Product Description
Concrete manufactured with supplementary cementitious material.
Metakaolin is used to produce high performance, high strength concrete. It is recommended for projects such as water pipelines, bridges & dams, paving and precast applications. Use of Metakaolin contributes to:
- Increased durability
- Increased compressive & flexural strengths
- Reduced permeability & efflorescence
- Increased resistance to chemical attack & prevention of ASR
- Reduced shrinkage
- Improved finishing
- Improved color & appearance
Fly ash
Is a by product of coal combustion, most commonly produced by coal fired electrical generating facilities. Fly ash is a cementitious material, meaning it has certain properties that cause it to harden upon exposure to water. In the presence of Portland Cement, fly ash can develop strength characteristics very similar to cement. Fly ash is also particularly beneficial for use in hot weather as it tends to slow the generation of heat in the concrete.
Slag cement
A by-product of iron manufacturing, can be added to ready mixed concrete to improve durability and reduce maintenance costs. The benefits of using slag include: better workability, easier finishing, greater strength, greater resistance to chemicals and lower permeability.
Uses/Applications
Can be used for most applications when ordinary Portland cement concrete is used.
Complementary/Accessory Products
Concrete tools and trowels, safety equipment (hard hats, eyewear, hearing protection and gloves)
Product Benefits
Energy efficiency through reduction of cement demand; may contribute to LEED point(s) for recycled content.

Whitetopping / Ultra-Thin Whitetopping
Inevitable when it comes time to repair an asphalt pavement, the typical solution is to mill and resurface. This endless cycle of repair is not only expensive and unsustainable but also creates traffic headaches for travelers.
Product Description
Inevitable when it comes time to repair an asphalt pavement, the typical solution is to mill and resurface. This endless cycle of repair is not only expensive and unsustainable but also creates traffic headaches for travelers.
Whitetopping provides a unique solution to this repair cycle by using the asphalt pavement's structural capacity to overlay a thin sheet of concrete onto the existing pavement. Effectively breaking the asphalt repair cycle, a concrete surface can be designed to last up to 40 years with minimal maintenance.
Structurally, a pavement system should be analyzed by first considering the strength of the existing pavement layers. Each underlying layer strengthens the base and allows the concrete surface to be thinner. In a conventional whitetopping design, no bond is assumed to exist between the concrete and asphalt surface.
The flexibility of whitetopping design allows it to be used for a variety of applications including: highways, airports, intersections, and city streets. Construction schedules are shorter since earthwork does not have to be redone, translating to fewer user delay costs for the traveling public. Entire intersections have been whitetopped in as little as 4.5 days.
While everyone knows concrete is usually more expensive in initial cost, it is also commonly known that pavements aren't built to stay open for only one year; they are expected to be permanent infrastructure. This means it is prudent to consider life cycle cost when comparing pavement alternatives. When considering construction cost savings and low maintenance costs, whitetopping easily wins the life cycle cost analysis.
Ultra-Thin Whitetopping
The aged asphalt taxiway/apron at the New Smyrna Beach Airport in Florida exhibited severe alligator cracking. The airport officials and DOT chose to overlay the area with a concrete ultra-thin whitetopping. Nearly 200,000 sy of pavement was overlaid with 2" to 3.5" of concrete. In the design of the ultra-thin whitetopping, the engineer assumes the concrete will bond the asphalt surface. This design assumption is different from conventional whitetopping that does not bond.
