advantages and disadvantages of pre grinding process for making cement

Concrete has high strength in compression but is weak in tension. Since it is brittle in nature it may crack suddenly after failure. So, to make the concrete strong in tension and prevent the sudden collapse of the structure we have to provide tension-bearing materials like steel rods in the tension zone of the slab.
