Mg(OH)_2-based desulfurization absorbent has been successfully prepared from the alkaline iron slag in the laboratory for the first time,and the flue gas desulfurization(FGD) was researched through a simulated experimental set-up.

The research progress of chemical admixture for alkali-activated slag cement and concrete;

In this paper,the effects of all kinds of alkalis on strength of alkali-activated slag-fly ash concrete,and the effects of different addition amounts of fly ash on strength of alkali-activated slag concrete,and acid resistance performance of the concrete have mainly studied.

Many research achievement have been acquired mainly on the studies of activator, durability and setting time of alkali-activated slag cement and concrete.

Complex activator for alkali slag test researching;

Study on a series of contrast test including simply using water glass as excitant and adopting complex excitant of water glass-potassium carbonate-sodium hydroxide to excite or complex excite alkali slag cementing material indicates that complex excitant has favorable excitation effect.

With the development of iron and steel industry, discharged amount of steel slag and pyrite slag is increased every year.

Study on the preparation of PFS from iron-rich slag and concentrated sulfuric acid;
