Problem addressed
Traditional normal concrete is heavy and requires higher cost for transportation and strong foundation. NAMI’s high strength lightweight concrete shows lower density, which can save the material consumption and transportation efforts, as well as reduce the weight of superstructure and hence the size of foundation.
Innovation
- Taking advantage of the advanced material technology, NAMI's high strength lightweight concrete is composed of high performance cementitious paste and air voids with controlled size, showing high strength to density ratio and superior stability, suitable for production of precast building elements.
- NAMI’s high strength lightweight concrete can reach a strength level of grade C25 at a density of 1500kg/m3.
- It also shows superior thermal insulation and sound absorption properties, saving the energy consumption by air conditioning, as well as enhancing the indoor environment quality and fire resistance.
Key impact
- Compressive strength: 30MPa at a density of 1,500kg/m3
- Fire resistance: > 90mins (80mm thick wall panel); > 165mins (125mm slab panel under loading)
- Acoustic insulation: >STC42 (80mm thick wall panel)
- Heavyweight anchorage capacity: 4000N (80mm thick panel)
Application
- Structural slab panel
- Structural and non-structural wall panel
- Protection cover for steel structure
- Fire rated door
