Newreach Microsilica,Silica Fume Grade 85-97 High Quality,on Sale.

Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product during silicon and ferrosilicon alloy production. According to the SiO2 content, our products can arrange form grade 85% to grade 98%. According to the bulk density, we can divide our products into densified silica fume and undensified silica fume. (1). Silica fume in Concrete . Can increasing strength, density . Frost resistance, Early strength. . abrasion resistance performance. . anti-cavitations (2). Silica fume in Cement Strengthen cement impermeability. Strengthens the fiber cement product (3). Silica fume is used in refractory Greatly improved products strength and high-temperature performance. (4). Silica fume In shotcrete applications, there is less material waste and greater efficiency of product use. · High electrical resistivity and impermeability · Significantly less rebound loss · Mitigates reinforcing steel corrosion · Improved bonding strength · Thicker applications with each nozzle pass (5) Other Applications for Silica Fume . Rubber industry . Anti-caking industry . Pellet binder . Waterglass industry   Chemical and physical properties Properties Unit Specification SiO2 % > 85.0 Cl % <0.3 Moisture % < 3.0 Bulk Density (U) kg/m3 200 – 350 Bulk Density (D) kg/m3 500 – 700 Loss on Ignition,LOI % <6.0 Specific surface(BET) m2/kg 15000 - 35000  Application  Suitable for all concrete and mortar applications where the benefits of silica fume are required: · Higher compressive strength · Increased durability – Longer service life for structures · Enhanced rheology – Control of mixture segregation & bleed  Newreach silica fume(Microsilica) into the concrete mixer and mix thoroughly with the other mixture ingredients, adopting a procedure that ensures full dispersion of the product.  Dosage varies depending on application.  Contact Newreach for information and advice.     Description Newreach silica fume is a dry silica fume available in two main forms.  Undensified and Densified.  In use, it acts physically as an interactive filler and chemically as a highly reactive pozzolan.  A key ingredient in many construction materials, Newreach Microsilica is used in cement products as a process aid, to improve ingredient dispersion and to improve hardened properties and overall durability.   Packing Available in a range of packaging options, including: · 25 kg paper bags & 1000 kg jumbo bags. · Big bags in various designs & sizes · Bulk road tanker Please contact our representative for more details   Storage & handling  Newreach silica fume should be stored in dry conditions and not exposed to moisture.
