Concrete produced with our slag cement CEMSlag TM often yields higher 28day compressive and flexural strength than comparable products. Reduced heat hydration Concrete produced with CEMSlag TM has lower heat of hydration that reduces thermal cracking, especially important for projects that involve mass concrete structures like dams.
Slag cement is commonly found in readymixed 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 .
Slag cement, or ground granulated blastfurnace slag (GGBFS), has been used in concrete projects in the United States for over a century. Earlier usage of slag cement in Europe and elsewhere demonstrates that longterm performance is enhanced in many ways.
The incorporation of airquenching steel slag of mm (in which the content of Fe 1 O is over 30%) into concrete to fabricate mechanically sensitive concrete was investigated by Li et al. in 2005 [21]; subsequently, Jia performed a systematic study of this concrete (as shown in Figure ) [23,50].
Concrete In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense readymixed concrete. Blast furnace slag can also be used to make Ground Granulated Blastfurnace Slag (GGBS) which is used as a cement replacement in concrete.
Role of Slag Cement in Creating Sulfate Resistant Concrete, July 9. Argos USA Assistant Cement Technical Director Ryan Bentz will explore how slag cement can be used to combat sulfates deleterious effects in concrete and the testing methods used to prove the materials effectiveness.
Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume. Silica fume is a byproduct from the manufacture of silicon.
01/10/2020#0183;#32;The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: Blastfurnace slagThe nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast

Aesthetic finish; a much lighter coloured concrete finish can be achieved compared to Portland Cementbased concrete. GGBS also helps to improve the reflectivity of finished materials (improving safety in dark environments) and contribute towards the reduction of crystalline deposits on concrete surfaces.

This will have little impact on the cost of an industrial concrete but could add #163;2 #163;3/m 3 on a lower grade footing concrete. You will also need to consider how wet the concrete needs to be: the price will increase the wetter the concrete is as the supplier will need to
Typically the 7day strength of a ggbs concrete will be 5565% of the 28day strength compared to 7080% for a similar CEM I Portland cement concrete. The reduction in earlystrength will be more noticeable at high GGBS levels and low temperatures. Similarly low cement content concrete, kerb backing etc, the reduction will be magnified.
