Substitution of limestone filler by waste brick powder in self-compacting mortars: Properties and durability

The feasibility of using waste brick powder (WBP) in the manufacture self-compacting mortar has been investigated this study. limestone filler was partially or totally (0%, 50% and 100%) substituted with WBP. rheological properties, compressive flexural strengths, drying shrinkage durability properties (including carbonation resistance, chloride ion diffusion sulphate resistance) mortars were evaluated. WBP-mortars presented a higher yield stress plastic viscosity than that WBP-free mortar: additional water to be added order achieve equivalent workability. strength slightly decreased after 7 days (the series M ? BP 5.6% 9.3% for 100% WBP based comparing reference mortar, respectively; while similar workability M-BP100WA which on 16.7% it could 26.8 MPa), but decreasing trend seemed compensated by pozzolanic activity remained 28 5.3% 35.6 MPa). substitution didn't seem impair behavior (except resistance carbonation). Therefore, is possible substituting
