Microsilica cas no 69012-64-2 manufacturer PCC Group
Microsilica consists of extremely fine dust particles, which can be assumed to be on average 100 times smaller than the average size of a cement grain. For technical reasons, silica dust is delivered in a concentrated form as micro granules which are agglomerates of individual particles. Microsilica is a very important addition to tight concrete.
The silica fume is also called microsilica or microsilica fume. When ferroalloy is smelting ferrosilicon and industrial silicon (metal silicon). A lot of volatile SiO2 and Si gases are produced in the submerged arc furnace. After the gas is discharged, it is rapidly oxidized, condensed and precipitated with air. It is a byproduct of large
Durability Properties of High Strength Self Compacting

Nine concrete mixes were prepared with Marble Powder and Quarry Dust as sand replacement materials (12.5%, 25%, 50% separately, and 25%, 50% combined). The effect of the replacements on workability, tensile, compressive and flexural strengths and cost were studied. Marble Powder negatively affected the workability while Quarry Dust improved it.
2.3. Preparation of Quarry Dust The collected quarry residue from quarry site was first broken into smaller pieces with the use of a hammer. The broken quarry resides were then fed into jaw crusher to obtain 2-3 inches pieces required for ball milling operation. The quarry residues were then ball milled to obtain fine powder which was later
