NAMI has developed a novel foam forming technology in cementitious concrete which yields 3 times better thermal insulation than that of normal concrete, eventually lowering the electricity consumption. In addition, this porous-based concrete material is favorable to sound diffusion and contributes to sound insulation. This foamed concrete weighs only 75% of common concrete while yielding the same compressive strength, hence reducing transportation and construction costs. Adopting industrial by-products and wastes in the concrete’s formulation also helps recycle and minimize construction waste.
This NAMI foamed concrete has been awarded the Certificate of Merit under the Hong Kong Green Innovations Awards of the 2014 Hong Kong Awards for Environmental Excellence (HKAEE).
