These cement and concrete standards allow laboratories all over the world to test and evaluate concrete mixtures to ensure their strength and safety. These standards help to identify the various properties of concrete including strength, elasticity, hardness, and workability.
The fluidisation of concrete allows entrapped air to rise to the surface, and the concrete becomes denser. With a properly designed cohesive mix, segregation and bleeding will be minimised. With an over-wet mix, the larger aggregate pieces may settle during compaction, with the result that a weak layer of laitance will finish up on the surface; if this does happen, the laitance must be removed.
