INTRODUCTION

Microsilica (silica fume) is very fine non-crystalline silica which is the by-product of producing elemental silicon or alloys containing silicon in electric furnaces. It is a highly reactive material that is used to enhance the properties of concrete.

Chemical contributions—Because of its very high amorphous silicon dioxide content, microsilica is a very reactive pozzolanic material in concrete.

Physical contributions—The micro-filler effect of microsilica would bring about significant improvements in the nature of the concrete.

FEATURES AND BENEFITS

• In fresh concrete—Increasing cohesion, reducing bleeding
• In shotcret—Allowing greater thickness of shotcrete layers, reducing rebound, increasing bond strength
• In hardened concrete—Enhancing compressive strength and flexural strength, reducing permeability, improving durability, resisting chloride attack, sulfate attack and other chemical attack
• Constructability—Allowing one-pass finishing to shorten working time, reducing heat of hydration

APPLICATIONS

Microsilica concrete is widely used for high strength structures like:

High-rise columns

Precast bridge beams

Parking structures

Bridge decks

Marine structures

Dams

Nuclear waste storage facilities

High-speed railways

Oil wells
