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.
You need sand in it. 1 part cement to 2 parts sand.
