What is it used for
Residential Construction: Mortar is used for laying bricks and blocks in home construction, including walls, chimneys, and fireplaces.
Commercial Construction: Employed in constructing office buildings, shopping centers, and other commercial structures, ensuring strong and stable brickwork.
Restoration Projects: Used in the restoration and repair of historic buildings, matching the original mortar for authenticity and durability.
Dimensions
Volume: Typically purchased by the cubic meter (m³) or in pre-mixed bags
Weight: Approximately 1.7 tons per cubic meter (1700 kg/m³)
What it’s Made From
Cement: Acts as the primary binding material, providing the necessary strength for the mortar.
Lime: Often added to enhance workability and water retention.
Sand: Provides the bulk of the mortar mix, ensuring stability and uniformity.
Water: Essential for mixing and hydrating the cement and lime.
Additives: Can include plasticizers, accelerators, and retarders to improve workability and setting time.
Variations
Type N Mortar
Description: General-purpose mortar with balanced strength and flexibility.
Applications: Suitable for exterior and above-grade walls.
Type S Mortar
Description: Higher strength mortar with enhanced load-bearing capacity.
Applications: Ideal for foundations, retaining walls, and other structural applications.
Type M Mortar
Description: High compressive strength mortar, extremely durable.
Applications: Used in severe conditions such as below-grade applications, stone masonry, and high-traffic areas.
Installation
Tools Required:
Trowel | Mixing bucket | Spirit level | Pointing tool | Mason's hammer
Materials Required:
Mortar mix | Water | Brick or block units
Step-by-Step Guide:
Preparation: Ensure all surfaces are clean and free from dust or debris.
Mix Mortar: Combine mortar mix with water as per the manufacturer's instructions until achieving a workable consistency.
Apply Mortar: Spread a layer of mortar onto the base and apply to the edges of the bricks or blocks.
Lay Units: Position the bricks or blocks, pressing them into the mortar bed and tapping into place.
Check Level: Use a spirit level to ensure each layer is even and aligned correctly.
Point Joints: Once the mortar starts to set, smooth the joints with a pointing tool for a clean finish.
Curing: Allow the mortar to cure adequately, protecting it from harsh weather conditions during the initial setting period.
Technical Specification
Compressive Strength: Varies based on mix design, typically between 5 MPa to 20 MPa.
Workability: Should be easy to spread and shape, adhering well to surfaces.
Durability: Resistant to weathering, freeze-thaw cycles, and chemical exposure.
Certification
British Standard (BS EN 998-2): Specifies requirements for mortar for masonry.
ISO 14001: Environmental management certification, ensuring responsible production processes.
