Properties of concrete - Wikipedia

Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.

What is Workability of Concrete? - Gilson Co.

Water to a cementitious material ratio (w/cm) of 0.45 to 0.6 is the sweet spot for the production of workable concrete. Aggregate Size and Shape: As aggregate surface area increases, more cement paste is needed to cover the entire surface of aggregates. So mixes with smaller aggregates are less workable compared to larger size aggregates.
