Is concrete made of sedimentary rock?

Answer 1

The Portland cement used to bind the aggregate materials of concrete together is made primarily from cooked limestone, baked at high temperatures in giant tilted rotating drums. The aggregate rock can also be made from limestone.

Answer 2

Concrete is not made of sedimentary rock. Concrete is a mixture of cement, water, and aggregates such as sand and gravel. Sedimentary rocks are formed through the accumulation and solidification of sediment over time.
