Mechanical and Structural Behavior of Concrete Blocks with Granulated Polystyrene (PS) and Recycled Polypropylene (PP) Fibres and Their Use in Low and Medium Height Frames

ABSTRACT

This research proposes to include different percentages of recycled polypropylene (PP) fibers and polystyrene (PS) granules in the manufacture of concrete blocks. They are thermoplastic materials widely used in industry and are characterized by their lightness, their low thermal and electrical conductivity, and their low humidity absorption coefficient, factors that improve the efficiency of constructions. The results of this study show improvements in the mechanical behavior of the blocks with these plastic additives compared to the traditional ones, along with improvements in the structural behavior of the low (2-story) and medium-height (8-story) frames.
