A novel approach for preparing ceramisite using loess as the raw material and fly ash floating beads as the pore-forming template was put forward. The effects of particle size and quantity of fly ash floating beads on the structure and properties of ceramisite were investigated. The results show that the pore structure of ceramisite can be constructed and regulated by adjusting the size and amount of the beads during the preparation stage of ceramisite green bodies.The obtained sintered loess ceramisite achieves a balance between low density， high strength， and low water absorption rate， surpassing all performance standards outlined in GB/T 17431.1—2010 Lightweight Aggregates and Its Test Methods Part 1： Lightweight Aggregates.
