AAC Block Adhesive
What is an AAC Block Adhesive?
AAC block adhesive is a polymer-based multifunctional jointing material developed to provide excellent bonding, and durability, and to speed up the construction process of AAC blocks, fly ash bricks, concrete blocks, and other building materials. It’s a pre-mixed, easy-to-apply high-quality mortar made of cement, graded sand, and mixtures that substitute traditional 12-18 mm jointing mortar with a more adaptable 3-5 mm thickness.
The best AAC block adhesive is a versatile thin jointing material used especially for thin bed applications. This mortar is designed specially to give stronger, and more durable bonding between the blocks with optimum adhesive strength. AAC block adhesive Specification technical parameters that comply with ASTM C 1660-09 features, benefits, and uniform and consistent quality. It provides high tensile adhesion for good bonding strength. There are no shrinkage cracks at joints, and no curing is required after the application.
AAC Block Adhesive Vs Cement and Sand mortar
AAC block adhesive is a very good replacement for conventional cement and sand mortar. It requires thin bed joints and less quantity of AAC block adhesive consumption. It is ready for subsequent application in 24 hours. It is very economical and saves substantial costs compared to conventional mortar.
It saves a lot of time by eliminating the lengthy and cumbersome process of site mixing areas of application. It is highly recommended for masonry wall preparation by joining all different types of Autoclave Aerated Concrete (AAC) blocks, fly ash bricks, flatbed concrete blocks, etc with compressive strength.
In most residential structures, nowadays AAC block adhesive is used as the wall units, due to its various advantages. They are lightweight blocks that are quite easy to handle and are very sustainable. AAC blocks have good thermal insulation because they use fly ash in the production. Hence they are counted in the list of eco-friendly materials.
Cement and sand mortar has been used for masonry construction for many decades. But the use of conventional mortar and recently invented AAC blocks has led to a decline in construction quality, the reason being their mismatched properties. The cement mortar is heavier to bond with AAC blocks and also does not have good thermal insulation properties.
Hence, the need for the formulation of special adhesives to match the properties of AAC blocks. This AAC block adhesive has many advantages over conventional cement mortar when used with AAC blocks. The cost-effectiveness between AAC block adhesive and cement mortar is always debatable among contractors and homeowners. Here are the advantages of AAC block adhesive and its cost comparison with conventional cement sand mortar, so that you can make the right choice.
- Once fully dry it gains high strength and can be used up to full room height for fixing AAC blocks easily.
- AAC block adhesive guarantees the fixing of all kinds of absorbent bricks and concrete blocks.
- High coverage compared to the conventional block jointing mortar.
- Exceeds the strength of class one adhesive.
- Can be used with a minimum thickness of 2 mm to 6 mm.
- Water curing is not required.
- It Saves time and labor substantially.
- It spreads easily and has creamy workability.
- It has very low VOC and is suitable for green building credit points.
- Does not require mixing of any extra cement.
Some pointers on how to utilize AAC block adhesive:
- Using a good trowel, apply a thin coating of mixed adhesive to the AAC blocks in a thickness of 3 to 5mm, on which the blockwork will be done.
- After the first block is in place, check the best AAC Block Adhesive price of the same thickness on both sides of the block, keeping the line and level in mind.
- Clean off any excess adhesive that comes out of the block right away, and repeat the technique for the complete blockwork.
Our best AAC block adhesive has the following features:
- A thin jointing layer with high adhesive strength.
- Because the glue is pre-mixed, mixing and joining are simplified.
- The cost of adhesive is too low compared to cement mortar because the thickness is so thin (3 to 5mm) as a result, it is cost-effective.
- Neither the AAC blocks nor the adhesive requires curing.
- The high tensile strength can be achieved in a shorter period.
- Because the adhesive’s thickness is so thin, it prevents shrinkage fractures in joints.
- Because the glue is made of polymers, it has a low VOC content and is ideal for green buildings.
Benefits of AAC block adhesive
Less Material and Thin Joints: Compared to cement sand mortar, which requires 8-12 mm thick mortar joints, 3-4 mm of adhesive is sufficient to attach AAC blocks.
Construction is completed quickly: AAC block adhesive is a ready-to-use substance that only requires the addition of water for application. In block jointing mortar, the raw components must be balanced appropriately and then carefully mixed to make the paste, which takes time.
Saves Water: The adhesives are formulated in such a way that they are self-curing. No water is required for the curing of the adhesive, and as a result, they help in saving water as well as money.
Cleanliness of the site: The site environment can be readily kept clean because the procedure of mixing, transportation, and application is extremely well defined and hassle-free. Due to its self-curing nature, the cleanliness of the site is maintained.
Minimum Process Time: As no curing is required, the masonry wall is ready within just 24 hours. While in the case of cement sand mortar, curing is needed for at least 7 days.
Dry Material is Available throughout the Year: AAC block adhesive is available in dry form all year round, which may not be possible in the case of mortar. Sometimes it happens that moist sand is available, which has to be dried, and then only it can be used. This leads to an increase in the cost of the mortar.
Less Wastage: Cement mortar accounts for at least 20-30% of wastage during its use. While there is negligible or no waste during AAC block adhesive consumption
Thermal Insulation: The AAC block adhesive composition is specially formulated to match the thermal insulation properties of the AAC blocks. Due to this feature, the whole masonry acts as a thermal barrier which is not the case with cement mortar.
Quality Control: As the AAC block adhesive manufacturers produce the adhesives in factories under controlled conditions, the quality control measures can be effectively followed and the ultimate product is of much superior quality. However, cement mortar is prepared on-site, and it is generally difficult to maintain the quality of mortar as it is being prepared on-site. When the mortar is prepared on-site, it becomes difficult to check the raw material for quality. The AAC block adhesive manufacturers properly test the raw materials and then only use them in the manufacturing of the adhesives. This also ensures the AAC block adhesive composition over the batches does not vary.
Cost Comparison of AAC Block Adhesive and Mortar
The use of AAC blocks reduces the construction cost by almost 30%. which can reduce your overall construction cost in a huge manner. AAC block adhesive consumption also decreases the life-cycle cost which is not at all possible in the case of conventional CLC (Cellular Lightweight Concrete) blocks and clay bricks. AAC block adhesive along with being a very cost-efficient material also helps in decreasing the load on reinforced concrete blocks by 10%-15%. The material consumption in the cement mortar layer is 2.5 to 3 times more in comparison to AAC block adhesives. That definitely means that adhesives save a lot more labor, more time, and of course cost.
Thus from the above discussion, the AAC block adhesive is less expensive and more cost-effective in the long run. AAC block adhesive has many advantages and is much cheaper than conventional mortar. Owing to its advantages, the cost of curing, transportation, and the cost of labor is also reduced significantly. Hence, homeowners should consider buying the adhesive when constructing the house with AAC blocks.
