Special masonry mortar for aerated blocks, also known as aerated concrete masonry mortar or thin-layer mortar, is a specially designed mortar for aerated concrete blocks (AAC Block), a new type of porous and highly water-absorbent wall material.
Its key difference from traditional cement mortar lies in its high water retention and high adhesion. Traditional mortar moisture is quickly absorbed by aerated blocks, causing insufficient cement hydration, reduced strength, and poor bonding, leading to wall cracking and hollowing issues. The special mortar perfectly solves these problems by adding water-retaining agents, redispersible latex powder, and other additives.
Core Features:
1. High Water Retention: Effectively inhibits the rapid absorption of water by aerated blocks, ensuring full hydration of cement in the mortar to form high strength.
2. High Bonding Strength: Forms a very strong bond with the surface of aerated blocks, preventing hollowing and detachment of the wall.
3. Good Workability and Construction Performance: The mortar is soft and smooth, with full joints, labor-saving and efficient construction.
4. Excellent Crack Resistance: Reduces wall cracks caused by mortar shrinkage or poor bonding.
5. Enables Thin-Layer Masonry: Usually uses thin slurry dry masonry method (joint thickness 3mm-5mm), effectively reducing thermal bridges in walls and improving overall thermal insulation performance.
Technical Parameters
Technical Indicators Unit Performance Requirements / Typical Values Test Standards Water Retention Rate % ≥ 99% JGJ/T 70-2009 Tensile Bond Strength MPa ≥ 0.30 (28 days, with aerated block) JGJ/T 70-2009 ≥ 0.20 (14 days, with aerated block) Compressive Strength MPa Can be designed as needed, such as M5, M7.5, M10, etc. GB/T 17671-2021 Consistency mm Usually between 70-90 according to construction requirements JGJ/T 70-2009 Setting Time h Usually 3-9 hours (depending on product formula) JGJ/T 70-2009 Dry Density kg/m³ ≤ 1800 GB/T 25181-2019 Shrinkage Rate % ≤ 0.50% JGJ/T 70-2009 Scope of Use
1. Core Applications: Masonry and plastering of autoclaved aerated concrete blocks (AAC Block).
2. Applicable Building Types:
● Interior and exterior infill walls of various civil and industrial buildings.
● Buildings with high requirements for thermal insulation and fire resistance.
● Enclosure walls of frame structures and steel structures.
3. Construction Techniques: Suitable for traditional thick-layer masonry (joint ≤15mm), but thin-layer masonry method (joint 3mm-5mm) is recommended to fully utilize its performance and the advantages of aerated blocks.
Precautions:
● Strictly Prohibited: Not to be used for masonry of sintered bricks, solid concrete bricks, and other low water absorption substrates, as its high water retention will prevent moisture evaporation, causing long-term dampness and affecting strength.
● Substrate Treatment: Before construction, the substrate should be clean, free of dust and oil. For very dry substrates, slight moistening is allowed, but no standing water on the surface.
