Ultra-lightweight foam concrete (ULFC) is a relatively new construction material that has gained attention recently due to its unique properties. This not very heavy and low-density, making it easy form into different shapes sizes. Its excellent thermal insulation makes popular for building walls, roofs, floors. review paper provides an in-depth examination of the properties characteristics ULFC. composition typically consists cement, water, foam, additives, various manufacturing methods used produce it—the mechanical ULFC, including compressive strength. The density ULFC can vary greatly, usually falling between 100 600 kg/m3. diversity this be affected by factors, such as kind number additives applied foaming thickening employed. highlights applications in industry. use TC material, which help reduce heating cooling costs; structural dead loads structures. also discusses challenges associated with production, stability. Foam emits 302–508 kg CO2 per cubic meter, primarily Portland but enhances energy efficiency, reducing household emissions, while advanced recycled materials offer superior acoustic lower environmental impact. Additionally, we examine current research on suggest potential avenues future investigation. aims introduce put forward range cutting-edge original recommendations informative guidelines, ultimate objective directing shaping endeavors focus effectively exploiting utilizing ultra-light foamed concrete.

Carbon nanotube foam concrete (CNFC) is a low-carbon and sustainable lightweight backfill material. In this paper, the cracking evolution characteristics damage patterns of CNFC during uniaxial compression were monitored by acoustic emission (AE) technique, microscopic pore structure was analyzed fractal theory. The results demonstrated that flowability within 163–176 mm, respectively. With 0.05 wt.% carbon nanotubes (CNT), 7d 28d compressive strengths (FC) increased 33.04% 27.74%, microstructural observation revealed CNT can improve stability optimize spatial distribution size. AE responses reflected excellent bridging effect effectively suppressed crack development enhanced performance FC. cost from 169.78 RMB/m 3 to 423.72 . per unit intensity CNFC0.05 17.44% CO 2 decreased 21.69%. are expected provide reference for preparation research nanocomposite concrete.
