Mechanical properties of Ca(OH)[2] are compared with those of portland cement paste at different porosities. Intrinsic values of modulus of elasticity (E) and microhardness (H) for Ca(OH)[2] compacts were obtained by extrapolating to zero porosity log E and log H versus porosity curves. The values for the Ca(OH)[2] and portland cement paste systems are of similar magnitude. Flexural strength values for both systems were also determined to be of similar magnitude for the porosity range studied. Fracture terms (K[c], J[c], G[ c], gamma [T]) were determined. K[c] and gamma [T] versus porosity plots for both systems revealed that these fracture terms are of similar magnitude in the porosity range common to both.Les caract\ue9ristiques m\ue9cani...
