Foam concrete weighs up to 80% less than normal concrete. This makes it ideal for a variety of applications, including filling post holes and sealing cracks. It also has excellent insulation, sound-absorbing and fire-resistant properties.
Weight reduction is due to the presence of large air bubbles that form when foaming agents and water are pumped into a foaming machine. These air bubbles have a diameter ranging from 0.1 to 1 mm and are evenly distributed throughout the concrete.
The size and density of these air bubbles determines the strength of foam concrete. The compressive strength of foamed concrete is higher than that of standard concrete.
Foam concrete is an excellent solution for a wide range of applications, from highways and commercial buildings to disaster rehabilitation facilities. Its lightweight properties make it easy to transport and move, and its durability makes it suitable for long-term use.
Foam concrete consists of up to 80 percent air, which means it’s much cheaper to produce than normal concrete. Its low density also allows it to be used in areas where standard concrete is too heavy, such as in the middle of a highway.
Foamed concrete is a good choice for fire-proof constructions, as it can resist heat up to 12000C. In tests carried out in Australia, a 150mm wide panel of foamed concrete remained protected from fire for four hours.
Foamed concrete is also easy to pump, which makes it a convenient way to deliver large volumes of the product. However, it’s important to ensure the correct mix ratios are used to ensure its strength.
