Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.

Ordinary Cement is used for ordianry works like building walls, and other ordinary structures.Generally OPC or PPC are ordinary cements.Special cements are used for special works of greater importance.Special Cements are white cement, colored cement, hydrophobic cement,etc.,
43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.
Portland Pozzolana cement (PPC) is manufactured by a combination of pozzolanic materials. Pozzolana is an artificial or natural material that has silica in it in a reactive form. Along with pozzolanic materials in specific proportions, PPC also contains OPC clinker and gypsum. These pozzolanic materials include volcanic ash, calcined clay or silica fumes, and fly ash which makes around 15% to 35% of cement weight.

Well, both types of cements have got merits of its own. OPC is a pure type cement releasing heat energy at a faster rate & the chances of shrinkage cracks are higher. PPC is a low heat cement in comparison to OPC requiring lesser degree of immediate post concrete setting curing. OPC is not suitable for hot weather conditions. PPC is suitable for adverse weather conditions. OPC cannot be used for thick & massive elements. PPC is to some extent suitable for thicker elements. Temperature controls are better conducted on PPC.
OPC DA will access the real time value from control system. OPC HDA will access the real time value of historian processed. Hence the historian will save the value in their database as well as it feed to OPC server also.

Ordinary Portland Cement sets more quickly, and attains 85% of its maximum strength within 7 days. OPC is most valuable in large construction projects Portland Pozzolana Cement (OPC mixed with fly ash) takes longer to get to full strength, but it is more eco friendly, because it neutralizes otherwise toxic fly ash, and it is more resistant to corrosive environments. PPC can be used in most situations that OPC can.
Psc is always first choice because psc cement gives more strength than opc and also psc cement setting time is slower not that much it will give same strength in 28 days... Because of slower setting cracks will not appear or there is very less chance to appear cracks and it will requires lesser curing than opc..
