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 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.
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.
For substructure guniting work, Ordinary Portland Cement (OPC) is typically preferred due to its strength and durability in underground conditions. OPC provides good bonding and sets quickly, making it suitable for applications requiring immediate structural integrity. Sulphate Resisting Cement (SRC) may be used in environments with high sulphate exposure, but for general substructure guniting, OPC is usually sufficient. Always consider site-specific conditions when making the final choice.

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..
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.

The specific gravity of Ordinary Portland Cement (OPC) 43 grade can vary slightly depending on the manufacturer and specific composition. However, as a general guideline, the specific gravity of OPC-43 grade cement typically ranges from 3.10 to 3.15. Specific gravity is a measure of the density of a substance compared to the density of water. It indicates how heavy a material is relative to an equal volume of water. OPC-43 grade cement generally has a higher specific gravity compared to water, which has a specific gravity of 1.0. It's important to note that specific gravity values can differ slightly based on factors such as cement composition, fineness, and variations in manufacturing processes. For precise information regarding the specific gravity of a particular brand or batch of OPC-43 grade cement, it is recommended to refer to the manufacturer's specifications or contact the manufacturer directly.
