摘要: Abstract Building energy consumption and industrial solid wastes have attracted great concerns in recent years. A novel thermal insulation composite (NTIC) is prepared by combining with expanded polystyrene (EPS) beads for non-structural applications of building conservation. Industrial waste containing flue gas desulfurization (FGD) gypsum improves the fire resistance NTIC samples reduces carbon footprint material as compared similar composites based on portland cement. In order to substantially reduce density conductivity samples, proportion should be decreased. However, significant quantities large voids appear which leads difficulty shaping sharp decrease mechanical properties. Compression method was used solve above problem this paper. The morphological characterization, physico-mechanical properties, water absorption, behavior different compression ratios were studied. results showed that density, absorption gradually decreased increase EPS content. a ratio 1.8 possessed preferable properties lower than those 1.4 case approximately same due many inside latter. mainly determined their density. There no combustion all under flame, illustrated NTICs paper superior safety.
