In this work, different one-way slab solutions have been studied for a reference building, with spans from 5 to 10 meters, based on the most frequent uses in building in terms of material quantities, and environmental criteria based on CO2 emissions generated during production. We have been able to evaluate the different systems and how post-tensioning slabs allow for optimization of material resources. The current status of low production of post-tensioning flat slabs is actually related to a combination of reasons such as lack of technical knowledge, developments in currents codes in each country resulting in higher material consumption, or inertia in the workplace with resistance to changing systems which are apparently satisfactory. But above all, it is necessary to introduce sustainability criteria in construction based on reducing CO2 emissions and also on a more responsible consumption of raw materials.
