✦ Synopsis

Mechanical properties of Ca(OH) 2 are compared with those of portland cement paste at different por?slties. Intrinsic values of modulus of elasticity (E) and mlcrohardness (H) for Ca(OH) 2 compacts were obtained by extrapolatlng to zero porosity log E and log H versus porosity curves. The values for the Ca(OHI 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 (Kc, Jc, Gc, YT ) were determined. K c and YT versus porosity plots for both systems revealed that these fracture terms are of similar magnitude in the porosity range common to both.

This paper deals with the effect of the leaching process of cement based materials on their mechanical properties. This process induces mainly a total leaching of Ca(OH), and a progressive decalcification of C-S-H which leads to a gradient of C/S ratio in the leaching zone. In a previous work, we ve
