Durability of Different UHPFRCs, Made from Pozzolan as a Substitute for Portland Cement and Immersed in Two Aggressive Environments of Hydrochloric and Sulfuric Acids


Cite

The objective of this study is to evaluate the effect of pozzolan on the durability of high-performance fiber concretes in two aggressive environments. For this, prismatic test pieces were made at (0%, 10%, 20%, and 40%) of pozzolan and immersed in two acids, hydrochloric and sulfuric. Then characterizations were carried out, such as the loss of mass, the depth of degradation and the mechanical resistance. The results obtained show that with the substitution rate of pozzolan, the loss of mass and the depth of degradation increase in the two acids, while the mechanical strength increases in hydrochloric acid and decreases in sulfuric acid.
