Silica fume has been widely utilized in the U.S. for the past quarter century in the ready mixed concrete industry. It is now universally known for its contributions to high performance concrete (HPC), primarily for applications of high strength-, high modulus of elasticity-concrete as well as providing low permeability concrete characteristics offsetting the accelerating properties of chloride-induced corrosion. This presentation will focus on the lesser known benefits of silica fume utilized at high addition rates from 15-25% (by the weight of cement) for applications in the heavy industrial sector. Abrasion, impact and chemical resistance are some of the durability issues addressed.Read More
