    Study Notes

    Foundation Types

    • Deep foundations are used for poor soil conditions.
    • Spread footings, slab on grade, and strip foundations are typically used for stable soil conditions.

    Concrete Mixtures

    • Concrete for mass concrete works has a proportion of 1:2.5:5 (cement: sand: gravel).
    • Components of a concrete mixture are: cement, sand, gravel, and water.

    Structural Elements

    • Retaining walls resist lateral forces from the soil.

    Concrete Properties

    • Fresh concrete consistency is measured using a slump test.

    Splice Connections

    • Splice connections join structural elements for load continuity.

    Building Components

    • Substructure supports the superstructure of a building.
    • Superstructure is the visible part of a building that includes walls, floors, and roof.

    Concrete Proportioning

    • Concrete proportioning for suspended slabs, beams, columns, arches, stairs, and walls of 100mm (4") thickness is typically 1:2:4 (cement: sand: gravel).

    Water-Cement Ratio

    • The average water-cement ratio is approximately 5.5 gallons of water per bag of cement.

    Formworks

    • Formworks shape and support fresh concrete.
    • Snap ties, spreaders, yokes, and she bolts are used to keep forms stable under the pressure of wet concrete.

    Construction Drawings

    • Construction working drawings provide necessary information for building construction.

    Pre-construction Process

    • The pre-construction process includes planning, procurement, and design, but not excavation.

    Aggregate Types

    • Coarse aggregates are larger than 6 mm in size.

    Concrete Joist Construction

    • Concrete joist construction is used for short-span residential floors.

    Steel Floor Systems

    • Lateral bracing in steel floor systems stabilizes beams and columns.

    Concrete Floor Joints

    • Control joints in concrete floors prevent random cracking.

    Tile Types

    • Porcelain tiles, being denser and less porous than ceramic tiles, are more durable for both indoor and outdoor use.
