Our customers' most commonly used types and varieties of cement include our gray Portland, our white Portland, our masonry or mortar, our pozzolana Portland, and our oil-well cement.
Our gray Portland cement is a high-quality, cost-effective building material that is comprised of at least 95% clinker and 0-5% of a minor component (usually calcium sulfate). Our gray Portland cement meets all applicable chemical and physical requirements and is used in virtually all forms of construction, from hospitals and homes to schools, tunnels, and airports.

We are one of the world's largest producers of white Portland cement. We manufacture this type of cement with limestone, kaolin, and gypsum. Customers use our white Portland cement in architectural works requiring great brightness and artistic finishes, to create mosaics and artificial granite, and for sculptural casts and other applications where white prevails.
|
Masonry or mortar is a Portland cement that we mix with finely ground inert matter (limestone). Our customers use this type of cement for multiple purposes, including concrete blocks, templates, road surfaces, finishes, plasters, and pasting over baked red brick.
|
Our pozzolana Portland is a variety of cement made by grinding clinker, gypsum, and natural pozzolana —a raw material of volcanic rocks and ash. Customers use our pozzolana Portland cement for all kinds of construction; however, its optimum use is for construction projects that are in constant contact with water or are built in humid or saltpeter ground.
|
Our oil-well cement is a specially designed variety of hydraulic cement produced with gray Portland clinker. It usually forges slowly and is manageable at high temperatures and pressures. Produced in classes from A to H and J, our oil-well cement is applicable for each depth, chemical aggression, or pressure.
