R-E-D Silica Fume
For Refractory Castables
R-E-D Silica fume used in refractory castables provides better particle packing. Silica fume used requires less water, while maintaining the same flow characteristics. Silica fume used also promotes low-temperature sintering and the formation of mullite in the matrix of castables. This allows production of castables which have a low permeability to gas, slag and metal penetration. Castables made with silica fume are stronger than non-silica fume castables, especially at high temperatures and higher density. Silica fume use will attain lower porosity and are more volume stable.
​
R-E-D Silica fume has a stable pH and a low impurity level and is perfectly adapted to the requirements of refractory castables. Its use improves the flow, mechanical properties (especially hot strength), and durability (via permeability reduction).
Silica Fume & Sustainability
R-E-D Industrial Products Silica Fume provides a premium in function and application sustainability. This is how our silica fume product line can make a difference in longevity and viability. See the information below to find out how silica fume can provide confidence that you are making the sustainable choice for your next project.
​
Applicability for Sustainability:
-
Increased strength in concrete structures
-
Longer durability
-
Resistance to alkali-silica reaction (ASR)
-
Low permeability to intrusion from corrosives such as water, salt, chloride, and other natural elements
-
Reduction of life cycle costs
-
Abrasion and impact resistance
Implementations:
-
Low permeability makes it well suited for structures that are immersed or near oceans, rivers, and water sources such as bridges, dams, and tunnels.
-
The ability to protect from abrasion and impact resistance provides a boost in protection for rebar from deterioration and replacement.
-
Increased strength for use in more wear-and-tear concrete structures that need to reach the standard life cycle span of 50 years.
​
Why:
-
Increase sustainability in concrete projects
-
Lower life cycle costs of infrastructure and building projects
-
An ethically sourced product that can boost your green initiatives
Sustainability Fact: 39% of infrastructure in America is older than its designed lifetimes, while nearly 10% are structurally deficient and 14% are characterized as functionally obsolete [1].
Creating structures with sustainable solutions such as silica fume are paramount to promoting your project's vitality into the future.
