Application Description Portland Cement Concrete User

Portland cement is manufactured by crushing, milling, and blending selected raw materials containing appropriate proportions of lime, iron, silica, and alumina. Most Portland cement particles are less than 0.045 mm (No. 325 sieve) in diameter. Portland cement combined with water forms the cement paste component of the concrete mixture.
