Reinforced Concrete

List the primary components of concrete.
- Coarse/Fine Aggregate
- Water
- Cement
- Admixtures
- Entrapped/Entrained Air
Discuss Entrapped Air

Entrapped air are big bubbles of air and are non uniform
Discuss Entrained Air

Uniformly distributed air bubbles
Density of Normal Weight Concrete

145 pcf = 150 pcf
Why is the ratio of water to cement critical?

As the water to cement ratio increases: the workability increases and the strength decreases
Discuss aggregate in terms of a component of concrete
- We would like aggregate to "control" the strength
- 70-75% of mix by volume
What factors affect compressive strength?
- Water to cement ratio
- Aggregate
- Percent Air
- Placement Quality
- Curing
- Test Method
Discuss the short term behavior of concrete in uniaxial compression
Discuss the short term behavior of concrete in biaxial compression
Discuss the long term behavior of concrete in uniaxial compression
Modulus of Elasticity
