Silica fume should not be confused with fly ash. specific gravity 2.74 and fineness modulus 7.20 were used. 2.1.4. Silica Fume (Grade 920 D) Silica fume used was confirming to ASTM- C(1240-2000) and was supplied by “ELKEM INDUSTRIES” was named Elkem – micro silica 920 D. The Silica fume is used as a partial replacement of cement. The specific gravity of silica fume is 2.20-2.30. The surface area of silica fume particles can range between 13,000 m 2 /kg and 30,000 m 2 /kg, measured by nitrogen absorption equipment.

Silica fume specific gravity

2017-08-25 · Specific gravity. Specific gravity is a relative number that tells how microsilica/silica fume compares to water, which has a specific gravity of 1.00. Microsilica/silica fume has a specific gravity of about 2.2, which is somewhat lighter than portland cement, which has a specific gravity of 3.15. specific gravity 2.74 and fineness modulus 7.20 were used.

Specific gravity is defined as the ratio of the weight of material. The specific gravity of silica fume is 2.20–2.30 (Khan & Siddique, 2011; Tafraoui et al. 2016; Thomas, 2013). The surface area of silica fume particles can range weight calibrated volumetric batching on site, with silica fume added in bags (25 The boiled absorption, volume of permeable voids and bulk specific gravity, 18 Apr 2012 Tests for specific gravity, and compressive, indirect tensile and flexural Light- Weight Concrete Incorporating Fly Ash and Silica Fume.

The stabilizer materials used in this study was Silica Fume. Silica Fume used in this study brought from Shisher Export House, Raipur,(C.G.). The composition of SF is presented in table-1.

SILICA FUME Silica fume, also referred to as microsilica or condensed silica fume, is a byproduct material that is used as a poz-zolan (Fig. 3-7). This byproduct is a result of the reduction of high-purity quartz with coal in an electric arc furnace in the manufacture of silicon or ferrosilicon alloy. Silica fume Packaging Details Packing for high quality specific gravity of silica fume in concrete pdf : 1.25Kg/plastic woven bag 2.1000Kg/ jumbo plastic wover bag 3 Also can be packed according to your requirement. Port QingDao/TianJin port Lead Time : About 10 days after receiving the deposit 2018-12-18 The specific gravity of silica fume is in the range of 2.2 to 2.3.
