Currently, the search for more efficient, sustainable, and locally adapted construction solutions is crucial for housing development. In this context, this study focuses on the evaluation and optimization of construction systems of joist-vault and joist-slab of expanded polystyrene (EPS), with the aim of improving their mechanical properties and long-term performance. The evaluated solutions use polypropylene synthetic fiber-reinforced concrete (PPRS), which is presented as a promising alternative to steel placed in the floor to withstand shrinkage stresses and temperature changes.
The main result is presented as variants of joist-vault of expanded polystyrene (EPS) and joist-vault construction systems, accompanied by technical and economic recommendations that maximize their efficiency and applicability. This study significantly contributes to the development of more innovative and sustainable construction solutions, improving the strength and durability of structures, and promoting resource optimization in housing construction in Cuba.
