A novel LF refining slag contains K 2 O has been developed in order to produce ultraclean saw wire steels. The diameter of ultrafine saw wire is between 50×10 −6 m (50 µm) and 80 ×10 −6 m (80 µm), any hard inclusion which diameter more than 5×10 −6 m (5 µm) should be avoided because it probably will cause wire breaking. In order to enhance inclusion removal in C96V …
Read OnApplication of high-volume slag based geopolymer mortar is often confined to usage in controlled environments due to its limited flexibility in controlling the setting time. The main aim of the study is to regulate the fast setting of Ultrafine blast furnace slag (UBFS)-based geopolymer mortar (GM) by utilizing mineral admixture.
Read OnApplications Ultrafine binders are mainly used for sta-b i nona i t a liz d/or waterproofing of soils where standard cements are not applicable due to their grain size. Ultrafine binders have significantly extended the range of soils being groutable with cements. Nowa-days, soils with 80% of fine sand are groutable with suitable ultrafine binders.

HNP-1500, the extreme ultrafine-grain grout, has an average particle size of 1.5 µm. As shown in Fig. 3, the smaller the average particle size of the cement, the wider the scope for the application of the cement.6) For
Read OnUltrafine Alkali Activated Slag (AAS) and Portland/Slag (P/S) cements have been commercially available in the United States for 2 and 5 years, respectively. Ultrafine cements have been the subject of research at Northwestern University for 6 years.Particle size of the ultrafine slag cement is characterized by 98% passing at 7 microns and a D50 at 3 microns in …
Read OnUnlike other micro fine materials, ultrafine slag has the major two components (CaO, SiO 2). This enables the latent hydraulic properties in these materials. This can be represented as below: Fig. 2: Ultrafine Slag Composition Because of the combined qualities (fineness + PSD + dual reaction), ultrafine slag holds a bright future.

Nowadays high strength concrete generally made with Ordinary Portland Cement. In this investigation Portland Pozzolana Cement (PPC) Fly ash based was used to make concrete more environmental friendly. In this experiment five mixes were prepared in …
Read OnLittle or no crystallization occurs when the slag is cooled and rapidly quenched to a glassy state. This process produces sand-sized (or fleet-like) fragments, often with some fragile clinker. At this point, the particle size of slag is mostly <5mm. With the use of the ball mill, the granular slag can be processed into ultrafine slag powder.
