Concrete is a widely used construction material, and its properties play a crucial role in determining the strength, durabilitate, and overall quality of the final product. One such property is the specific gravity of concrete, which is a measure of its density compared to water. In this article, we’ll take a closer look at what […]

Silica fume Properties Silica fume, cunoscut și sub numele de Microsilica (CAS number 69012-64-2, EINECS number 273-761-1). It is divided into two types: densified microsilica and undensified microsilica . Microsilica is a fine powder with particle size less than 1 micron and has a high silicon dioxide (SiO2) continut de aproximativ 85% – 99%. Aplicații de fum de silice […]
