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.
