PRESENTED BY GUIDED BY. SAJMI MAMSHAD MAYA G NAIR. 1 INTRODUCTION Silica fume is also referred to as micro silica or condensed silica fume but the term silica fume has been generally accepted The addition of ultra fine particles in concrete improves strength of concrete The optimum proportion of silica fume is found in between 20% and 25% by weight of concrete Silica Fume when react with

By using 10,000-psi (69-MPa) silica-fume concrete, the precaster was able to reduce section size for some elements, making transportation and erection simpler (Halmos 1986; Luther and 1987). In another precast application, the Montreal Airport Parking Structure, silica-fume concrete was used for 3000 elements subjected to accelerated curing.

Silica Fume. Silica fume or micro silica is an amorphous polymorph of silicon dioxide and silica. Silica fume is an ultrafine powder. It is a silicon and ferrosilicon alloy. Micro silica consists of spherical particles with an average particle diameter of 150 nm. It is a very reactive pozzolana due to its chemical and physical properties.

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are

NCI Thesaurus (NCIt) Silica is another name for the chemical compound composed of silicon and oxygen with the chemical formula SiO2, or silicon dioxide. There are many forms of silica. All silica forms are identical in chemical composition, but have different atom arrangements. Silica compounds can be divided into two groups, crystalline (or c

Daman K. Panesar, in Developments in the Formulation and Reinforcement of Concrete (Second Edition), 3.1.3 Silica fume. Silica fume is a by-product from the production of elemental silicon or alloys containing silicon in electric arc furnaces. At a temperature of approximately 2000°C the reduction of high-purity quartz to silicon produces silicon dioxide vapor, which oxidizes and

in concrete technology. More sticky mix can be obtained by addition of Silica fume in concrete. Using Silica fume in concrete increases its compressive, tensile, flexural and impact strengths and decreases permeability and bleeding. In this paper, an attempt is made to describe the suitability of silica fume in concrete.

The primary component of silica fume is amorphous silicon dioxide SiO2 in a range of 85 % - 98 %. The main impurities include carbon, silicon carbide and oxides of alkaline (earth) metals. As silica fume is generated from raw materials which inevitably vary in composition depending on the source, the impurities will also individually vary up to
