Materials Science in Civil Engineering
CE 336 Introduction to Construction Materials
2
Role of Material Science in CE

• Combining several sciences
• Chemistry
• Physics
• Mechanics
• Behavioral understanding of materials is based on
  knowledge of these sciences.

3
Predicting Behavior

• Civil Engineers design complex systems using
  relationships between
• Stress vs. Strength
• Strain vs. Deflection
• Exposure vs. Durability
• Risk vs. Consequence
• Cost vs. Aesthetics Life Cycle
• Others
