Placement of Reinforcing
Concrete is weak in resistance to tensile forces. Reinforcing is used primarily to resist tension and thus prevent cracking or failure of the concrete member under tension.
Tension May Be Induced By:
- Shrinkage of concrete as it hardens
- Temperature changes
- Bending and shear forces
Concrete Cover for Reinforcing Steel
To provide protection of reinforcing steel against corrosion and fire, a minimum cover of concrete must be furnished. Engineer to specify. Recommended cover:
- Slabs/walls

Understanding Consumer Preferences and Market Behavior
Consumer Preferences: Part of consumer behavior. A consumer compares different groups of items available for purchase through market baskets. A list with specific quantities of goods. It has assumptions about people’s preferences for one market versus another. Completeness: For any two market baskets A and B, a consumer will prefer A to B, will prefer B to A, or be indifferent between both. Transitivity: A consumer prefers A to B, and B to C, then will prefer A to C. More is better than less: Goods
