SikaFume is a concrete additive in powder form, based on silica fume technology. SikaFume contains extremely fine latently reactive silicic dioxide. The presence of this
SikaFume-50 S (GB) is a concrete additive based on silica fume technology. It is a mineral admixture composed of very fine solid glassy spheres of silicon dioxide. It is a
With the use of SikaFume the concrete will show the following properties: High stability of green concrete. Highly increased durability. Excellent frost and de-icing salt resistance if
Supplementary cementing materials Daman K. Panesar, in Developments in the Formulation and Reinforcement of Concrete (Second Edition), .1.3 Silica fume Silica fume is
17. Juni 2023 This study is about silica fume (SF) which is used in geopolymer concrete, silica fume an extremely pozzolanic substance, a ferrosilicon industry by-product is
1. Jan. 1996 Silica fume (SF) is an industrial byproduct mainly from ferrosilicon producing companies. Condensed silica fume is a very fine, amorphous, and reactive mineral
SikaFume is a concrete additive in powder form, based on silica fume technology. SikaFume contains extremely fine latently reactive silicic dioxide. The presence of this substance imparts greatly improved internal cohesion and water retention in the fresh concrete. The concrete becomes extremely pliable and pumpability is substantially
While the first trials of silica fume as an additive in concrete were in the 1950s, at that time much of the silica fume was simply discharged into the atmosphere. It was only with increased environmental legislation in the late 1960s that silica fume began to be collected in bag filters, whereupon manufacturers began to search for a use for the material. With
Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximay 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600 kg/m 3.The specific
10. Dez. 2022 HSA Microsilica is well-known for providing high-quality silica fume to concrete manufacturers, which is one of its most important business practices. Food-grade fumed silica is an important inorganic material in the food industry, according to the Food and Agriculture Organization. Because it is a polymeric material, it can absorb liquids and
13. Okt. 2023 This paper deals with the optimization of reactive powder concrete mixtures with respect to the addition of silica fume and the type of polycarboxylate superplasticizer used. First, the properties of reactive powder concrete with eight different commercial polycarboxylate superplasticizers were tested in terms of workability, specific weight, and
28. Sept. 2022 In this study, the effect of silica fume on the mechanical properties of concrete is carried out at a constant water–cement ratio of 0.49 with different percentages of silica fume replacement experimentally with an objective to determine the optimum amount of replacement of cement with silica fume without compromising the requisite

Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO 2, commonly found in nature as quartz. In many parts of the world, silica is the major constituent of sand.Silica is abundant as it comprises several minerals and synthetic products. All forms are white or colorless, although impure samples can be
9. Dez. 2017 Due to the nature of its manufacture (a recovered by-product) and use in the concrete industry, silica fume is a material that can significantly contribute towards sustainable concrete construction due to the improvements in the performance of concrete. Because of its properties, silica fume can be used to significantly increase strength,
