Impact of Silica Fume on High-Strength Concrete
Abstract: For many decades, concrete has been the primary material used in construction because of itsreliability under normal conditions. However, certain applications necessitate concrete withexceptionally high compressive strength and durability, particularly in aggressive environments.Consequently, achieving compressive strengths in the range of 60–140 MPa is critical for thesedemanding situations. Silica fume, a by-product of silicon and ferrosilicon smelting processes, hasgained recognition as an effective cementitious material for enhancing concrete properties. Thisdissertation investigates …
