Concrete double-K fracture toughness and fracture energy influenced by porosity and pore size

Abstract The diameter and quantity of internal pores in concrete significantly influence its mechanical properties. While existing studies predominantly focus on the influence of pore quantity, this study utilizes pre-fabricated pores made from polystyrene particles (EPS) to investigate the effects...
