SILICA FUME

Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. Concrete containing silica fume has very high strength and can be very durable. Silica fume is available to be added to the mixture during concrete production. Benefits of adding silica fume include high early compressive strength, enhanced durability, increased toughness, higher bond strength, increased abrasion resistance on decks, floors, overlays and marine structures, and superior resistance to chemical attack from chlorides, acids, nitrates and sulfates and life-cycle cost efficiencies.

SLAG CEMENT

Using slag cement makes concrete more consistent, resistant to aggressive chemicals and less permeable. Slag cement has been used in concrete projects in the United States for over a century. Over the years, modern designers have been able to improve durability to produce the lowest life-cycle and maintenance costs possible. These long-term performance enhancements have allowed for a reduced environmental footprint of concrete while ensuring improved performance and increased durability.

PORTLAND CEMENT

The key to concrete is portland cement- the fine gray powder that binds sand and gravel into concrete’s rock-like mass. Portland cement produces highly durable and sound concrete due to a very low percentage of alkalis, chlorides and magnesia in its composition. It is commonly used for high rise buildings, commercial & industrial complexes, roads, runways, bridges and heavy defense structures.

FLY ASH - C

Class C: Fly ash produced from the burning of younger lignite or subbituminous coal has self-cementing and pozzolanic properties. In the presence of water, Class C fly ash will harden and gain strength over time. Unlike Class F, self-cementing Class C fly ash does not require an activator.

FLY ASH - F

Class F: The burning of harder, older anthracite and bituminous coal typically produces Class F fly ash. This fly ash is pozzolanic in nature. The glassy silica and alumina of Class F fly ash requires a cementing agent, such as Portland cement, quicklime, or hydrated lime, with the presence of water in order to react and produce cementitious compounds.
