Abstract: The effect of decalcification on the physical, mechanical (compressive and splitting tensile strengths) and microstructural properties of carbon microfiber (CF) reinforced cement-based materials was studied. Exposure to ammonium nitrate solution was used to accelerate decalcification. The CFs were added to Portland cement (PC) pastes at a loading of 0.5% per weight of cement. The mass loss of the cement pastes, penetration depths of ammonium nitrate into the pastes, and change in strengths were measured. Results indicated that the presence of the CFs affected the alteration of the mechanical properties of the PC paste.
