北京建工学院研制的联锁式快建空心砌块有炉渣轻质砌块和石屑承重砌块两类。前者经过七年的研究应用，已积累了一定的经验。研究的内容涉及：块型、材料配比、砌块和砌体的物理力学性能、墙体的保温及构造，并编制了用于框架结构填充墙的构造图集和联锁式砌块的生产企业标准等 The interlocking fast building hollow blocks developed by the Beijing Institute of Construction and Engineering have two types of slag lightweight blocks and chip-loading blocks. The former has accumulated some experience after seven years of research and application. The research involved: block type, ratio of materials, physical and mechanical properties of blocks and masonry, thermal insulation and construction of walls, and preparation of a construction atlas for the infill walls of frame structures and production of interlocking blocks. Corporate standards, etc.
