Properties and Applications of Modern Construction Materials
Stone for Construction
Igneous Rocks: Composed of silicates and other compounds such as aluminum, iron, calcium, magnesium, sodium, and potassium, these are formed by magma inside the earth. Varieties include:
- Crystal: Very hard and resistant to weathering (granite, gabbro, and diorite).
- Glass structure: Basalt, pumice, and liparite (rhyolite).
Sedimentary Rocks
Formed from sediments over many years. According to their composition:
- Siliceous rocks: Formed by sand and gravel.
- Limestones: Include calcite and gypsum.
- Clay: Comes from sedimentary deposits.
Metamorphic Rocks
Produced by changes in the crystal structure. Examples include schist and marble.
