Masonry01:28

Masonry

Masonry, known for its strength, durability, and aesthetic versatility, encompasses construction with solid stone or man-made units like bricks, clay tiles, terra cotta, and concrete blocks, combined to form structures like walls, floors, and arches. These units are placed in a systematic fashion, known as coursing, and are bound together using mortar—a mixture typically made of water, cement, and sand.
The process of building with masonry is hands-on and can be executed with basic tools. A...
Spanning Openings in Brick Walls01:20

Spanning Openings in Brick Walls

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...
Reinforced Brick Masonry01:15

Reinforced Brick Masonry

Reinforced brick masonry is an advanced construction technique that enhances the structural integrity of brick walls by incorporating steel reinforcements. These reinforcements are either placed within the hollow cores of bricks or sandwiched between two layers of masonry, known as wythes, and are then secured in place with grout. Grout is a fluid mixture composed of Portland cement, aggregate, and water, providing the necessary bonding agent for the steel and brick.
To fortify brick walls...
Masonry Cavity Walls01:26

Masonry Cavity Walls

Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.
Maintaining a clean cavity during construction is...
Masonry Loadbearing Walls01:16

Masonry Loadbearing Walls

Masonry load-bearing walls, constructed from materials like brick, stone, or concrete masonry units, serve as a crucial component in building structures by supporting the loads from floors and roofs and transferring them to the foundation. These walls, known for their compressive strength, can be reinforced or unreinforced to suit different building needs, accommodating both the dead and live loads while maintaining safety through lower working stresses compared to the materials' ultimate...
Posttensioned Masonry Walls01:15

Posttensioned Masonry Walls


Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
