Details
Bharati Cement – Portland Puzzolana Cement (PPC) is premium composite cement produced from superior quality Narzi limestone, using next generation German technology to meet international standards. The cement is manufactured by inter-grinding high quality clinker with carefully chosen, good quality High Reactive Silica (HRS). Which is collected from Electro Static precipitators (ESP) and contains high quality gypsum.
Hydration of blended cement
Ordinary Portland Cement + Water -> C-S-H Gel + Ca (OH)2 (Alkali)
High Reactive Silica (HRS) + Alkali -> Secondary Gel Formation
As a result of the above secondary hydration, pore refinement takes place, making the concrete more impermeable to sulphate and chloride attacks. This makes the concrete structure more durable.
Advantages
Low heat of hydration
Resistant to sulphate and chloride attacks
Resistance to alkali silica reaction
Reduction in water demand
Reduced bleeding due to high fineness of cement
Pore refinement leading to improved density of concrete
Applications
Mass concrete work
Marine works
Residential and commercial high rise buildings
Industrial structures
Suitable for wide range of applications as a substitute for OPC
