Microsilica in Concrete - Types, Properties, and Practical ...

Microsilica in concrete improves its strength and durability as it provides more uniform distribution and a greater volume of hydration products, and decreases the average size of pores in the cement paste. Microsilica, also known as silica fume or condensed silica fume, is a mineral admixture composed of very fine solid glassy spheres of silicon […]

How Microsilica Improves Concrete - Concrete Construction

Microsilica is a mineral admixture composed of very fine solid glassy spheres of silicon dioxide. Most microsilica particles are less than 1 micron (0.00004 inch) in diameter, generally 50 to 100 times finer than average cement or fly ash particles.

microsilica concrete and a low-slump dense concrete without microsilica, both compounded for bridge deck overlays. Early strength of the microsilica concrete is lower. But after two days, values are about equal. After 28 days, microsilica concrete is about 40 percent stronger and after 56 days, 50 percent stronger (from Reference 2).
