    AAC Block Jointing Mortar

    AAC (Autoclaved Aerated Concrete) blocks are lightweight, precast building materials that provide excellent thermal insulation, sound absorption, and fire resistance. For effective construction using AAC joint mortar, a specialized jointing mortar is required. AAC block jointing mortar is designed to ensure strong adhesion, easy application, and durability, making it an essential component for AAC block construction.

    Composition and Properties

    AAC block jointing mortar is a pre-mixed, ready-to-use product made from a blend of cement, graded sand, polymers, and additives. The formulation is specifically designed to provide the following properties:

    1. High Bond Strength: Ensures strong adhesion between AAC blocks near me, reducing the risk of cracks and structural failures.
    2. Water Retention: Maintains adequate moisture levels in the mortar, preventing premature drying and ensuring optimal curing.
    3. Workability: Easy to mix and apply, providing a smooth and consistent application that enhances the speed and quality of construction.
    4. Durability: Resistant to shrinkage and thermal expansion, maintaining structural integrity over time.

    1. Strong Bonding: The polymers and additives in the jointing mortar create a strong bond between the AAC block jointing mortar, ensuring the stability of the structure.
    2. Reduced Cracking: High bond strength minimizes the likelihood of cracks forming due to settlement or thermal movement.
    • Improved Construction Efficiency
    1. Ease of Use: Ready-to-use formulation simplifies the mixing process, allowing for quicker and more efficient application.
    2. Thin Joints: The mortar can be applied in thin layers (typically 3-5 mm), reducing the overall material usage and cost.
    • Thermal and Acoustic Insulation
    1. Energy Efficiency: The thin joints and high thermal insulation properties of AAC blocks, combined with the jointing mortar, contribute to improved energy efficiency in buildings.
    2. Sound Absorption: The mortar helps maintain the acoustic insulation properties of the AAC block near me, creating quieter indoor environments.
    • Durability and Weather Resistance
    1. Shrinkage Control: The specialized formulation reduces shrinkage and thermal expansion, preventing the development of cracks and ensuring long-term durability.
    2. Water Resistance: The mortar is designed to be resistant to water ingress, protecting the structure from moisture-related damage.

    Application Procedure

    Surface Preparation

    1) Clean Blocks: Ensure that the AAC block jointing mortar is clean, free from dust, and dry before application.

    2) Dampen Blocks: Lightly dampen the surface of the blocks to improve adhesion.

    • Mixing
    1. Consistent Mixing: Follow the manufacturer’s instructions to mix the mortar with water to achieve a smooth, lump-free consistency.
    2. Mixing Ratio: Typically, a ratio of 3:1 (mortar to water) is recommended, but this may vary based on the specific product.
    • Application


    1. Apply Thin Layer: Use a notched trowel to apply a thin layer (3-5 mm) of mortar on the AAC block jointing mortar.
    2. Position Blocks: Place the AAC joint mortar onto the mortar bed and press firmly to ensure proper adhesion.
    3. Align and Level: Use a spirit level to ensure the blocks are aligned and level. Adjust as necessary while the mortar is still workable.
    4. Remove Excess Mortar: Clean off any excess mortar that squeezes out from the joints before it sets.
    • Curing
    1. Adequate Curing: Allow the mortar to cure as per the manufacturer’s instructions, typically 24-48 hours, to achieve maximum strength and durability.

    AAC Concrete (Autoclaved Aerated Concrete)

    Autoclaved Aerated Concrete (AAC) is a lightweight, precast building material made from natural raw materials like sand, cement, lime, gypsum, and water, with a small amount of aluminum powder acting as a foaming agent. AAC blocks and panels are known for their excellent thermal insulation, sound absorption, and fire resistance properties, making them popular in modern construction.

    Manufacturing Process

    1. Mixing and Foaming: The raw materials are mixed, and the aluminum powder reacts with the lime and water, producing hydrogen gas that creates small, evenly distributed air pockets.
    2. Pre-Curing: The mixture is poured into molds and allowed to set and rise partially.
    3. Cutting: The partially set material is cut into blocks or panels of the desired size.
    4. Autoclaving: The cut blocks are cured in an autoclave under high pressure and temperature, which gives AAC concrete its strength and unique properties.


    1. Lightweight: AAC blocks are much lighter than traditional concrete, reducing the overall weight of the structure.
    2. Thermal Insulation: The air pockets in AAC provide excellent thermal insulation, reducing the need for additional insulation materials.
    3. Sound Absorption: The porous structure of AAC blocks near me absorbs sound, making it ideal for noise reduction.
    4. Fire Resistance: AAC concrete is non-combustible and can withstand high temperatures, providing excellent fire resistance.
    5. Eco-Friendly: Made from non-toxic materials, AAC is recyclable and has a lower environmental impact compared to traditional concrete.


    1. Residential Buildings: Walls, floors, and roofs for homes.
    2. Commercial Buildings: Office buildings, shopping centers, and industrial structures.
    3. Infrastructure Projects: Bridges, tunnels, and other large-scale constructions.

    AAC Joint Mortar

    AAC joint mortar is a specially formulated adhesive used to bond AAC blocks near me and panels. It is designed to provide a strong, durable bond while being easy to apply and ensuring minimal thermal bridging.


    AAC joint mortar is typically composed of cement, fine sand, polymers, and various additives to enhance its properties, such as workability, water retention, and adhesion strength.


    1. High Bond Strength: Ensures a strong, secure bond between AAC block jointing mortar, preventing movement and cracks.
    2. Water Retention: Maintains moisture during the curing process, allowing for optimal setting and bonding.
    3. Easy Application: The mortar is pre-mixed and requires only the addition of water, simplifying the mixing process.
    4. Thin Joints: Can be applied in thin layers (usually 3-5 mm), reducing material usage and enhancing the thermal efficiency of the wall.
    5. Durability: Resistant to shrinkage, cracking, and thermal expansion, ensuring long-lasting performance.
