The thermal performance of recycled concrete block is studied by orthogonal experimental and the main in-fluence factors on thermal conductivity of recycled concrete is analyzed using range analysis in order to find the influence law of the factors on thermal performance of recycled concrete. The values of various factors are optimized based on the strengths of recycled concrete block, the optimum mix proportion of recycled concrete block with great thermal perfor-mance and relatively high compressive strength is obtained. On this basis, heat transfer performance of recycled concrete block wall is tested. The results show that the thermal performance of recycled concrete block wall is better than that of ordinary wall.
