Study Notes
Concrete Composition
- Concrete is a material that consists of cement, sand, and water.
Concrete Materials
- The materials used to make concrete are cement, sand, and water.
Reinforced Concrete
- The purpose of reinforcement in reinforced concrete is to add strength and durability.
Aggregates
- Aggregates in construction are inert materials that are mixed with cement to form concrete.
- Aggregates can be classified into two types: fine aggregate and coarse aggregate.
Aggregate Types
- Fine aggregate is a type of aggregate that is smaller in size, typically consisting of sand or crushed stone.
- Coarse aggregate is a type of aggregate that is larger in size, typically consisting of gravel or crushed rock.
Rebars
- Rebars are commonly made of carbon steel.
- Carbon steel bars used in construction are usually referred to as "mild steel bars".
- The primary purpose of rebars in construction is to provide additional strength and support to concrete structures.
