Currently, the class g cement used for the oil and gas wells cementing operations is imported from other countries. therefore, suitability studies of our locally produced ordinary portland cement and blended cement were carried out to overcome this matter.
Unlike portland cements, csa cements can use ordinary citric acid, often at doses of 0.2 to 0.4. straight csa cements such as rapid set cement actually benefit from moderate retardation. the structural silicate crystal growth occurs more slowly, and like old-growth wood, results in better concrete with higher strengths.

Portland cement, binding material in the form of a finely ground powder, usually gray, that is manufactured by burning and grinding a mixture of limestone and clay or limestone and shale.the inventor joseph aspdin, of england, patented the basic process in 1824, naming it for the resemblance of the cement when set to portland stone, a limestone from the isle of portland.
Other articles where ordinary portland cement is discussed cement types of portland cement for testing and materials astm ordinary type i, modified type ii, high-early-strength type iii, low-heat type iv, and sulfate-resistant type v. in other countries type ii is omitted, and type iii is called rapid-hardening. type v is known in some european countries as ferrari cement.
