![]() ![]() Good agreements in values of heat transfer coefficient existed by using the test, theoretical computation and ANSYS (ANSYS Inc. With the plastering surfaces, the heat transfer coefficient reduced by 4.4% to 8.9%. The tested heat transfer coefficient of AAC self-insulation block masonry with thickness of 250 mm without plastering surfaces was (0.558 ± 0.003) W/(m 2 The stress–strain relationship of masonry in compression could be predicted by the similar expression of conventional block masonry. The compressive strength of masonry was related with the block and mortar strengths, the shear strength of masonry along mortar joints was related with the mortar strength. Compared to those with larger thickness of insulation mortar joints, the masonry with thin-layer mortar joints had better compressive performance and lower shear strength. The distinctive feature of the blocks and mortars is the lower thermal conductivity with expected strength. Different kinds of joints and the plastering surface were used to build the masonry specimens. This paper performed a detailed study on the fundamental properties and thermal conductivity of autoclaved aerated concrete (AAC) self-insulation block, and the mechanical properties and heat transfer resistance of the AAC self-insulation block masonry.
