Portland Cement Type GUL

Portland Cement Type GUL (i.pro Contempra) is a specially formulated portland-lime cement. While regular portland cement may contain up to 5 percent limestone, i.pro Contempra is manufactured by intergrinding regular clinker (the main ingredient in cement) with up to 15 percent limestone. By reducing the amount of clinker used in manufacturing cement, this process naturally reduces the amount of energy and greenhouse gas emissions required to manufacture it. i.pro Contempra is a direct result of Essroc’s commitment to proactively improve its environmental footprint with state-of-the-art, sustainable products to met today’s building needs.

Portland is classified in five major categories called types. The type of cement used in a project will depend on the application and the concrete’s performance requirements.

Concrete Mix Proportions
  Parts by Volume      
  Portland Cement Clean sand Gravel or Stone Total Concrete
3,000-4,000 psi 1 2 3 4.33
2,500-3,000 psi 1 3 4 5.37




After concrete is placed, (between 50ºF and 75ºF) adequate curing is vital. Freshly mixed concrete contains more water than required for complete hydration of the cement. Good curing of the cement means that evaporation should be prevented or reduced. Sprinkle surface with water fog or cover surface with moisture-retaining fabrics such as burlap or cotton mats or even plastic spraying compound. The longer the concrete is kept moist, the stronger and more durable it will become.


Avoid direct contact with dry or wet Portland. Can cause irritation and severe burns to eyes and skin. Repeated inhalation can cause lung disease. Wear tight-fitting goggles, dust masks, protective clothing to prevent skin contact. Wash thoroughly after handling. In case of eye contact, flush with water and seek immediate medical attention.
