List four key factors to consider when selecting building materials.
Purpose, climate, cost and availability, and durability.
Color, brand, size, and popularity.
Shape, texture, weight, and trendiness.
Location, style, age, and maintenance.
Mention three mechanical properties of building materials.
Strength, elasticity, hardness.
Color, texture, glossiness.
Transparency, opacity, reflectivity.
Conductivity, magnetism, radioactivity.
Explain the difference between natural and manufactured materials with one example each.
Natural materials occur in nature (e.g., wood); manufactured materials are processed (e.g., concrete).
Natural materials are always man-made (e.g., plastic); manufactured materials are found in nature (e.g., stone).
Natural materials are only used in construction; manufactured materials are only used in clothing.
Natural materials are processed in factories; manufactured materials grow on trees.
Give two advantages of using glass in buildings.
Provides natural lighting and aesthetic appeal.
Reduces the strength of the building and increases maintenance costs.
Blocks all outside views and makes rooms darker.
Increases the weight of the building and reduces energy efficiency.
State two common testing methods used to assess building material quality.
Laboratory testing (compressive strength test), field testing (slump test).
Visual inspection, painting.
Sound test, color matching.
Weighing, painting.
