tests since 1922.

The sample must be a good cohesive mix it may require some mixing once taken from the concrete batch to be suitable for a slump test and cubes. We are a full service supply company offering sales calibration and repair services. Initial and final setting time test.

The flow is measured in accordance with BS EN 12350-5. This is verified by laboratory testing such as performing cube tests to verify compressive strength flexural tests and supplemented by field testing such as slump tests done on site to verify plasticity of the mix. It is carried out conveniently as a control test and gives an indication of the uniformity of concrete from batch to batch.

Concrete can be mixed either by hand or by laboratory batch mixer. For concrete curing there is an array of curing boxes and all the equipment to set up your curing lab including the moisture room control system spray heads recording thermometers and tank heaters.
