Lecture Notes: Plain Cement Concrete (PCC)

Introduction to Concrete

• Concrete is a composite material.
  • Components:
    • Binder: Cement or lime
    • Fine Aggregates: Sand
    • Coarse Aggregates: Larger stones or gravel
    • Water
• Process:
  • Fine aggregates fill the voids between coarse aggregates.
  • Binder fills the voids between fine aggregates.
  • Binder reacts with water to bind aggregates, forming a robust matrix.

Plain Cement Concrete (PCC)

• Definition: Simplest form of concrete.
  • Composed of basic ingredients: binder, fine and coarse aggregates, water.
• Uses:
  • Construction of pavements.
  • Building areas requiring low tensile strength.
  • Bed concrete below footings.
  • Sill concrete below windows and ventilators.
