CONCRETE AS A CONSTRUCTION
MATERIAL
TOPIC 2. CONCRETE AS A CONSTRUCTION MATERIAL
Concrete has components:
1. BINDER (CEMENT) – combined with water to create a paste. This paste-like substance dries and sets/
hardens.
2. CONCRETE AGGREGATES (SAND AND GRAVEL) – grain skeleton of concrete.
3. ADMIXTURES (LIQUIDS AND POWDERS) – have a significant effect to the properties of concrete.

CONCRETE PSI METHOD (POUNDS PER SQUARE INCH)
o
This is the method that allows us to measure the compressive strength of concrete.
o
Higher PSI = concrete is stronger, more expensive, more durable
o
IDEAL PSI (highly dependent on structure and other factors) – 2,500 to 3,000 PSI.
o
How is PSI tested? It takes 7 days and then 28 days to determine the psi of concrete.
CONCRETE (cement) CAN BE USED IN THE FOLLOWING:
✓ Pavements
✓ Architectural structures
✓ Foundations
✓ Motorways
✓ Roads and bridges
✓ Overpasses
✓ Parking structures
✓ Walls and footings
✓ Fences and poles
