Ordinary Portland Cement (OPC) is the most commonly used cement in construction as it offers a low-cost proposition with high resistance to cracks and shrinkage. Produced by grinding a mixture comprising limestone and other types of raw materials, this cement genre comes in three types of grades: OPC 33 grade, OPC 43 grade, and OPC 53 grade.

Portland Cement Compressive Strength. The most common strength test, compressive strength, is carried out on a 50 mm (2-inch) cement mortar test specimen. The test specimen is subjected to a compressive load (usually from a hydraulic machine) until failure. This loading sequence must take no less than 20 seconds and no more than 80 seconds.

Ordinary Portland cement (simply called ordinary cement) refers to the hydraulic binding material ground by mixing Portland cement clinker, 6% ~ 15% blended materials, and appropriate amount of gypsum, code-named P• O. The maximum amount of active blended materials mixed in cement should not exceed 15% of the total mass.

Advantages of Ordinary Portland Cement It has great resistance to cracking and shrinkage but has less resistance to chemical attacks. Initial setting time of OPC is faster than PPC so it is recommended in projects where props are to be removed early. Curing period of OPC is less than PPC and curing cost reduces.
