Pick up a dense solid block (approx. 20kg for a standard 100mm block) and a lightweight aerated block (approx. 10kg for the same size).
You cannot discuss blockwork density without discussing grout. density of blockwork
): These blocks, such as autoclaved aerated concrete (AAC), are highly porous. They provide excellent thermal insulation and are easy to handle, though they typically offer lower load-bearing capacity. Medium Dense Blocks ( Pick up a dense solid block (approx
For a hollow wall, the calculation stops at the block weight. For a reinforced wall, you must add the weight of the grout. This calculation is vital for seismic design. In earthquake zones, engineers actually want heavier walls in certain areas to provide base shear resistance, while in other areas, they might want lighter walls to reduce the inertial forces shaking the building. Medium Dense Blocks ( For a hollow wall,
This is the hidden superpower of blockwork density. Fire resistance is measured in "Fire Resistance Ratings" (e.g., 1-hour, 2-hour, 4-hour). The density of the block is the primary variable here.
