An Introduction To Admixtures Of Silica Added To Concrete
Microsilica which is better known as “Silica Fume” is basically found in powder (extremely fine) form, and gets produced as a residue from producing silicon and ferrosilicon alloy(s). Under a microscope, the particles can be identified as spheres, with the diameter of each particle being recorded at 150nm(on average). Mixed with concrete it provides better strength and stability.
What are the Silica Fumes?
Concrete is made into a reactive pozzolan when, mixed with this fine textured powder containing high levels of SiO2. Present day Contractors of concrete arguably always use Silica Fumes for Concrete (Concrete Admixture). The quality of the Concrete is improved giving it better strength and making it more durable. However, extreme precaution(s) should be taken while handling the Admixture.
