Study Notes
Stone and Brick Masonry Construction
- Stone masonry involves constructing buildings using stones, cut and shaped or natural form. It creates walls, arches, columns, etc.
- Ashlar Masonry: Stones are finely dressed, laid in horizontal courses with thin mortar joints.
- Rubble Masonry: Stones are rough and irregular, often laid without dressing, with wider mortar joints.
- Quoins: Corner stones, typically larger and more decorative than other stones.
- Coursed Masonry: Stones laid in horizontal courses of uniform thickness.
- Random Rubble Masonry: Stones of irregular sizes without uniformity in courses.
Technical Terms in Stone Masonry
- Quoin bricks/perpends: 10 cm bricks at the corners.
- Quoin headers/closers: Specific corner stones.
- Bed joint: Joint where stone rests.
- Courses: Horizontal layers of stone.
- Mortar: Material used to bind stones.
- Headers/stretchers: Stones laid in different directions.
General Principles for Construction
- Selection of Stone: Durable, strong, resistant to weathering, uniform texture, and free from harmful elements.
- Stone Preparation: Stones should be properly dressed and cut to required dimensions for even surfaces for better bonding.
- Mortar: Made from sand, lime, and cement—needs strength and flexibility for adjustments.
- Bonding and Jointing: Adequate bonding between stones ensures wall stability. Thin mortar joints (6-10 mm) are ideal to reduce water penetration.
- Course Leveling: Maintain uniform courses' height and horizontal & vertical alignment.
- Curing: Maintaining stonework moist for a time after placing to ensure proper mortar setting, increasing strength.
- Thickness of Walls: Determined by stone size, weight, and building's structural needs (Load-bearing walls are thicker than partition walls).
Selection of Stone for Masonry
- Strength: Stone should bear the structure's load.
- Durability: Resistance to weathering and wear, especially in extreme weather regions.
- Workability: Ease of cutting and shaping.
- Cost: Availability and transportation impact selection.
Brick Masonry Construction
- Uses bricks (clay, concrete, or stone) to build walls, floors, other structures. Bound together with mortar.
- Course: A horizontal layer of bricks
- Bed: The flat surface of the brick resting on mortar.
- Perpendicular Joint: The joint perpendicular to the bed and facing outward.
- Header: Brick laid with its shorter side exposed.
- Stretcher: Brick laid with its longer side exposed.
- Bond: The arrangement of bricks for strength & stability.
General Principles for Brick Construction
- Selection of Bricks: Uniform size, well-burned, free from cracks, appropriate compressive strength.
- Mortar: Correct mix for sufficient bonding strength and flexibility.
- Laying of Bricks: Staggered joints for strong bonds and filled mortar to avoid voids.
Commonly Used Types of Brick Bonds
- Stretcher Bond: Simple, bricks laid with long sides exposed, non-load-bearing.
- Header Bond: Strong, bricks laid with short sides exposed (headers), interlocking and used in load-bearing walls.
- English Bond: Alternating stretchers and headers.
- Flemish Bond: Alternating stretchers and headers with a more decorative pattern, both load-bearing and non-load-bearing.
Aesthetic Qualities
- The stone or brick should have an attractive appearance suitable for building design.
- Considerations for aesthetics are key.
Alignment, Curing, and Wall Thickness
- Alignment: Brick placement for plumb & level, aesthetically pleasing walls.
- Curing: The process of ensuring mortar sets firmly.
- Wall Thickness: Influenced by the load-bearing or non-load-bearing aspect.
