Silica fume is similar to fly ash, but has a particle size 100 times smaller. This results in a higher surfacetovolume ratio and a much faster pozzolanic reaction. Silica fume is used to increase strength and durability of concrete, but generally requires the use of superplasticizers for workability.

Novel Concrete can Withstand Road Salt Deterioration

May 19, 2017· Farnam developed a technique for using slag, fly ash and silica fume — remains from the smelting process and coal furnaces— in a new concrete blend that is more durable because it does not react with road salt. His research findings have been recently published the journal of Cement and Concrete Composites.

In this investigation the compressive strength and abrasion resistance of PC concrete, HVFA concrete and HVFA concrete blends with SF and slag were studied. The inclusion of FA was 70 % as cement replacement; then 10 and 20 % from FA was partially replaced with individual SF, individual slag and equally combinations of SF and slag.

Jun 13, 2010· The hydration (mixing with water) of Portland cement produces many compounds, including calcium silicate hydrates (CSH) and calcium hydroxide (CH). The CSH gel is known to be the source of strength in concrete. When silica fume is added to fresh concrete it chemically reacts with the CH to produces additional CSH.

Effects of Silica Fume on Concrete Compressive Strength

The effects of silica fume (SF) on compressive strength of concrete have been analyzed. The compressive strength results of concrete mixed over different water–binder ratios as well as different replacing percentages of SF were analyzed. The results of the experiments showed that when the polymer/binder materials ratio increases, the compressive strength of concrete decreases.

Since the concrete with 8% silica fume had a higher 28day compressive strength ( MPa) than the control concrete without silica fume ( MPa), the concrete with silica fume is likely to have a lower temperature rise as compared with the control concrete of equivalent 28day strength by reducing cementitious materials content with the same water content.
