Supplementary Factors in Structural Masonry
Mortar and Grout
Two integral components to any masonry project are mortar and grout. Mortar is a paste that sticks the masonry units together, while grout is the fluid form of concrete used to fill voids. Together, they form the bond that holds the structure together and transfers loads from one masonry unit to the next.
Masonry Connectors
Connectors are metal components used in the construction of a masonry structure. They improve the masonry structure’s performance in resisting lateral and seismic forces. Some common types of connectors used in masonry construction include horizontal joint reinforcement, anchors, and wall ties.
Designing and Testing
Planning is a vital stage in any structural masonry project. Design involves analyzing architectural plans and conducting necessary calculations to ensure the structure can resist loads, winds, and seismic activity. Furthermore, performance testing is done to validate that a structure meets certain international and local building code standards. Tests focus on compressive strength, moisture absorption, and frost resistance.
Masonry Variations
Masonry construction is not limited to the traditional units of bricks, blocks, and stone. There are variations that have been developed over time to meet specific construction requirements. Here are a few to consider:
- Aerated Concrete: This is a type of lightweight concrete that offers thermal insulation.
- Glass Blocks: These allow natural light to shine into a structure without sacrificing privacy or security.
- Ceramic Tiles: Primarily used in decorative elements, these are hardened clay units glazed to resist moisture.
Masonry Installation Practices
Proper installation of masonry units requires professionals with skill and experience. It must meet guidelines established by the Masonry Standards Joint Committee. Some of these guidelines include:
- Alignment: Units should be laid out in a straight line and at an angle that assures stability.
- Crack Control: Expansion and contraction of masonry materials can lead to cracking. Proper control measures should be put in place to mitigate damage.
- Mix Proportions: The ideal mix of mortar or grout contributes to the overall strength of the masonry structure.
Environmental Considerations
Structural masonry is a highly sustainable technique. The units used are often sourced locally, reducing the carbon footprint associated with transportation. Furthermore, masonry buildings tend to last for several decades, reducing the need for frequent replacement.
Also, clay bricks and concrete blocks are recyclable, reducing waste. Masonry structures also offer superior performance in energy conservation due to their excellent thermal mass properties.
