Dryze Mix BJM (Block Jointing Mortar):
Dryze Mix BJM is a high-quality, polymer-modified block joining mortar specifically designed for the construction of walls using AAC blocks, concrete blocks, fly ash bricks, and other types of masonry units. It provides a thin yet highly durable and strong adhesive bond between blocks, which eliminates the need for traditional sand-cement mortar. This ready-to-use formulation ensures faster, easier, and more efficient block joining, resulting in better masonry construction and reduced construction time.
- Key Features of Dryze Mix BJM:
- Typical Applications of Dryze Mix BJM:
- Key Benefits of Dryze Mix BJM:
- Mixing and Application:
- Pre-Mixed, Ready-to-Use:
- Dryze Mix BJM comes as a pre-mixed dry powder that only requires the addition of water. This eliminates the need for on-site preparation of cement-sand mortar and ensures consistent quality with each batch.
- Thin Joint Application:
- Unlike traditional thick mortar (10-12 mm), BJM allows for a thin joint application of only 2-3 mm, which reduces material consumption while still providing a strong, durable bond.
- The thin jointing mortar ensures that the walls remain even and smooth, improving the overall appearance and reducing plaster consumption.
- High Bonding Strength:
- The polymer-modified formulation of BJM provides excellent adhesion and bonding strength between blocks, ensuring the stability and durability of the wall structure.
- It prevents the formation of cracks and gaps, ensuring that the blocks remain securely bonded over time.
- Fast Curing and Setting Time:
- BJM offers quick setting properties, which allows for faster construction. This helps in speeding up the project timeline without compromising on quality or strength.
- Its fast curing time means that work can proceed more efficiently, allowing for quicker wall assembly compared to traditional methods.
- Water Retention and Resistance:
- The product has excellent water-retaining properties, which prevent the mortar from drying out too quickly, leading to better curing and enhanced bonding strength.
- It also offers water-resistant properties, preventing water seepage through the joints, which is crucial for long-term durability in humid or wet conditions.
- Improved Workability:
- Dryze Mix BJM is designed for easy application. It has a smooth consistency, making it easier for masons to spread and apply between blocks. This reduces labor effort and increases work efficiency.
- Reduced Shrinkage:
- The adhesive has low shrinkage properties, which helps in preventing cracks that typically occur due to shrinkage in conventional cement-sand mortar.
- This reduces the chances of cracks forming between block joints, enhancing the overall strength and longevity of the structure.
- Cost-Effective:
- By using a thin joint layer, BJM reduces material consumption significantly compared to traditional mortar. The reduction in material, faster application, and lower wastage lead to overall cost savings in the construction process.
- Less plaster is required since the wall is more uniform, reducing the finishing costs.
- AAC Block Joining:
- Ideal for Autoclaved Aerated Concrete (AAC) block masonry, providing strong adhesion and ensuring long-term stability of AAC block walls.
- Concrete and Fly Ash Block Masonry:
- Dryze Mix BJM is perfect for use with other types of masonry units such as concrete blocks, fly ash bricks, hollow blocks, and lightweight blocks, ensuring a strong and durable bond between the units.
- Residential, Commercial, and Industrial Construction:
- It is widely used in the construction of residential buildings, commercial complexes, and industrial structures, offering superior performance for a variety of masonry applications.
- Renovation and Repair Works:
- BJM is also suitable for repair or renovation projects where AAC or other types of blocks are used. Its quick setting and ease of use make it ideal for patchwork and minor structural changes.
- High Bond Strength: The polymer-modified formulation provides superior bonding between blocks, enhancing the overall strength and stability of the masonry structure.
- Efficient Construction: Its quick setting time and easy application allow for faster construction, reducing project timelines and labor costs.
- Water Resistance: The water-resistant properties prevent moisture ingress, which is especially beneficial in wet or humid environments.
- Crack-Free Finish: Low shrinkage properties help in reducing the occurrence of cracks, ensuring long-lasting, aesthetically pleasing masonry walls.
- Cost-Effective: By reducing material consumption and wastage, BJM provides an economical solution for masonry construction.
- Mixing:
- Dryze Mix BJM is supplied in a dry powder form and needs to be mixed with clean water to form a workable adhesive paste.
- The water-to-powder ratio should be followed as recommended by the manufacturer to achieve the desired consistency.
- Application:
- The adhesive is applied using a trowel or spatula to create a thin layer (approximately 2-3 mm thick) on the surface of the block.
- The blocks should be laid and pressed together immediately after the application of the adhesive to ensure a strong bond.
- There’s no need to soak the blocks in water before application, which saves time during construction.
- Curing:
- Although the adhesive has good water retention, light curing with water for a few days may be recommended to enhance bond strength and performance.
- Coverage:
- One of the advantages of Dryze Mix BJM is its high coverage. A 40 kg bag typically covers a larger area than traditional mortar due to the thin joint application, making it more cost-effective.
Limitations:
- Surface Preparation: The blocks should be clean, dry, and free from dust or loose particles to ensure proper adhesion.
- Not Suitable for Structural Bonding: While BJM is ideal for block masonry, it is not suitable for load-bearing structural joints, which may require specialized adhesives.
Dryze Mix BJM is a highly efficient, ready-to-use block joining mortar designed to provide superior bonding for AAC blocks, concrete blocks, and other masonry units. Its pre-mixed formula, high bond strength, and thin joint application make it an ideal choice for faster, more efficient wall construction with reduced material consumption. Its water-resistant, crack-free, and durable properties ensure long-lasting performance, making it a reliable solution for residential, commercial, and industrial projects.
