Product Information

 

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 PROPERTIES

  • Amorphous silica
  • Silicon dioxide > 85%
  • High pozzolanic activity

 

 

 

 

 

 

 

 

 

 

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

 

PHYSICAL PROPERTIES

  • Particle size: < 0.2µm (approximately 100 times smaller than the average cement particle)
  • Specific surface: 15 to 27 m ² /g
  • Bulk density:

(as-produced): 150 to 450 kg/m ³

(densified): 480 to 750 kg/m ³

 

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
