Abstract

Abstract

In this study, fly ash-slag-based cementitious materials were prepared from fly ash co-metallurgical solid wastes (blast furnace slag, steel slag, and desulfurization gypsum) instead of cement, as backfilling materials for the mining area, and the effect of fly ash incorporation on the hydration mechanism and heavy metal stabilization effect of the cementitious system was investigated. The results showed that a low amount of fly ash (10%) in the cementitious system would inhibit the generation of hydration products in the early stage (within 3 days) of the system and reduce the compressive strength of the cured body; the alkali excitation effect of fly ash would promote the generation of hydration products, calcium alumina to a certain extent, with a facilitating effect on the compressive strength of the cured body at the end of maintenance (the 28 th day); high amount of fly ash in the cementing system (25%) would seriously inhibit the hydration process of the cementing system, but the compressive strength of the product was still higher than the requirements of the cementing material for mining area. On the other hand, the fly ash-slag-based cementitious system stabilized the heavy metals in the fly ash well, and the leaching of heavy metals in all other treatment groups (with fly ash addition of 0%~20%) satisfied the standard limits, except for the Zn in the treatment group with fly ash admixture of 25%, which was close to the China national standard limit of cementitious sand (GB/T 30810—2014). Therefore, using fly ash as mine backfilling cementitious material is an ideal method,under the appropriate admixture amount.
- MSWI fly ash,
- metallurgical solid waste,
- solidification/stabilization,
- cementation backfilling,
- heavy metals
