Comparative Study of Destructive and Non-Destructive Test on Lightweight Concrete Using Expanded Polystyrene

Abstract: One practical way to lessen the weight of big, massive structures in modern construction is to employ lightweight concrete. This technique substitutes lighter materials that yet offer high-strength construction components for conventional coarse aggregates. This study produced a concrete mix that retained the same volume as traditional dense concrete by substituting expanded polystyrene (EPS) beads for coarse particles. A water-to-cement ratio of 0.56 was maintained while 15% to 20% of the coarse aggregate was replaced with EPS beads to create the M20 grade mix. The specimens were cast with a normal 150 x 150 mm dimension.Density and compressive strength exhibit a strong correlation. Specifically, as density decreases, there is a noticeable decline in compressive strength. After 14 days, the material demonstrates a compressive strength of 16.29 MPa. The study examines density values ranging from 2340 to 2044 kg/m³, with corresponding compressive strength measurements after 28 days falling between 26.37 MPa and 17.77 MPa..Destructive tests revealed greater compressive strength than non-destructive tests, according to the data. When up to 15% of the coarse aggregate in the M20 mix was substituted with EPS beads, the greatest compressive strength was noted
