CHARACTERISTICS

1. Lighter Weight — red brick 2,000 kg/m³, AAC block 600 kg/m³.
2. More Environmentally Friendly — reduces waste by 30%, emissions by up to 50%.
3. Heat Resistant — porous material aids cooling and fire resistance.
4. Long-Lasting — doesn’t degrade under normal weather.
5. Consistent Sizing — factory standardized, commonly 60x20x7.5 cm.

What to Consider

1. Quantity Needed — measure and calculate requirements first.
2. Bonding Pattern — proper bond to strengthen the wall.
3. Using the Right Mortar — use a notched trowel (RK-201) for consistent, efficient results and to prevent popping.
