Chemo-mechanical properties of alkali-activated slag/fly ash paste incorporating white mud

White mud (WM) is a waste solid from paper industry. It mainly contains calcium carbonate and residual alkali metal ions (e.g., K+, Na+ and Mg2+). The aim of the study was to test the feasibility of incorporation white mud into a blended slag/fly ash alkali activated binder system. Blends of slag and fly ash was used as the precursor and WM was used as the filling material. Pastes with 0%, 10%, 20%, 30%, 40% and 50% WM were prepared for the...
