One pound of silica fume produces about the same amount of heat as a pound of portland cement, and yields about three to five times as much compressive strength. Silica fume improves concrete in two ways the basic pozzolanic reaction, and a microfiller effect. Addition of silica fume improves bonding within the concrete and helps reduce permeability, it also combines with the calcium hydroxide produced in the hydration of portland cement to improve concrete durability. As a microfiller, the extreme fineness of the silica fume allows it to fill the microscopic voids between cement particles. This greatly reduces permeability and improves the paste-to-aggregate bond of the resulting concrete compared to conventional concrete. Dosage: 8% to 15% by weight of cement but as an addition not replacement. 8% to 10% High durability / Low permeability such as bridge decks or parking structures 10% to 15% High strength structural columns 10% max Flatwork The amount required is related to silica fume dosage and the water-cementitious materials ratio. Silica fume is cementitious, but typically is added to and not replacing the existing portland cement. Tip: The higher percentage of silica fume used, the higher the amount of super plasticizer needed – but mix can become “sticky”. Consider replacing about 1/3 of the super plasticizer with a mid-range water reducer to improve workability Purchasers are aware of basic concrete and cement mixing strategies and are aware of common safety practices when working with cement. Should you be interested we also have access to other admixtures and pozzolans such as Slag, & Fly Ash. Shipped Same Day! Normal 0 false false false EN-US X-NONE X-NONE
