Know more about cube moulds for concrete testing

One of the most important devices that are used for concrete testing is cube mould. You can buy cube moulds online at affordable prices in order to do concrete testing.

How exactly is cube moulds used for concrete testing? It is quite a simple procedure. Concrete cubes need to be first made using the following equipment- Sample tray, a mould for making test cube, spanners, scoop, steel float or trowel, compacting bar, vibrating hammer or vibrating table, Cleaning rags, a bucket or barrow for the transportation of the samples, polythene sheeting, and curing tank.

Standard procedures have to be followed during the making, curing and testing of cubes. Even the smallest of deviations often have huge impacts, so great care has to be taken by the user.

After the remixing of the concrete, the cube mould is used. The cube moulds need to be filled and the concrete then compacted. This can be either done by hand or with the aid of vibration. If there is any air trapped in the concrete, it will end up with the reduction of strength of the cube.

Hence, it is important to fully compact the cubes. Care needs to be taken that the cubes are not over compacted. If they are over compacted there might be a segregation of the aggregates and the cement paste. That might reduce the final compressive strength.

Certain precautionary rules need to be followed during the making of cubes. In case the mould is too full, scraping off the top surface should not be done. This is because that could lead to the removal of the cement paste that has come to the top, leaving the concrete short of cement.

The correct method to do it is using a corner of the trowel and then digging out a fair sample off the concrete as a whole. The surface can then be finished off by trowelling. After you finish compacting the cement, do not let it stand on the same bench as another specimen that is being compacted.

This is in order to prevent the passing on vibrations to the first specimen which might lead to faulty compacting. In some extreme cases, this may cause segregation due to the re-arranging of some of the particles.

It is important to use good quality cube moulds for these purposes. If you are unsure of where to obtain these cube moulds from, you can consider getting them from online stores.
