Abstract：
The new slab is filled with EPS-block, and the main component of EPS-block is disused expanded polystyrene foams. EPS-block is made into centrosymmetric torus to be applicable for being filled into two-way slabs, and to be good for concrete flow. Anti-float measures for EPS-blocks are prior to be made, and the concrete's compacted density at the bottom of EPS-blocks is assured, thereafter, concrete is cased once. Construction quality is guaranteed accordingly.
