ANALYSIS OF HOLLOW-CORE SLAB ALVEOLAR SHAPES AND THEIR IMPACT ON NOISE PROPAGATION

Abstract

The demand for lighter and more efficient construction solutions has driven the use of hollow-core slabs in buildings. Despite their practicality on-site, these structures still face limitations in sound insulation. This study analyzes how the geometry of the cores influences the acoustic and structural performance of concrete slabs, based on national and international standards. Geometric models were developed in AutoCAD, and laboratory, destructive, and acoustic tests were conducted under controlled environmental conditions. Statistical analysis confirmed that geometric adjustments can improve both sound insulation and structural efficiency, enhancing the applicability of hollow-core slabs in modern constructions
