Materials, Molecular weight, Specific gravity, Concentration (%), Appearance, Water solubility  1 Mar 2016 The cement had a specific gravity of 3.12 and the fineness of 0.34 m2/g. A commonly commercial silica fume used in this study was supplied  Classification, specific gravity, compaction characteristics, swell and swell pressure, CBR and compressive strength tests had been conducted on the prepared  Specific gravity tests were performed on cement, fine aggregate, coarse aggregate and silica fume. 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.

Silica fume specific gravity

The specific gravity of silica fume is generally in the range of 2.2 to 2.3. Condensed silica fume is essentially silicon … Micro silica fume used in thermal … What is specific gravity – Answers.com. Specific gravity, usually referred to as relative density is the ratio of the mass of a given volume of a substance to the density of a different. Specific gravity Silica fume specific gravity is 2.2, which is somewhat lighter than Portland cement, which includes a particular gravity of 3.15.

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. The fine particle size of the as-produced silica fume makes it challenging to handle, from a particle perspective.
