The paper Newreach 95D is one of the newest building materials frequently used by building engineers and designers. It is a micro-silica powder concrete admixture that adds versatility and index parameters to Portland cement concrete, enabling it to be used in unprecedented ways. This new technology can significantly improve the strength, durability and impermeability of concrete. Newreach 95D has a wide range of applications, [...]

The Silica Fume Association is aware of instances in which silica-fume concrete prepared in a laboratory has failed to produce the expected hardened concrete properties, whether the property is compressive strength or low permeability. This problem is particularly common in laboratories having small, and often less efficient, concrete mixers. Silica fume is a very fine powder — the particles are approximately [...]

A few amazing silicon materials, what are their uses? This article focuses on several materials related to silicon materials, which are very similar in shape, color and application. They have the same points and different places compared to silica fume. So in some cases you need to know how to distinguish them, even though they are similar. [...]
This article examines how silica fume changes the properties of paste, mortar, and concrete. The effects of silica fume are attributed to physical and chemical mechanisms, both of which are described. Because the results of both the physical and chemical mechanisms are seen in modifications to the paste microstructure, Additionally, topics that are related to the mechanism of silica fume [...]
Silica fume has historically been available in three fundamental product forms: As-produced, slurried, and Densified. Densified silica fume is created by treating As-produced silica fume to grow the mass density up to a max of about 400 to 720 kg/m3. This increase in mass density is usually accomplished by tumbling the silica-fume particles in a silo, which induces surface charges [...]
Silica fume concrete is a mixture of three, components: aggregate, paste and silica fume. The paste is made of cement and water, in which silica fume is added, and finally mixed with aggregates of different sizes. In the form of silica fume concrete, concrete is a mixture of paste, silica fume and aggregate. The paste consists of Portland cement and [...]
