"WebIf the longer span of the slab is l y and the shorter span is l x, then for a two-way slab, l y /l x is less than 2. If the ratio is greater than 2, it is identified as a one-way slab. The two-way slabs distribute the loads in both directions. Hence, the reinforcement is provided along shorter and longer sides of the slabs. " - Two way post tension slab design

WebA post tensioned slab can be identified by the grouting of the live stressing end of the cables. Once the cables are tensioned and grouted, the live ends where the jack applies the stressing is also grouted. The grouting is usually a different mix to the concrete slab itself so usually has a different colour.
