Although the terms are often used interchangeably, with concrete sometimes being referred to as cement and vice-versa, this is incorrect. In reality, cement is only an ingredient found in concrete, whereas concrete is a mixture of various components and paste.
Concrete is a mixture composed of components like crushed stone or gravel and sand, which is combined with a paste consisting of cement and water. This makes concrete similar to mortar in terms of materials but tends to be more durable and stronger than mortar due to its added aggregates.
Concrete also features a lower cement-to-water ratio and is of a thinner consistency than mortar.
