AAC Block Masonry Mortar

Product Overview

AAC Block Masonry Mortar, also known as aerated concrete masonry mortar or thin-layer mortar, is a specialized mortar designed for autoclaved aerated concrete blocks (AAC Blocks)β€”a porous, highly absorbent new wall material.

The key difference from traditional cement mortar lies in its high water retention and high bonding strength. Traditional mortar moisture is easily absorbed by AAC blocks, leading to insufficient cement hydration, reduced strength, weak bonding, and causing wall cracking, hollowing and other issues. Specialized mortar perfectly solves these problems through the addition of water retention agents, redispersible polymer powder and other admixtures.

Product Features

High Water Retention
Water retention β‰₯90%, effectively prevents AAC blocks from rapidly absorbing moisture, ensuring sufficient cement hydration and stable strength development.
Strong Bonding Performance
14-day bond strength β‰₯0.2MPa, provides excellent adhesion with aerated concrete blocks, reducing risks of hollowing and wall detachment.
High Compressive Strength
Compressive strength β‰₯5.0MPa, meeting load-bearing requirements of AAC block wall structures.
Thin-Layer Construction
Supports 3-5mm thin-layer masonry, reducing thermal bridges, improving wall insulation performance and saving materials.
Excellent Workability
Use within 2 hours after mixing, providing ample working time with convenient operation and high efficiency.
Strong Adaptability
Specifically developed for aerated concrete blocks, perfectly solving traditional mortar issues of hollowing and cracking caused by rapid moisture absorption.
