Procem is a packed Portland cement that is suitable for use in civil engineering applications such as structural concrete, piling and screeds.

To achieve optimum performance from Procem in concrete, mortar, render, screed or grout, it is essential that it is correctly specified and used. Attention should be given to an adequate cement content, a water/cement ratio as low as possible consistent with satisfactory placing and thorough compaction and to adequate curing. Reference should be made to the following documents:

BS 8500: Concrete - Complementary British Standard to BS EN 206-1.
BS 5628: Part 3: Code of Practice for the use of Masonry.
BS EN 13914-1: Design, preparation and application of external rendering and internal plastering.

Sulfacrete should be used where increased resistance to sulfates is required.

• Grey colour.
• Consistent strength meeting all the conformity criteria in BS EN 197-1.
• Compatible with admixtures such as air-entraining agents and workability aids, with cement replacement materials such as fly-ash and ground granulated blastfurnace slag and with pigments. Trial mixes are recommended to determine the optimum mix proportions.
