low heat portland cement advantages

Extra Rapid Hardening Cement ... Low Heat Portland Cement. 1- Low heat of hydration is 20% lesser than that of OPC cement. Good speed of construction can be achieved as the strength is gained in relatively shorter time. Reference Indian Standard: IS:12600 But for large or bulk projects, it is more economical and durable than other Portland cement. The slag contains oxides of lime, alumina, and silica and easily replaces clay or shale used in the manufacture of ordinary Portland cement. Portland pozzolana cement (PPC) has following advantages when concrete is in its hardened state. Cement powder is usually stored in cement silos and then packed in bags by a cement packing machine. Uses of Low Heat Cement: 1. 4- Since it good sulphate resistant, It can be used in marine constructions/Coastal areas. equipment installation and equipment commissioning to equipment maintenance. Low Heat Cement Low Heat Cement is specially blended to provide a lower heat of hydration in concrete. Cement raw meals should be calcined in a cement kiln at 1350 ℃ to 1400 ℃ for 30 to 45 minutes and then cooled by a cement cooler to obtain cement clinker. Disadvantages As its name indicates, low heat cement releases low heat of hydration. Low heat cement is ideal for mass concrete engineering, heavy structure, and high strength concrete engineering, such as dam construction, marine engineering, wind turbine plinths construction, high-rise building foundation construction, underground or underwater works, etc. It is not suitable applied in low-temperature areas, and it is not used for small construction projects like residential construction because of its high price. The early strength of low heat cement is low, but the late strength growth rate is fast. The heat of hydration of Portland blast furnace cement is lower than that of ordinary Portland cement. Low Heat Portland Cement: This cement is so called because it develops low heat at the time of hydration. It is a Chinese  company that  specialized in manufacturing and exporting cement plants and cement equipment, providing the turnkey project from project design, equipment installation and equipment commissioning to equipment maintenance. 6- More high technical strength of concrete. Type IV is a low heat of hydration cement, used for massive concrete structures, such as gravity dams, where heat isn't released from the mass. LH,Email
