Precise blocks are beautiful and energy-saving as self-supporting wall masonry materials due to their precise size and smooth appearance. However, precise blocks have strict requirements for construction, and taking necessary measures to ensure construction quality is crucial for the promotion and application of precise blocks. Based on the characteristics of precision blocks, the construction process and key points of precision blocks are analyzed, and the key points of quality control for precision block walls are summarized. The results show that construction personnel can ensure the construction quality by strictly controlling the quality control points of construction links such as reinforcement planting, masonry, ring beams, lintels, structural columns,and pipeline grooving,so that the advantages of precise blocks in wall applications can be fully utilized,and the promotion and widespread use of precise blocks in construction projects can be promoted.
