Abstract

The current work examines the flexural behavioral analysis of structural lightweight concrete (SLWC) beams made of expanded clay aggregate (ECA) and its conclusions. Polypropylene (PP) fiber is used in these beams. The investigation took into account a total of six beams, of which one specimen was constructed using regular-weight concrete and the other using SLWC with 20% ECA in place of coarse aggregate. The remaining four beams were constructed using SLWC material with an ECA base that included polypropylene fiber in volume fractions of 0.1%, 0.2%, 0.3%, and 0.4%. Each beam underwent testing in a loading frame up to 4-point bending.


Keywords: Expanded clay aggregate, Polypropylene fiber, Deflection, Ductility, Strength.
