Chapter 2 Silica Fume

Fume2.1 IntroductionSilica fume (SF) is a byproduct of the smelting process in the silicon and f. rro-silicon industry. The reduction of high-purity quartz to silicon at temperatures up to 2,000 C produces SiO2 vapours, which oxidizes and condense in the low-temperature zone to tiny particles consisting of n.

Durability performance of structural concrete containing silica fume

The hardened properties of concrete mixes containing silica fume and pre-coated crumb rubber were investigated by Onuaguluchi and Panesar (2014). They concluded that the synergistic effect of coated crumb rubber and SF as cement replacement material significantly enhanced the mechanical properties of the mixes.
