Slag cement is commonly found in ready-mixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.
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. The results show that the fluidity of the paste containing ...
Compressive strength of blast furnace slag concrete with different dosage of slag was studied as a partial replacement of cement. From the experimental investigations, it has been observed that, the optimum replacement of Ground Granulated Blast Furnace Slag Powder to cement without changing much the compressive strength is 15%.
This study aimed to examine the properties of self-compacting concrete (SCC) developed using eggshell powder (ESP) and granulated ground blast furnace slag (GGBFS) as partial cement replacement. The coarse aggregate impact value was 21.6% and the water absorption of the fine aggregates was 24 wt%. 10 wt% partial replacement was optimal for flow ...
This rapid cooling, called quenching, creates glassy granules, which are then ground into the fine powder known as slag cement. Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s.
is a cementitious replacement material that has been used in United States concrete design since the early 1900s (Slag Cement Association, 2002). Slag cement is a byproduct of the iron-making process and is composed primarily of silica and calcium.
When the cement replacement ratio is 20%, the fluidity of paste containing steel slag powder is approximately 25 mm higher than that of paste without steel slag powder. These results indicate that using steel slag powder as a mineral admixture could improve the fluidity of paste, which is beneficial for the workability of concrete.
Concrete property can be maintained with advanced mineral admixtures such as blast furnace slag powder as partial replacement of cement 5 to 30%. Compressive strength of blast furnace slag concrete with different dosage of slag was studied as a partial replacement of cement.

It is considered that the use of ferronickel slag powder in the mortar or concrete can be effective in reducing drying shrinkage. Figure 11 shows the drying shrinkage of the ternary mortar using two types of cementitious materials, including ferronickel slag powder, blast-furnace slag powder, and fly …
Jun 15, 2020· A large number of studies have shown that the chemical composition of steel slag is similar to that of cement, and researchers believe that a promising way to reuse steel slag powder (SSP) is by replacing the cement in concrete with it, which could improve the workability, decrease its hydration heat, fill the internal micropores, and enhance its interfacial bond.
May 09, 2018· The concrete made with Ground Granulated Blast Furnace Slag cement sets more slowly compared to ordinary Portland cement concrete based on the amount of GGBS in the cementations material. It also needs longer period to gain required strength. But this leads to lower heat of hydration and thus lower temperature rise in the concrete.
Using slag powder in concrete, not only can solve the piled slag powder problem in Baotou area, but also can save resources and energy and improve concrete performance, resulting in huge economic benefits. The results showed that slag powder can increase concrete mobility.
Ground granulated blast-furnace slag (GGBFS) Our slag cement CEMSlag TM is a hydraulic cement material created when granulated blast-furnace slag from the steel manufacturing process is ground to a fineness suited for concrete production. Environmentally friendly and reduced greenhouse gas emissions
WHAT IS GGBS. GGBS is a high performance alternative to traditional cement that will increase the technical performance of your application, improve its appearance and minimize its environmental impact.. GGBS is an acronym for Ground Granulated Blast Furnace Slag, a by-product from the manufacture of Iron.GGBS is used in combination with Portland cement to produce superior longer lasting concrete.
