History Portland Cement British Cement Roman Cement Hydraulic Limestone

TYPES OF CEMENT

Mostly used in general construction (most buildings, pavements, precast units, etc) GENERAL PURPOSE

This type of cement is used in structures exposed to soil or water containing sulfate ions SULFATE RESISTING CEMENT

This type of cement is used rapid construction, cold weather concreting. HIGH EARLY STRENGTH

It is most suitable for massive structures such as dams. LOW HEAT PORTLAND CEMENT

Widely used for decoration. WHITE PORTLAND CEMENT
