Abstract :
[en] The feasibility of using waste brick powder (WBP) in the manufacture of self-compacting mortar has been investigated in this study. The limestone filler was partially or totally (0%, 50% and 100%) substituted with WBP. The rheological properties, compressive and flexural strengths, drying shrinkage and durability properties (including carbonation resistance, chloride ion diffusion and sulphate resistance) of self-compacting mortars were evaluated. The WBP-mortars presented a higher yield stress and plastic viscosity than that of WBP-free mortar: the additional water has to be added in order to achieve the equivalent workability. The compressive strength of WBP-mortars slightly decreased after 7 days, but the decreasing trend seemed to be compensated by the pozzolanic activity of WBP and remained equivalent after 28 days. The substitution of limestone filler by WBP didn’t seem to impair the durability behavior of mortars (except for the resistance to carbonation). Therefore, it is possible to manufacture self-compacting mortar by partially or totally substituting limestone filler by WBP.
