Microsilica (silica fume) is a by-product of silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. Physical characteristics: Color: gray or gray white powder Bulk density: 320-700 kg/m3 Chemical composition: Items SiO2 Al2O3 Fe2O3 MgO CaO Na2O Moisture Content 75-98% 1.0-0.2% 0.9-0.3% 0.7-0.1% 0.3-0.1% 1.3-0.2% Fineness: the fineness of the silica fume is less than 1 1/4m, and the average particle size is 0.1 0.3 1/4m, and the specific surface area is 20 - 28 m2/g. The fineness and specific surface area are about 80-100 times of cement and 50-70 times of fly ash. Maxtech Micro Silica supplies will be as per QCS 2014 (ASTM C1240): SiO2: >/= 92% LOI:

Micro Silica Powder that we offer is well processed and therefore, is the perfect option on which buyers can easily rely. We are named among the renowned Manufacturers, Exporters and Suppliers of Micro Silica Powder. It is formulated under the strict vigilance of experts so as to ensure its accurate composition. One can place retail as well as bulk orders for Micro Silica Powder with us. Description : Silica fume consists of very fine particles. Because of its extreme fineness and high silica content, silica fume is a highly effective pozzolanic material. Being a highly reactive pozzolan, silica fume chemically reacts with the calcium hydroxide present in the cement paste, creating a stronger calcium silica hydrate 'making it sticky'. The result is improved paste to aggregate bond (excellent for shotcrete) and higher concrete strengths. Silica Fume is typically grey in colour and is categorised as a supplementary cementitious material (SCM). Silica Fume is compliant to AS/NZ 3582.3:2002 and is described as a Densified Amorphous Fumed Silica. Typical Uses : Silica Fume can be used to produce all grades of concretes. The chemical and physical properties of Silica Fume can greatly enhance the strength performance and the bonding properties of concrete. Silica Fume can be used in various applications and projects: Commercial, Civil, Mining and Marine projects. Silica Fume is suitable for inclusion in general concrete mix designs and in particular has application in high strength/ performance concretes and shotcrete / spray mixes. Features : The addition of Silica Fume can provide; Increase compressive strength Reduces chloride ion permeability Increase abrasion resistance Enhanced sulphate resistance Improved durability Enhanced resistance to chemical attack and deterioration Increase bond strength
