    Abstract：The article mainly studies the influence of fly ash，saw powder and water-resistant reinforcing agent for magnesium oxy-sulfate on modified magnesium oxy-sulfate composite wallboard. The physical properties，sound insulation，thermal insulation，radioactivity，and fire-proof properties of developed modified magnesium oxy-sulfate composite wallboards could meet the requirement of standard JG/T 169—2005 "Light weight panel for building partition wall". The product has advantages of high-strength，fire-proof and light-weight，with a reduction of waste polluting on environment. It is a new product of resource recycling and comprehensive utilization. It belongs to an energy-saving，green and eco-friendly building material，with a broad application prospect.
