摘要
TECHNICAL FIELD The present invention relates to a steelmaking slag and a stabilizing agent for soft ground improvement using recycled resources through a sorting process. The present invention relates to a method for producing a cement composition, which comprises 20 to 40% by weight of a fine powder of a converter steelmaking slag in which a residual iron component is reduced and a lime component is increased due to no magnetic force during magnetic force sorting, 0 to 30% by weight of F grade fly ash, 0 to 7% by weight of desulfurized gypsum, 40 to 70% by weight of an alkali activator, and 0 to 0.5% by weight of an alkali activator; In the stabilizing agent for soft ground improvement wherein the coastal soft ground made of marine clay is solidified, the above-mentioned converter steel slag fine powder is recovered by a magnetic separator having a magnetic force of 1,500 to 2,000 Gauss and a rotating speed of 9 to 53 RPM of the separator The XRD analysis showed that the CaO content was 33% or more, and that the calcium silicate (CS) content and the calcium (CF) content were 75% or more as a result of XRD analysis. As a result, it is possible to produce a heavy metal stabilizer for the treatment of soil and mine wastes, which is produced by the magnetic force selection process of the steel making slag, Can be used as cement admixture to effectively solidify the coastal soft ground consisting of sediment and marine clay.
