Mortar is a binder used in construction to bond stones, bricks, and concrete blocks. Its primary purpose is to create structurally sound buildings and fill and seal the spaces between different materials in a project.
Properties of Mortar & What Mortar is Made of
Mortar is made of a mix that includes water, a binder like cement, lime, or a mixture of both, and an aggregate such as sand. These components add to the properties of mortar in building construction:
1. Workable: The mix is easy to spread and allows for the efficient laying of bricks or stones.
2. Adhesive: It provides strong bonding between masonry units.
3. Durable: Once set, it becomes resistant to environmental and mechanical stresses.
4. Plasticity: Mortar can be moulded to fill the shape of the masonry units it joins.
5. Resistance to Weathering: High-quality mortar resists the effects of weather and prevents water penetration.
Types of Mortar in Construction
Different types of mortar cater to specific construction needs:
1. Lime Mortar
2. Cement Mortar
3. Mixed Mortar
4. Special Mortars
Choosing the Right Mortar in Construction for Home Building
Mortar is used as a binding agent to make projects stand the test of time. Builders should weigh these factors to make the best choice:
1. Assess Structural Requirements: Heavy-duty work, such as load-bearing walls, might require cement mortar.
2. Consider Climate Conditions: In areas with heavy rainfall, a mortar with good resistance to water and dampness may be beneficial.
3. Think About Aesthetics: Use lime mortar for a traditional appearance and special mortars for modern finishes and colours.
4. Compatibility: Lime mortar might be the best choice for restoring or renovating older structures due to its compatibility with traditional materials and techniques.
Beyond understanding the meaning of mortar, it’s important to understand the differences between mortar and concrete for your homebuilding project.
