When you insert your hand into the cement bag, it should feel cool. Cement should settle down when dropped in a bucket of water; it shouldn’t float on water surface. The cement should feel smooth when touched. If it feels rough, it indicates adulteration of the cement. Colour of cement doesn’t affect its strength. It depends on the raw material used while manufacturing.
