A reinforced cement concrete beam is considered to be made of

Concept:

Heterogeneous Material:

• Heterogeneous refers to a structure with dissimilar components or elements, appearing irregular or variegated. So, a heterogeneous material is a mixture of two or more materials.
• Concrete is a heterogeneous (Composite) material consisting of cement water, fine aggregates, and coarse aggregates. These are the ingredients of conventional concrete.
• Cement may be called a homogeneous material but concrete is not.
• Concrete's property is dependent on the individual properties of cement, sand, and coarse aggregates.
• The behavior alters greatly in a different direction due to a number of reasons.
• There are greater uncertainties in getting the same properties in all directions.

Note:

A material is said to be homogeneous when it is properties are the same in all directions. otherwise, it is a heterogeneous material.
