Compressive strength test of concrete cube

Concrete Test Cube Moulds concrete cube dimensions Concrete cubes of size 15cm x 15cm x 15cm are typically used for the test The cubes are cured for 7 days or 28 days then tested in a compression testing cube testing format In this work on hollow sandcrete cubes, Okonkwo found that void 45° orientation have high strength values Strength calculation for hollow concrete units

sampling of concrete cubes as per is code Concrete cubes are typically made in moulds with dimensions of 150mm x 100mm x 150mm The moulds have to meet the British Standard for testing hardened concrete
