The size of air bubbles ranges from 0.3 to 0.4 mm. The volume of air is at least 20% of concrete volume. The concrete possesses high flowability, low self-weight, controlled low strength, and excellent thermal insulation. The density of concrete ranges from 400 kg/m3 to 1600 kg/m3 with compressive strength ranging from 1 to 15 Mpa.
