Product Description
Aerated block-specific masonry mortar, also known as aerated concrete masonry mortar or thin-layer mortar, is a specialized mortar designed specifically to complement aerated concrete blocks (AAC Blocks)—a new type of wall material characterized by its porosity and high water absorption.
Its key difference from traditional cement mortar lies in its high water-retention capacity and strong bonding performance. In traditional mortar, moisture tends to be quickly absorbed by aerated blocks, leading to insufficient cement hydration, reduced strength, and poor adhesion—issues that can trigger cracks and hollow sounds in walls. Specialized mortar addresses these problems perfectly by incorporating admixtures such as water-retaining agents and redispersible latex powders.
3. Core Features
1. High water-retention capacity: Effectively prevents aerated concrete blocks from rapidly absorbing moisture, ensuring complete hydration of the cement in the mortar and thereby achieving high strength.
2. High Bonding Strength: Forms an extremely strong bond with the surface of aerated concrete blocks, preventing hollowing and detachment of the wall.
3. Good workability and ease of construction: The mortar is soft and smooth, with fully filled joints, making construction effortless and highly efficient.
4. Excellent crack resistance: Reduces wall cracks caused by mortar shrinkage or poor adhesion.
5. Thin-layer masonry is achievable: Typically, a thin-mortar dry-laying method (with mortar joint thickness ranging from 3 mm to 5 mm) is employed, which can effectively reduce thermal bridges in walls and enhance the overall thermal insulation performance of the wall.
4. Technical Parameters
Technical indicators Unit Performance Requirements/Typical Values Testing standards Water retention rate % ≥ 99% JGJ/T 70-2009 Tensile bond strength MPa ≥ 0.30 (28 days, with aerated concrete blocks) JGJ/T 70-2009 ≥ 0.20 (14 days, with aerated concrete blocks) Compressive strength MPa Available in design-specific grades such as M5, M7.5, M10, etc. GB/T 17671-2021 Consistency mm According to construction requirements, it is typically between 70 and 90. JGJ/T 70-2009 Setting time h Usually 3–9 hours (depending on the product formulation). JGJ/T 70-2009 Dry density kg/m³ ≤ 1800 GB/T 25181-2019 Shrinkage rate % ≤ 0.50% JGJ/T 70-2009 5. Scope of Use
1. Core application ： Masonry and plastering of autoclaved aerated concrete blocks (AAC blocks).
2. Applicable Building Types :
● Interior and exterior infill walls for various types of civil and industrial buildings.
● Buildings with high requirements for thermal insulation, heat retention, and fire resistance.
● Enclosing walls for frame structures and steel structures.
3. Construction Process ： It is suitable for both traditional thick-mortar masonry (mortar joint thickness ≤15mm) and is particularly recommended for thin-layer masonry (mortar joint thickness 3mm–5mm), enabling full utilization of its performance and the advantages of aerated concrete blocks.
Precautions:
● Strictly prohibited: Do not use on low-water-absorption substrates such as sintered bricks and solid concrete bricks, as their excessively high water-retention rate can prevent moisture from evaporating, leading to prolonged dampness and compromising strength.
● Substrate Preparation: Before construction, the substrate must be clean and free of dust and oil stains. For substrates that are very dry, you may lightly dampen them, but there must be no visible standing water on the surface.
