On looking, Cement should have a grey color with a light greenish shade.
It should feel smooth when rubbed between fingers. If the hand is inserted in heap cement or its bags, it should feel cool.
When a pinch of cement is thrown in Water then cement should float for some time before it sinks. Cement should be lump-free when checked by putting the hand in the mixture.

h. M35, M40 – Design Mix Followed
47. What are the tests used for checking brick quality?
Ans: Absorption test, Hardness Test, Shape & size test, crushing strength test, soundness test, etc. are performed to determine the brick quality. For example, in the water absorption test, brick is dipped in freshwater for 16 hours in water. And depending on the weight of brick its class is decided such as if the weight of brick after dipping in water doesn’t exceed 20% it can be considered as a first-class brick if below 22.5% it can be considered as second class brick, and so on.
