Study Notes
Construction Materials and Techniques
- Fine aggregate produced by crushing hard stone is called crushed stone sand.
- ProEst is used for different management such as asset, inventory, procurement, contract, and task.
Building Design and Construction
- Conventional steel building can withstand seismic force.
- PEB uses international design codes such as AISC, AISI, and MBMA.
- A revolutionary new development in building design is also known as solar paint.
Solar Paint and its Applications
- Solar paint combines titanium, which results in hydrogen sulphide.
- Solar paint is an alternative to rigid silicon flat panels.
- Perovskites are a range of materials used in solar paint.
- Solar paint is a liquid or solid paint.
Building Dynamics and Seismic Design
- Displacement towards the right indicates that the unisolated building is changing its shape from rectangle to triangle.
- The primary cause of earthquake damage to buildings is deformation.
- Acceleration increases because the base isolation system lengthens a building's period of vibration.
- The lead plug in a base isolated building reduces the energy of motion by converting it into heat.
Foundation Construction
- Vibro replacement is a method of constructing earthquake-resisting structures that involves replacing poor soil material.
- Vibro replacement is used in various soil types, including clay, lateritic, and sandy soil.
- Micro piles are moulded on the spot to serve as deep foundation and shaft.
- Micro piles are composed of sand and cement mortar and are thoroughly reinforced throughout their length.
- Micro piles are also known as pin piles, needle piles, or root piles.
- Advantages of micro piles include fast installation, allowing the use of small equipment, and allowing low overheads.
Soil Nailing
- The types of soil nailing are grouted nail, driven nail, and self-drilling soil nail.
- Grouted nail involves filling drill holes with cement grout after excavation.
- Driven nail involves mechanically driving nails to the wall during excavation.
Drainage and Soil Improvement
- PVDs are used to increase surcharging process.
- Methods of heating soil in situ include ground surface heating, heating through boreholes, and thermal piles.
