| Abstract: |
| In order to obtain new desulfurization gypsum block material which have lightweight and high strength, with desulfurized gypsum as raw material,to study new gypsum block apparent density, fracture load, compressive strength, softening coefficient, water absorption rate changes by adding expanded perlite, glass fiber and water proofing agent. The results show that the optimal ratio is 1.25% expanded perlite, 1.4% glass fiber content, 2% waterproof agent, at this time the gypsum apparent optimal density and mechanical properties achieve optimal value. the preparation of the apparent density of 953kg/m3 brick under this condition, the fracture load is 2730N, the compressive strength is 10.6MPa. |
