For the defects of temperature control performance and thermal property of existing concrete building walls, a new composite concrete wall block is proposed, and the thermal property of the block is calculated and analyzed. The transverse hole of designed H-shaped concrete block can be embedded with thermal insulation materials, and the vertical ribs are added to the traditional brick wall, which effectively increases the stability and thermal performance of the wall. The selected PCM concrete has better functions of heat storage and temperature regulation. The thermal performance test results show that the thermal insulation performance of H- shaped wall block is the best, which is due to the H- shaped wall block can effectively block the transverse thermal bridge effect of the wall, and the heat flow increases remarkably. The results of practical environmental monitoring on H-shaped concrete block show that there is a large temperature difference between the external wall and the internal wall, and the wall has better thermal insulation performance.
