  1. Strength of concrete shall depend to a great extent on the voids in it.
  2. As such to have lesser voids so as to get stronger concrete the aggregates should be well graded i.e., they should have particles of various sizes so that the voids of bigger particles are filled up by the particles of smaller sizes.

Type I is used for most residential work Type II is used in moderate sulfate conditions Type III is used in climates where freezing is a risk Type IV is used for special orders like industrial placements Type V is used in extreme sulfate conditions

Types I and II are the most widely used residentially in the United States due to the relatively moderate climates we experience here.
