Building Materials
Building Materials
Materials used in building construction, categorized into natural (wood, stone), artificial (bricks, cement), and composite (concrete, plywood).
Stones
Stones
Naturally occurring rocks found in the earth's crust, used in construction and as aggregates in concrete.
Weathering
Weathering
Refers to the process of breaking down rocks into smaller particles due to exposure to weather elements like frost, rain, and wind.

Study Notes
Building Materials: Stones
- Stones are naturally occurring materials commonly used in construction, serving as aggregates for concrete and a key component in historic monuments
- Stone prices increase with more complex shaping and texturing
- Stones originate from rock, with varied chemical compositions and forms
- Stones are categorized based on geological, physical, and chemical properties
Geological Classification of Stones
- Igneous Rocks: Formed from cooled magma (molten rock). Include Plutonic, Hypabyssal, and Volcanic rocks
- Sedimentary Rocks: Formed from deposited weathered material from pre-existing rocks. Agents of transport include frost, rain, wind, and flowing water
- Metamorphic Rocks: Formed by altered igneous or sedimentary rocks under high heat and pressure, a process called metamorphism
Physical Classification of Stones
- Stratified Rocks: Exhibit layered structures (planes of stratification/cleavage), easily splitting along these planes. Examples: sandstone, limestone, slate
- Unstratified Rocks: Lack layering, have compact crystalline grains, and resist splitting. Examples: granite, trap, marble
- Foliated Rocks: Have a tendency to split along a definite direction, though not necessarily parallel like stratified rocks. Common in metamorphic rocks
Chemical Classification of Stones
- Silicious Rocks: Predominantly silica. Hard and durable (e.g., granite, trap, sandstone)
- Argillaceous Rocks: Primarily clay. Hard and durable, but brittle (e.g., slate, laterite)
- Calcareous Rocks: Primarily calcium carbonate. Limestone (sedimentary) and marble (metamorphic)
Requirements for Good Building Stones
- High Crushing Strength: Minimum 100 N/mm² for structural integrity
- Desirable Appearance: Uniform color and aesthetic qualities suitable for facade applications
- Durability: Resistant to chemical weathering, atmospheric influences, and long-term structural integrity, influencing factors include composition, texture, and location within the structure.
