A Nanoindentation Study of Portland Cement Pastes Exposed to a Decalcifying Environment
The effect of decalcification on the micromechanical properties of cement pastes was investigated using nanoindentation coupled with statistical methods. Portland cement pastes were subjected to accelerated decalcification via exposure to ammonium nitrate solution for 125 days. A grid nanoindentation technique was performed in the degraded zones found in the cement paste cross-section to evaluate the differences in the local mechanical properties. Results showed that while the hardness and modulus values decreased as a function of the extent of degradation, the rate of decrease was influenced by the cement phases present.
