Being the general-purpose cement used for preparatory construction work, Ordinary Portland Cement is considered the most Commonly use cement type worldwide. Best suitable for the utilisation of pre-cast industries where rapid hardening is required, Ordinary Portland Cement is giving faster early strength, which is ideal for pre-cast/ fume hoods manufacturing. Also, it can be removed early from the product or the construction, as the expected high strength will be achieved early. The standards strength of cement mortar is obtained after 28 days, and the early strength can be determined in 2 days.
Mainly made with Portland Cement Clinker, Ordinary Portland Cement composition consist minor constituents not exceeding 5.0% of the total mass of cement to enhance the properties of the cement, such as workability.
As made for excellence, Ordinary Portland Cement meets the quality requirement specified by Sri Lanka Standard SLS 107:2015 with the strength Class of 42.5 N/R.
