Hydration behavior of cementitious materials with all solid waste based of steel slag and blast furnace slag

Xiaowei Cui

Abstract


Cementitious materials was prepared with steel slag powder (SS), blast furnace slag (BFS) and desulfurization gypsum (DG). The influence of proportion of SS on the strength of the concrete with industrial solid wastes was studied. Changing rules of pH and representative concentration of the ions were explored. The results showed that when the mass ratio of SS, BFS and DG is m(SS): m(BFS): m(DG)= 30:58:12, the concrete with industrial solid wastes possesses a bettercompressive strength at 3d, 7d and 28d. With the increasing dosage of SS, pH and ion concentration of Ca2+ decreased first and then increased. The concentration of silicon (aluminum) solutes were relatively low and increased after later. The SS and BFS can promote the hydration of each other under the effect of DG and the major hydration products are ettringite (AFt) and Calcium silicate hydrate (C-S-H) gels.
