Concrete is hard primarily due to the chemical reaction called hydration that occurs when water is mixed with cement. During this process, the cement reacts with water to form calcium silicate hydrates, which bond together and create a solid mass. Additionally, the aggregates (sand, gravel, or crushed stone) in the mix provide structural support and enhance the hardness. Once fully cured, concrete exhibits high compressive strength, making it durable and resistant to various stresses.

Why cement can hard?
Concrete has Portland cement in it. Portland cement is finely ground limestone that is baked until there is no water in it at all. After concrete is poured, the water in it starts chemically combining with the Portland cement, slowly turning it back into limestone . . . sort of. After 3 days, the concrete is hard enough to use . . . walking on or driving on with a light car, but it takes 28 days for concrete to harden to its full rated strength so it is usable in building, bridges, and so on.
