Mechanical and Durability Properties of High-Performance Concrete Incorporating Fibers and Algerian Natural Pozzolans in Chloride Attack

This study aims to assess the effect of sodium chloride attack on mechanical and durability properties high-performance concrete (HPC) based fibers natural pozzolans. The resistance specimens against chemical is determined by unit weight, compressive strength, splitting-tensile ion permeability, apparent gas visual inspection after 28, 90, 180, 365 days testing. A total three types are assessed: reference (RC), HPC, fiber-reinforced (HPFRC) stored in tap water aggressive (i.e., a 10% NaCl solution). test results demonstrate that presence negatively affects permeability HPC. However, HPC HPFRC remain stable not influenced solution compared RC. pozzolans attenuate side occupying voids filler effect) generating denser products pozzolanic reaction) cement matrix.
