Properties of Foam Concrete Foam concrete\'s salient characteristics include: - Lightweight: Foam concrete has densities that are usually between 300 and 1600 kg/m³, which makes it significantly lighter than regular concrete. This lighter weight reduces structural loads and eases construction. - Thermal Insulation: Excellent thermal insulation is provided by the air bubbles trapped in the concrete matrix, which helps buildings use less energy. - Acoustic Insulation: The cellular structure of foam concrete increases its capacity to absorb sound, enhancing indoor acoustic comfort.
