Also known as Ordinary Portland Cement (OPC), our CEMI is a high-performance, pure cement product manufactured at our Hope and Kinnegad plants. It can be used in a variety of construction applications and provides excellent early and long-term strength development making it ideal for structural concrete, precast elements, and civil engineering projects where strength and durability are critical. Applications: ready-mix concrete, mortar and soil stabilisation. Properties: Grey colour Consistent strength meeting all the conformity criteria for BS EN 197-1 7- and 28-day strength Compatible with admixtures such as air-entraining agents and workability aids, with additions such as fly-ash and ground granulated blast furnace slag and with pigments. Trial mixes are recommended to determine the optimum mix proportions Concrete, mortars and grouts containing Portland Cement must be specified and used correctly for best performance. The cement content must be correct and the water:cement ratio as low as possible consistent with satisfactory placing, thorough compaction and effective curing.
