From among the several types of slabs, there is uncertainty about most cost-effective one for structures with short, medium, and long spans. A study comparing cost solid, flat, hollow block (HB), post-tensioned (PT) slabs 4, 6, 8m spans was conducted using SAFE software. For each span length, total quantities concrete steel bars were found compared 4 slabs. Then, bars, concrete, blocks, tendons...
