SSA concrete or slag cement concrete shows lower resistance to acid and salt corrosion (Palankar et al., 2016). When exposed to SO 4 −2 environment, SSA showed decreased strength and the weight loss could be 10% (Gupta and Sachdeva, 2019; Palankar et al., 2016). This is because the cementitious materials and the free-CaO residual tend …
This article reports on investigations of the resistivity and chloride migration coefficient (D RCM) obtained in the accelerated Rapid Chloride Migration test for slag cement-based concretes.Determinations of the resistivity and D RCM were performed on 47 different concrete compositions, up to the age of 182 days. The obtained results …
The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree Celsius. The process is carried out in a blast furnace.
Portland Slag Cement (PSC) is a versatile cement type that offers numerous advantages in construction projects. It provides strength, durability, workability, and cost-effectiveness. PSC finds applications in various sectors, including mass concrete, marine construction, and precast concrete products. While it has some disadvantages such as ...
Using steel slag in concrete ultimately reduces the amount of waste generated by the steel industry. Industrial waste is highly contaminating, so giving it a new value is a great way to contribute ...
Slags are used as a replacement of portland cement in amounts typically between 25 and 70% of the total mass of cementitious material. Slag concretes have improved long-term …

Slag. Ground-granulated blast-furnace slag (GGBFS) is produced by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder. When added to concrete, GGBFS enhances a range of performance characteristics such as the reduction of ...
Slag cement is used in durable concrete construction throughout the United States. This collection of videos and webinars are here to help answer any questions that may arise …

Reading time: 3 minutes. Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.

Producing and Placing Slag Cement Concrete. Slag cement must be stored in bins or silos to protect from contamination. Info Sheet #8. Mitigating the Risk of Alkali Silica Reaction. Alkali Silica Reaction (ASR) is a chemical reaction between the alkalies in Portland cement and materials present in aggregates.
Supplementary cementing materials (SCMs) contribute to the properties of hardened concrete through hydraulic or pozzolanic activity. Typical examples are fly ashes, slag cement (ground, granulated blast-furnace slag), and silica fume. These can be used individually with portland or blended cement or in different combinations. Supplementary ...
Slag cement is used in nearly all types of concrete construction: pavements, structures and foundations, mass concrete (i.e., dams and retaining walls) and precast concrete …
The properties of blast furnace slag cement are as follows, The density of slag cement is 3.04 g/cm³. While the setting time is 60 minutes initially, the final setting time of this cement is 600 minutes. The …
The carbonation coefficients increase as the replacement of cement by slag in the concrete increases. The carbonation resistance of BFS concrete is poor and although curing for longer times (up to 3 months) increases the resistance, the performance remains low, especially for cement replacement levels of 70% and above.
The Slag Cement Association is an organization of companies that produce and ship slag cement in the United States; these shipments represent over 95% of all slag cement …
Slag, produced during the iron-manufacturing process, is born when raw materials undergo melting within the intense heat of a blast furnace, reaching a molten state. Slag undergoes a structural transformation as it cools rapidly through granulation, gaining cementitious properties. Ground to a finer consistency than GU Portland cement, it ...

Whether it's creating the cement powder, mixing the concrete with water, or curing the concrete, the results vary. Blue/Green Discoloration . Blue and Green Discoloration are often found when slag cement is used with a mixture of Portland Cement. Slag cement is a hydraulic cement and is known for its whiteness.
The Slag Cement Association (SCA) has been honoring the exceptional use of slag cement in concrete construction since 2010 with the Slag Cement in Sustainable Concrete Awards Program. These case studies show exemplary use of slag cement in the following categories: Architectural, Durability, Infrastructure, High Performance, …
chemical admixtures used in concrete, and the effects of chemical admixtures in concrete containing slag cement are similar to the effects in ordinary portland cement concrete. Slag cement does not contain carbon and will not cause fluctuations in air content. In addition, slag cement is compatible with pozzolans such as fly ash or silica fume.
Sustainability. Slag cement is a recovered material from the iron production process and because of this, reduces the environmental impact of concrete mixtures. Additionally, slag cement is very effective in reducing permeability and increasing durability in concrete.
