Blast Furnace Use Dolomite

Jul 06, 2021 Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace. During this continuous process, iron ore or pellets as well as fluxes limestone andor dolomite are heated under reducing conditions in the presence of heated air. Coke and other reducing agents e.g. injected coal are combusted to produce

Influence of blast-furnace slag on behaviour of dolomite

30/09/2015 In this study, influence of blast-furnace slag (BFS) on expansion properties of dolomite was explored. Portland Cement (CEM I 42.5R) was replaced with dolomite up to 40% and blast-furnace slag up to 20%. Hydration heat, setting times, soundness and micro-structures of paste samples and compressive strength and length change of mortar samples were measured. As a result of
