How do you cast concrete cubes

Question

Accepted Answer

Concrete cubes are cast by filling a cube-shaped mold with freshly mixed concrete and allowing it to cure.

Prepare the mold by cleaning and oiling it to prevent sticking.
Mix the concrete according to the desired strength and consistency.
Fill the mold with the concrete, making sure to compact it well and eliminate any air pockets.
Smooth the surface of the concrete and cover the mold with a plastic sheet to prevent moisture loss.
Allow the concrete to cure for at least 24 hours before removing the mold and testing the cube's strength.
Label the cube with the date, mix design, and other relevant information for future reference.
