Overview
Chemically engineered, high performance mineral additive
I-Crete is a blend of naturally occurring minerals and high performance supplementary cementitious materials that are chemically modified. I-Crete is made primarily from waste byproducts generated by other industries, byproducts that would normally be placed into landfills. The consistent chemical composition and tightly controlled particle size distribution result in highly reactive and superior quality pozzolans for concrete applications.
I-Crete has been chemically engineered using the concepts of solution chemistry and SCM reactivity to increase concrete's mechanical properties and durability. Chemically I-Crete is a heterogeneous blend of oxides of calcium, silicon and aluminum with no deleterious impurities. Utilization of I-Crete in concrete not only increases the strength and durability but also provides environmental and economic benefits.
I-Crete Benefits
Reduced Permeability and Chloride on Penetration
The supplementary cementing reaction of I-Crete Pozzolans provides increased strength and densification of the cementitious matrix, which has the beneficial effect of significantly reducing the porosity and permeability of concrete. One consequence of this is that concretes incorporating I-Crete Pozzolans will have reduced chloride ion penetration making them less susceptible to chloride-induced corrosion of embedded reinforcing steel.
Comparison with Other Pozzolans
The following table compares the properties of I-Crete with other common pozzolans.
