Effect of Fly Ash on Thermal and Mechanical Properties of Expanded Perlite Insulation Product

Abstract:

Expanded perlite insulation samples were prepared with expanded perlite as aggregate, aluminum dihydrogen phosphate as binder and fly ash as addition by mixing, molding, drying and calcination. The effects of fly ash mass percentage on the compressive strength, thermal conductivity, moisture content and density of the samples were studied. The results indicated that the combination properties of adding 10 % fly ash were the best among the all samples according to the national standards (GB/T10303-2001) No 350 Qualified of expanded perlite insulation products. Its compressive strength, thermal conductivity, moisture content and density were 0.456 Mpa, 0.08165 W/ (m K), 0.02 mass % and 259 kg/m3, respectively.
