DURABILITY AND STRENGTH CHARACTERISTICS OF HIGH-STRENGTH CONCRETE INCORPORATED WITH VOLCANIC PUMICE POWDER AND POLYPROPYLENE FIBERS

Durability and strength characteristics of high-strength concrete incorporated with volcanic pumice powder and polypropylene fibers

In this paper, the partial replacement of volcanic pumice powder (VPP) was investigated for use as a supplementary cementitious material.High-strength concrete (HSC) was prepared using two sets of VPP (10% and 20%) incorporated with three sets of polypropylene fiber (PF) (0.20%, 0.35%, and 0.50%) to produce different concrete mixtures.Several tests
