Abstract：The steady-state thermal transmission performance and influencing factors of sintered porous brick,sintered hollow brick and sintered insulation brick in Jiangxi Province were studied by hot box method. The results show that the heat transfer co-efficient of sintered porous brick is 1.99~2.43 W/(m2·K)(190 wall),the heat transfer coefficient of sintered hollow brick is 1.81~2.18 W/(m2·K)(190 wall),and the heat transfer coefficient of sintered insulation brick is 1.20~1.58 W/(m2·K)(240 wall). The ther-mal conductivity of the substrate was measured by the transient hot-wire method. The influence of hole structure and wall moisture condition on thermal performance was studied. To the same wall,heat transfer coefficient of absolutely dry wall can be reduced by 12.7% than that of the wet wall.
