Description

Formerly known as Ordinary Portland Cement (OPC), is manufactured to conform to British Standard BS EN 197-1. OPC Ordinary Portland Cement (OPC) is the cement that has been commonly used throughout the world in civil constructions. engineering and building-works.

It is versatile, durable and helpful for strong construction purpose. However, it is the least sustainable type and used for general construction (which requires higher early strength) like bridges, pavements, structural non pre-stress, precast units, high strength reinforced foundations.

Portland Cement (PC) is the name given to a cement obtained by intimately mixing together calcareous & argillaceous, or other silica, alumina and oxides of iron-bearing materials, burning them a clinkering temperature up to about 1450°C, and grinding the resulting clinker to required fineness.

Other features of this cement are:

• Components of Portland Cement (PC) are Portland Clinker : 95-100% Gypsum : 0-5%
• It conforms to the Bangladesh Standard BDS EN 197-1:2003 CEM-I 42.5 N and 52.5 N, European Standard EN 197 type CEM I, and American Standard ASTM C 150 Type-I mark.
