Steel slag is generally regarded as a supplementary cementitious material in cement-based materials, which is conducive to the realization of the goal of carbon peak and carbon neutralization. However, the lower cementitious activity and poorer volume stability of steel slag limit its high dosage in cement-based materials. In this paper, steel slag ultrafine …
From Table 4, it was seen that carbon emissions of common slag were 40 kg CO 2-e/t, while that of superfine slag with D50 = 3.71 μm were 75 kg CO 2-e/t due to the superfine treatment [38]. MP was a waste generated by marble processing and quarrying industry, whose carbon emissions were not considered.

The GGBS in this work was commercially available ultra-fine slag of two sizes (V1 and V2), Nitrogen BET Surface area of V2 (3955 m 2 kg −1) was found to be much higher than the V1 (2435 m 2 kg −1).The (CaO + MgO)/SiO 2 ratio by mass (M, coefficient of basicity) was a reliable indicator of reactivity [25], Calculated M = 1.55 of …
A slag grinding plant is also referred to as a slag grinding unit or a GGBS grinding unit.As its name indicates, the plant aims at producing ground granulated blast furnace slag, a fine powder with a specific fineness (marked as a specific surface area).The finished GGBS powder is a substitution for part of conventional Portland cement used in concrete …
Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays a critical role in the production of high-quality crude steel, although its behavior inside the BOS vessel (formation and reaction with metal droplets and gas) is still not clear and its recycling has always been challenging.
In general, the slag powder is processed by the slag grinding plant in advance, and slag powder will be sent into the cement plant for making slag cement, ... Mixing with superfine powder such as slag improves the compactness of concrete and cement products, and its later strength is high, which reduces the cost of concrete and cement …
The particle size distribution (PSD) of the dense packing powder and that of actual cement powder was analyzed to explain the packing effect of superfine powder.
