Silica fume (also known as microsilica) is very fine noncrystalline silica by-product resulting from the reduction of high-purity quartz and carbon in electric arc furnaces during the production of elemental silicon or alloys containing silicon.
Rubberized concrete is a type of concrete that utilizes crumb rubber particles as aggregate. Apart from reducing rubber pollution, studies have shown that an appropriate amount of rubber mixing into concrete enhances the elasticity, toughne...
Silica fume is an industrial by-product with fine particle size (avg. 0.1-0.15 μm), good fluidity, and is used in construction, refractory, metallurgy, chemical, etc. In recent years, fluidized bed technology has been used to reduce the ca...
Wet shotcrete is a mixture of cement, aggregate, accelerator, silica fume, and water, projected by pneumatic or other power at high velocity on a surface. The technology of wet shotcrete has advantages such as high construction mechanizatio...
Densified silica fume is mostly used for concrete applications. In order to evenly disperse silica fume after mixing it into the concrete, a de-densification process is required, which mixes water and silica fume at a 1:1 ratio (by mass) an...
Porous ceramics have been widely used in many fields due to their excellent performance, such as bioceramics, catalyst supports, high temperature gas filters, sensors and membrane reactors. Compare with ordinary mullite which already has a ...
Silica fume is commonly used as a concrete admixture and an additive for refractory materials, with an industry requirement that the content of SiO2 should be above 85%. The SiO2 content of silica fume collected from silica metal (98%) is r...
Expanded polystyrene (EPS) concrete is a kind of lightweight concrete made of organic and inorganic materials. Compared with ordinary concrete, it uses EPS particles in coarse aggregates, so it has lower density, better corrosion resistance...
PVA fiber reinforced engineered cementitious composite (ECC) is a new type of cement-based material that has characteristics of enhanced crack resistance, toughness, and strength, and is unlike ordinary cement materials which are brittle, a...
To produce magnesium phosphate cement (MPC), heavy magnesium oxide and ammonium dihydrogen phosphate are used as the main materials, along with boric acid, sodium tripolyphosphate, and additives like fly ash. The abovementioned components a...
Preparation Materials Cement: ASTM C150 Type I portland cement, 28-day compressive strength 72.5MPa; Silica fume: G92D silica fume (min. SiO2 content 92%); Fly ash: ASTM C618 Class F fly ash; Polypropylene (PP) fibers: length 15mm, diameter...
