What is Portland Pozzolana Cement :

• Portland Pozzolana Cement (PPC) is produced by inter-grinding high quality clinker with a balanced chemical composition, fly ash containing high reactive silica, and high purity gypsum without deleterious materials. It is also manufactured by blending of high quality Ordinary Portland Cement with finer fly ash containing high reactive silica. These materials are judiciously proportioned in such a way that the cement has enhanced quality parameters.
• UltraTech Portland Pozzolana Cement provides better workability, colasive mixes, less bleeding, reduced cracks, reduced permeability, higher resistance to chemical attacks, and protection against corrosion of steel, and gives a superior finish. It also provides high ultimate strength. This cement is also suitable for general construction work in all applications (RCC, PCC, masonry and plastering).

Advantages of PPC Cement :

• UltraTech’s Portland Pozzolana Cement is renowned for its workability. The spherical cement particles have a higher fineness value and move more freely, allowing better filling of pores. It also reduces the rate of slump loss of concrete, particularly in hot weather conditions. PPC cement also reduces bleeding with its low water content, thus blocking bleed water channels.
• PPC being finer in nature, increases its paste volume, leading to an improved bond of concrete to steel. The cement also liberates lime during initial hydration thus reducing void spaces and subsequently reducing the permeability of concrete, offering the advantage of durability. It also prevents the growth of micro-cracks in the structure, which increases the strength of the structure.

Conclusion :

• Because the pozzolanic material reacts with the calcium hydroxide liberated by the hydrating Portland cement to form cementitious compounds, PPC increases the impermeability and density of the concrete. It can be used with confidence in the construction of hydraulic structures, marine works, mass concreting, and so on. It protects concrete against alkali-aggregate reactions.
