·5.High alumina Cement:-This type of cement has rich alumina content about 35% which helps in gaining ultimate high strength within a short period.This type of cement is used where a structure is subjected to the action of sea water,chemical plants and furnaces.6.Blast furnace slag cement:-Cement Testing Types,Methods Equipment - Gilson Co.Separate air-entraining admixtures dosed directly into ready mix concrete batches have mostly replaced these modified cement types.2.ASTM C595/AASHTO M 240 is a prescriptive specification but covers blended hydraulic cements.It details the composition and tests required for blended hydraulic cements with Portland cement as the main Cement Types - Portland Cement AssociationThe heating that occurs in the kiln transforms the raw materials into new chemical compounds.Therefore,the chemical composition of the cement is defined by the mass percentages and composition of the raw sources of lime,iron,silica,and alumina as well as the temperature and duration of heating.
