Effect of Dosing Sequence of Micro Silica

However, currently silica fume is dosed in dry form at most of the batching plants. In this paper, an effort has been made to study the effect of dosing sequence of silica fume in the concrete mix in dry form, on the slump and strength characteristics of concrete.

USING BAGGED SILICA FUME - Silica Fume Association

RECOMMENDATIONS FOR BATCHING BAGGED SILICA FUME REMEMBER MIXING! Regardless of how the silica fume is supplied, don’t forget that your concrete will require thorough mixing to disperse the silica fume.Typically, only about 50 lb (23 kg) of silica fume are being added to 4,000 lb (1,800 kg) of other ingredients.

silica fume is roughly three times lighter than cement, densified silica fume being 30-40 pounds per cubic foot verses the traditional 94 pounds per cubic foot for cement. The result is densified silica fume occupies three times the silo volume as would a given weight of cement. A good starting point is to assume a silo capable

Batching Plant: Types, Advantages Disadvantages

A concrete plant also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement. Batching of concrete could be achieved by either weight batching or volume batching.
