It is mentioned previously that the reactivity of slag is influenced by its fineness of grinding (specific surface area) that is determined by the sizes of slag particles. The finer the slag particles, the larger the surface area, which means higher hydration degree of slag.

Steel slag, FA, and cement exhibit distinct specific gravities: 2.81 for steel slag, 2.32 for FA, and 3.15 for cement. Additionally, their specific surface area values differ: steel slag has a specific surface area of 670 m 2 /kg, FA has 478 m 2 /kg, and cement has 311 m 2 /kg. The mineral composition of steel slag and FA is shown in …

Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable concrete. The secondary pozzolanic reactions can result in reduced pore connectivity; therefore, replacing partial amount of Portland cement (PC) with GGBS can significantly reduce the risk of sulfate attack, alkali–silica reactions and …

The experimental results show that the influence of steel slag powder on water requirement of normal consistency of cement is in relation to its specific surface area, and the value of decreases for steel slag powder with a lower-specific surface area while increases with a higher-specific surface area. The partial replacement of cement …

The specific surface area of NS and manufactured sands was approximately the single digits (m 2 /kg) while the specific surface area of stone powders was several hundreds or thousands (m 2 /kg) [34] [35]. The surface area provided by particles was hundreds of times less than that provided by stone powders.

Figure 3 shows that the SSAs of cement, 3%S+B, 8%S+B, C+3%S+B, and C+8%S+B, do not increase linearly with the grinding time, but decrease after an initial increase with a notable peak value. The SSA of cement increased after the first 30 min from 1.575 to 1.867 m2/g, and decreased to …
