Steel slag powder and GGBFS were from a local iron and steel factory. The steel slag was a type of rotary cylinder steel slag generated from the basic oxygen furnace (BOF) process in this iron and steel factory. The morphology and mineral composition of steel slag were tested by scanning electron microscopy (SEM) and X-ray diffraction (XRD).

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. The degrees …
The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface.
Powder A is based on a crystallised fluorine containing slag consisting of wollastonite (CaSiO 3 ), cuspidine (Ca 4 SiO 7 F 2 ), and small amounts of oldhamite (CaS) besides a residual glassy phase. Quartz (SiO 2 ), fluorite (CaF 2 ), spodumene (LiAlS 2 O 6 ), and several carbon carriers are added secondarily.
Abstract: Slag powder can improve concrete compression strength and durability owing to the activity of volcano ash and powder filling effect when replacing cement as active mineral …
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. The degrees of hydration of slag powders with specific surface area ranging from 300 to 800m 2 /kg were calculated to illustrate the enhancement of pozzolanic effect. As an examination of the …

The slag powder is fine powder after the slag is ground by a vertical mill. According to the different needs of customers, the fineness can be adjusted freely between 200-400 mesh, and the ultra-fine vertical mill can reach more than 1000 mesh fine powder.
Slag, which is usually a mixture of metal oxides and silicon dioxide, is the largest fraction of the by-products of iron smelting. Slag is classified according to its characteristics, and there have been various reports on recycling processes utilizing it [ 1, 2, 3, 4, 5 ].

Slag powder. Reduce the content of Cr6 +. Mixing in cement and adding in commercial concrete have different ways of utilization, which can be summed up in three forms: admixture form, admixture form and main mixing form. The main function is to improve the early strength of cement and concrete and some properties of concrete (such as ...
Abstract: Slag powder can improve concrete compression strength and durability owing to the activity of volcano ash and powder filling effect when replacing cement as active mineral admixture. Test results show that the 28-day strength can reach to 74MPa if slag powder with the fineness 810 m 2 /kg is used to replace 60% cement when making C40 concrete.
The compressive and flexural strengths of ambient-cured alkali-activated slag mortar increased by 22% and 15% respectively, compared to the other mixes up to 0.06% GO addition. This is due to...
