BUILDING CONSTRUCTION MATERIALS AND TECHNIQUES

1. INTRODUCTION TO BUILDING MATERIALS AND TECHNIQUES

1.2 Meaning of Building Construction

Building construction refers to the process of assembling materials to create a structure that is safe, functional, and durable. It involves planning, design, material selection, and execution of works according to specifications.

Construction combines:

  • Materials

  • Skilled labor

  • Tools and equipment

  • Construction techniques

1.3 Classification of Building Materials

1. Natural Materials

Obtained directly from nature with little processing.
Examples:

  • Stone

  • Timber

  • Sand

  • Clay

2. Manufactured (Artificial) Materials

Produced through industrial processes.
Examples:

  • Cement

  • Concrete

  • Steel

  • Glass

  • Bricks

1.4 Importance of Building Materials

Building materials are important because they:

  • Provide strength and stability

  • Ensure durability

  • Improve appearance (aesthetics)

  • Provide insulation (thermal and sound)

  • Ensure safety and comfort

Proper selection of materials affects the overall performance and lifespan of a building.

1.5 Factors Affecting Selection of Materials

When selecting materials, consider:

  1. Cost and availability

  2. Strength and durability

  3. Climate conditions

  4. Maintenance requirements

  5. Environmental impact

  6. Local building regulations
