cellular foam concrete is a lightweight material, typically weighing half as much as similar materials. It has a low density, high compressive strength, elasticity, good thermal insulation, & acoustic absorption properties.
Generally, cellular foam concrete is a type of controlled low strength material (CLSM), which has uniformly distributed air bubbles instead of sand and stone aggregate. This reduces unit weight significantly, while also enabling it to be more consistent.
The primary differences between cellular foam concrete and other lightweight cementitious materials are the processes used to create the air within the material, and the equipment required to produce it. Probably the closest material to cellular foam concrete is aerated autoclaved concrete (AAC), which uses a chemical reaction within the slurry itself to generate air voids for density reduction.
There are many different types of cellular foam concrete, and each one has its own advantages. However, the most important characteristic of cellular foam concrete is that it has a self-compacting property, meaning no compaction is needed and it easily flows out from the pump to fill the mold.
Another feature of cellular foam concrete is that it can be pumped thousands of feet without deterioration. This facilitates groundwater recharge, & makes it a highly sustainable building material.
CJGeo has generated and placed hundreds of thousands of cubic yards of cellular foam concrete, so we can help you decide if it is the right choice for your project. From constructibility reviews to budgetary estimating, and consultation with our in-house Geotech/M&T PE, we’re happy to assist you.
