Investigations on Micro Silica (Silica Fume) as Partial .

Fresh concrete containing silica fume is more cohesive and less prone to segregation than concrete without silica fume. Experience has shown that it is necessary to increase the initial slump of concrete with silica fume by approximately 50mm above thanrequired for conventional CEM I concrete to maintain the same apparent workability.

Effect of Silica Fume on Concrete Properties and Advantages

Silica fume will protect concrete against deicing salts, seawater, and road traffic and freeze/thaw cycles. Rebar corro sion activity and concrete deterioration are virtually eliminat ed, which minimizes maintenance expense. • Highstrength concrete enhanced with silica fume; provides architects and engineers with greater design flexibility.

Reactive Powder Concrete (RPC) PPT

07/03/2014 · Composition of Reactive Powder Concrete RPC is composed of very fine powders (cement, sand, quartz powder and silica fume), steel fibres (optional) and superplasticizer. The superplasticizer, used at its optimal dosage, decreases the water to cement ratio (w/c) while improving the workability of the concrete.

Make your High Strength Concrete with Silica Fume new

 · Its new age, we are now demanding high strength and durable concrete, we have metro trains, high dams, Bridges with heavy loads and many structures that required to be of high Strength. So in demand, we need a material which much satisfy the Demand of increased properties. Therefore, Silica Fume come in action.
