The specific gravity of silica fume is 2.2. Silica fume is added with OPC to enhance the strength of HSCC. 50% of fly ash and 50% of GGBS are used for making HSGC. OPC 53 grade cement was chosen for making HSCC. The specific gravity of cement is 3.15.

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.

For the same dosage, samples with MIRHA have lower dry density compared to samples with silica fume because the specific gravity of MIRHA is lower than silica fume. 1,223 specific gravity of silica sand products are offered for sale by suppliers on Alibaba.com A wide variety of specific gravity of silica sand options are available to you, such as manufacturing plant. There are 29 suppliers who sells specific gravity of silica sand on Alibaba.com, mainly located in Asia. 2019-01-01 · Silica fume was available in condensed form and powder form.

Silica fume specific gravity

The specific surface area of silica fume can be measured with the BET method or nitrogen adsorption method. It typically ranges from 15,000 to 30,000 m 2 /kg. Silica fume specific gravity is 2.2, which is somewhat lighter than portland cement, which includes a particular gravity of 3.15. Adding silica fume to concrete mix will not density the concrete. This expression means that silica fume isn’t a substance that is crystalline.

working with silica fume and silica-fume concrete. Different chapters of the Manual may be of interest to concrete specifiers, concrete producers, concrete contractors, or concrete inspectors. The Manual is organized as follows: Chapters 1 and 2 provide basic information explaining what silica fume is and how it is used in concrete.

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. Silica fume specific gravity is 2.2, which is somewhat lighter than Portland cement, which includes a particular gravity of 3.15. Adding silica fume to the concrete mixture will not density the concrete in terms of increasing the density of the concrete.
