CONCRETE

CONCRETE

1. CONCRETE = AGGRGREGATE + CEMENT PASTE

   • Cement Paste = Cement + Water
     • Mortar = Cement Paste + fine aggregate
       • Concrete = Mortar + Coarse Aggregate
   • Composite Material where Aggregates = Reinforcement and Cement Paste = Matrix

2. 2 BILLION TONNES USED PER YEAR

3. ADVANTAGES

   • Economical
   • Ability to be cast
   • Low Energy demand compared to steel
   • Excellent resistance to water
   • High Temperature Resistance
   • Can work with steel reinforcements
