Microfine portland cement is a type of cement that has very fine particles and a high specific surface area. It is used for grouting applications in rock and soil injection, where it can penetrate into tight joints, fissures and pore spaces, and provide a watertight and durable seal. Microfine portland cement can also improve the strength and stability of the grouted mass, and resist chemical attacks and corrosion.
There are different grades of microfine portland cement available in the market, depending on the fineness and the setting time. One of the common ways to measure the fineness of cement is by using the mesh size, which indicates the number of openings per inch of a sieve. The higher the mesh size, the finer the cement particles.
