Available brands are Dalmia, Ramco, UltraTech, Coromandel, Penna, Zuari, Maha, Priya and many more. Visit to check the prices of OPC and PPC across the brands and buy the required quantity for your project. Both OPC and PPC are used in the construction of slabs as well.īuy OPC and PPC for low prices at. People often wonder, which is better – OPC or PPC? To sum it up, OPC is commonly used for commercial purposes, and PPC is used for residential purposes. Which cement is better for your construction project? (v) Best choice for mass concreting, plastering and masonry. (iv) PPC has lower initial strength compared to OPC, but hardens over a period of time with proper curing. (ii) PPC is highly resistant to sulphate attacks and hence used in construction of dams, foundations and buildings nearby the sea shore, reservoirs and marine constructions. (i) PPC uses natural and industrial waste, hence reduces environmental pollution. Advantages of PPC (Portland Pozzolana Cement) (iii) Shorter curing period, and as a result low curing costs.
(ii) Higher initial strength compared to PPC. (i) Due to its shorter setting time (compared to PPC), OPC is recommended in projects where props are to be removed early. (vi) OPC is usually costlier than PPC Also Read: Buying Guide for TMT Steel Bars Advantages of OPC (Ordinary Portland Cement) (v) OPC provides lower resistance to aggressive chemicals compared to PPC (iii) OPC cannot be used for mass concreting due to its high heat of hydration, whereas PPC can be used for mass concreting (ii) OPC has higher initial strength compared to PPC (i) OPC has shorter setting time compared to PPC OPC vs PPC – Differences between OPC and PPC Cement 6 Differences between OPC and PPC cement PPC is available in one grade and its strength is similar to that of OPC 33 Grade after curing. Pozzolana materials are added to the cement in the ratio of 15% to 35% by weight. Pozzolana materials such as fly ash, calcined clay, and volcanic ash are added to OPC, and the result leads to PPC. The Grade number is the respective compressive strength (in MPa) achieved after 28 days of curing. OPC, in turn, is classified into three grades: OPC 33 Grade, OPC 43 Grade, and OPC 53 Grade. Curing plays a crucial role in determining the structural integrity of the construction. Curing period is the time taken by concrete to get settled completely and maintain the moisture for hydration reaction to occur normally so that concrete develops hardened properties over time. In addition to the quick setting time, OPC also takes very little time for curing. OPC is produced by grinding limestone and secondary materials to fine powder.Ĭompared to PPC, OPC usually takes little time for setting, which is important for large scale constructions, thus speeding up the process of determining the length of the construction period. OPC has been the most common type of cement used for years due to its abundance and low production cost. This article helps you in finding out what are the differences between OPC and PPC, and which type of cement is better for your construction project. There has been a lot of debate around OPC vs PPC and which one of the both is more suitable for a specific construction. There are two main types of cement available, and choosing the right type of cement determines the quality of the construction. More complicated enhancements include displaying the names and data types of Objective-C methods even if symbols have been stripped, and adding comments that describe member variables, function calls, static data and more.Cement is the most important material used in constructions as it binds the rest of the building materials together and ensures strength and durability of the structure.

Simple enhancements include adding the machine code of each instruction and the offset of each instruction from the beginning of a function. otx uses otool(object tool) to disassemble a Mach-O executable file, then enhances the disassembled output.
