Study Notes
Engineering Geology
- Engineering geology combines geology with civil engineering projects, like bridge design, dam construction, and landslide prevention.
- The course syllabus covers:
- General geology
- Petrology
- Mineralogy
- Structural Geology and Rock Mechanics
- Geological and geophysical investigation in civil engineering
- Energy sources
- The course has three exams: prelim, midterm, and final.
Earth
- Third planet from the sun.
- Only known astronomical object to harbor life.
- Sustains liquid surface water, making it an "ocean world."
- 70.8% of Earth's crust is covered in ocean.
- Remaining 29.2% is land.
Petrology
- Branch of geology focused on the composition, structure, and origin of rocks.
- Petrography is a subdiscipline of petrology that focuses on describing and classifying rocks.
- Petrologic research often involves examining rocks in outcrops, hand samples, and under microscopes.
Measuring Tiny Linear Measurements
- Micron: One-millionth of a meter or 10-6 meters.
- Micrometer (micrometer caliper): An instrument used for making precise linear measurements of dimensions like diameter, thickness, and length.
- Vernier Caliper: A linear measuring instrument with a scaled rule and sliding vernier to measure dimensions.
Importance of Petrology in Civil Engineering
- Provides information about physical rock properties like texture, structure, mineral composition, and chemical composition.
- This helps evaluate rock strength, durability, color, appearance, and workability.
Concrete
- A hard, strong building material made by mixing cement, mineral aggregate (sand and gravel), and water.
- Cement: Derived from high-quality limestone or calcium carbonate deposits.
- Silica: Silicon dioxide, commonly found in nature as quartz.
Gravel
- Collection of loose material made mainly of rock fragments.
- Common types: basalt, limestone, and sandstone.
Sand
- Formed by the breakdown of rocks through weathering and erosion over millions of years.
