Re-Act4 & Sustainability
Tech Silica Re-Act 4™ provides a premium factor in both function and application of sustainability. This is how Re-Act 4™ can make a difference in the longevity and viability of your products. Review the information below to see how Re-Act 4™ can provide confidence that you are making the sustainable choice for your next project.
Applicability for Sustainability:
- Replacement for SCMs becoming scarcer and in-demand such as Fly Ash, Slag, and Silica Fume
- Replacement for traditional Portland cement that is heavy in CO2 emissions
- Increases strength of concrete
- Increased durability
- Less linear shrinkage
- Reduction of efflorescence
- Compressive Strength
- Chloride ion resistivity
Implementation:
- In projects that need a green SCM replacement that meets the ASTM requirements of other SCMs such as fly ash and slag
- High resistance to sulfate and natural corrosions promotes the implementation of concrete projects that will be subjected to harsh conditions and chemical attack
- High compressive strength that promotes durability saving life cycle costs for projects in high-impact areas
- High resistivity to chloride ion erosion which makes it a perfect SCM for implementation in marine concrete that includes bridges and tunnels that are submerged in water
- High resistance to the freeze that cycle allows concrete to last longer in cold weather
Why:
- Substitutions for SCMs like fly ash where their production sites which are coal plants are closing rapidly reducing the supply, while simultaneously cutting back on coal production which is a high greenhouse gas emission contributor
- A 100% recycled product that cuts back on processing that contributes to greenhouse gas emission
- Creates an avenue for material waste to be repurposed for environmental use
- Cuts back on landfill waste
- Readily available in the millions of tons reducing SCM shortages in the infrastructure supply chain
- Reduces the production cost of traditional concrete
Sustainability Fact: The United States supplementary cementitious materials market size is estimated to reach 6.8 billion by 2030, which means high demand and limited sources is going to promote new SCM replacements [1]
