Aggregates are materials mixed with cement and water to create concrete. They come in various types, each serving specific purposes based on their characteristics. Here are some common types of aggregates:
1. Fine Aggregates:
- Sand: Natural or manufactured sand used to fill voids and create a smooth surface.
- Crushed Stone Dust: Smaller particles of crushed stone.
2. Coarse Aggregates:
- Gravel: Rounded particles often used for their smooth texture.
- Crushed Stone: Angular particles created by crushing rocks.

tension and compression play crucial roles in its structural integrity:
• Compression: Concrete is inherently strong in compression. This means it can withstand significant compressive forces without failing. When a load is applied to a concrete structure, the concrete primarily handles the compressive stresses.
• Tension: Concrete, however, is weak in tension. It tends to crack and fail under tensile stresses. To counteract this, steel reinforcement (rebar) is embedded within the concrete. Steel is strong in tension, so it absorbs the tensile forces that the concrete cannot handle
