Credits: 2 (1 Lecture, 1 Tutorial)
Concept of Building Materials in Architecture
Building materials are shaped by cultural traditions.
Architecture is described as conservative and traditional, affecting how materials are utilized.
Historical Perspective
Ancient Greeks used timber-like presentations in stone temple designs.
Adoption of Reinforced Cement Concrete (RCC) saw the continuity of traditional forms (columns, capitals)
RCC has the unique attribute of being molded into varied shapes, surpassing traditional limitations.

Page 12: Reinforced Cement Concrete (RCC)
Definition of RCC
RCC is a composite material where concrete's compressive strength is bolstered by steel's tensile strength.
Page 13: Understanding Components of RCC
Structure of RCC
Solid Material: Concrete (bond)
Fluid Material: (in its cured state)
Page 14: Key Ingredients of Concrete
Composition of Concrete
Cement: Serves as the primary binding agent.
Aggregates: Often categorized into fine and coarse materials (sand and stone).
Water: Essential for the hydration process.
Additives: Materials to enhance properties (e.g., strength and fluidity).
Page 15: Reinforcement Materials
Types of Reinforcements
Smooth Steel Bars: Basic reinforcement applications.
Striated Reinforcement: For improved bonding and tension handling.
Other Options: Glass fiber and FRP materials for specialized applications.
Page 16: Comparison of Concrete and Steel
Strength Analysis
Tensile Strength: Concrete = Poor, Steel = Good
Compressive Strength: Both exhibit good characteristics but may buckle under extreme conditions.
Page 17: Additional Strength Comparisons
Property | Concrete | Steel |
|---|---|---|
Tensile Strength | Poor | Good |
Compressive Strength | Good | Good, buckles under compression |
Durability | Good | Poor due to corrosion without protection |
Fire Resistance | Good | Poor due to rapid loss of strength |
