On the Experimental Methods for the Determination of Elastic Modulus and Hardness of Cement Particles by Nanoindentation

Abstract:

Article Preview

The elastic modulus (E) and hardness (H) of the cement particles that embedded in different subbases (namely epoxy resin and hardened cement pastes with different ages) were measured by nanoindentation. The results indicate that the measured values of E and H of the cement particles encased in resins are smaller than normal values, while the measured values of cement particles embedded in hardened cement pastes are closely related to the hydration degree of subbase cement pastes. As nanoindentation measurement of cement particles is significantly affected by the hardness of the subbase, the test of E and H of cement particles should be carried out based upon a rather hard substrate.
