BUILDING CONSTRUCTION MATERIALS AND TECHNIQUES
1. Introduction
Building construction materials and techniques refer to the materials used in construction and the methods applied to assemble them to form safe, durable, and functional structures. The selection of materials and techniques depends on factors such as cost, availability, climate, strength requirements, and intended use of the building.
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:
-
Cost and availability
-
Strength and durability
-
Climate conditions
-
Maintenance requirements
-
Environmental impact
-
Local building regulations
