Foam Concrete Density

foam concrete density is the amount of aggregate and foam that is in a foam concrete mix.

There are several different ways to make foam concrete, ranging from using a ready-mix truck to producing it in your home.

The most common way is to use a foaming agent that is mixed with base material in a truck mixer. The resulting mix is then pumped through a foaming machine to produce the desired foam concrete density.

Alternatively, a method called dry injection is used to produce foam concrete from dry materials. This technique involves weighing the dry materials correctly in onboard silos and then feeding them into a series of static inline mixers, where they are mixed with a continual on board density monitor to ensure the blending process is correct.

In addition to the dry density, foam concrete has a wide range of physical properties that are dependent on the various admixtures, aggregate types and foaming agents. These include shrinkage, strength to weight ratio, fire resistance and thermal properties.

The mechanical properties of foam concrete are generally comparable with ordinary concrete. The compressive strength is typically greater than 0.2 N/mm2 and can reach up to 10 N/mm2 depending on the type of foaming agent used, the type of cementitious content and other supplementary cementitious materials. Similarly, the modulus of elasticity and flexural strength can be higher than those of ordinary concrete. These properties make foam concrete multi-functional and versatile, which makes it a valuable construction solution in many different applications.
