This research was carried out in the city of Trujillo, with the objective of determining the influence of EPS beads on the slump, unit weight and compressive strength in concrete for lightened slabs. The aggregates were characterized and, in compliance with the Peruvian technical standards in force, the mix design was carried out according to ACI 211 method, using expanded polystyrene beads with a density of 11.21 kg/m3. The percentage amounts of EPS beads to replace the fine aggregate are 5%, 10% and 15% according to their volume. After mixing the materials according to the regulations, specimens measuring 20 cm high and 10 cm wide were prepared with the different dosages indicated, in addition to the standard concrete. The fresh concrete was tested for slump and unit weight according to NTP 339.035 and NTP 339.046, respectively, and the hardened concrete was tested for compressive strength according to NTP 339.034. The values of the average slump of the concrete for the standard concrete had a value of 4.00 inches, for the concretes with EPS beads the higher the quantity the slump is also proportional, the unit weight of the standard concrete with a value of 2444 kg/m3, and its decrease is notorious, according to the higher percentage of EPS beads in substitution to sand, being reduced up to 3.76 % with respect to the standard concrete for the design with 15 %. Regarding the compressive strength, there was a positive trend as the higher the percentage of EPS beads in the mix, the higher its strength, 28 days after its elaboration, in the concrete with 15% addition, an average compressive strength of 263 kg/cm2 was obtained, thus obtaining the maximum strength of all the mix designs elaborated.
