Higher grade like 53 is not recommended to be used for plastering as it is known to develop shrinkage cracks due to its high strength. The OPC setting time is less as compare to PPC. ● It reduces the resistance to corrosion of steel reinforcement due to alkalinity reduction. IS codes used for Portland Pozzolana cement (IS: 1489-91, Part 1) Portland slag cement is the most suitable cement for concrete paths, mass concrete uses, structures and bases, pre-cast concrete, concrete open to sea water and oceanic use. The silicate formation in concrete made of PPC continues even after the slowing down of hydration. So, PPC is called as environmental friendly. … 02. 08. 04. The treatment period of OPC is shorter than PPC hence the cost of treatment is reduced, therefore recommended where the cost-prohibitive treatment will occur. Underwater bridge piers and abutments are also constructed by means of this type of cement. The production cost of this cement is less than the Ordinary Portland Cement (OPC). For the construction of hydraulic structures. Disadvantages of Ordinary Portland Cement It cannot be used for mass concreting as it has high heat of hydration as compared to PPC. Highly resistant to sulphate and chloride attacks. Some disadvantages of PPC is, the initial strength slightly lesser than that of OPC and the reduction in alkalinity causes loss of resistance against corrosion in steel reinforcement. 06. Less rate of development of strength initially than ordinary Portland cement. Advantages It is economical as in PPC a part (25%) of costly clinker of OPC cement is replaced by cheaper pozzolanic material. 05. Portland Pozzolana Cement use cases; Pros and Cons, White Portland Cement use cases; Pros and Cons. Mass concrete structures because of less liberation of heat. Portland Pozzolana Cement (PPC) – Uses, Disadvantages & More … Portland Pozzolana Cement also commonly known as PPC cement. It is used in drainage and sewage and sewerage systems. 11. PPC is environment friendly as it utilises the by-products from the coal fired thermal stations. Used in the construction of massive structures like bridge piers, dams, and other thick foundations. Ordinary Portland cement (OPC) is by far the most important type of cement. Portland Pozzolana Cement is used in the construction of buildings near seashores, dams, marine structures, dams, and other constructions in damp places. The pozzolana present in the cement increases the fineness and decreases the water content in the cement. Double Flight Staircase!!! Pros Amp Cons Of Portland Pozzolana Cement Ppc Over. Portland Pozzolana Cement (PPC) Portland Pozzolana Cement also commonly known as PPC cement. Therefore it is green material, hence ecofreindly and helpful in achieving green rating. 09. PSC Portland Slag Cement, commonly known as PSC, is blended cement. Disadvantages ● Less rate of development of strength initially than ordinary Portland cement. PPC made structures are generally less porous because most of the lime is dissolved during early hydration. ● Setting time is longer than opc 53 cement. ( Bridge piers, dams ) For hydraulic structures; Sewers and Sewage This type of cement bleeds less. Hello, there are some qualities of these each cement. Hence it is more suitable for plaster, masonry and mortar work. Barrages, which remain merged in the water for a longer period of the year are also constructed with PPC cement. In Manufacturing Portland Pozzolanic Cement ( PPC ) : Because of its pozzolanic properties, flyash is widely used in the manufacturing of portland pozzolanic cement. Hence props cannot be removed early. Bleeding is a type of segregation in which some of the water in the concrete mix tens to rise to the surface of fresh concrete. However, the making of OPC has reduced to a great extent as blended cement like PPC has advantages, such as lower environmental pollution, energy consumption and more economical. Portland Slag Cement(PSC) As per the great success achieved by Jagdamba Cement Industries Pvt. PPC cement prolongs the setting time of concrete, hence help in better finishing of concrete. The quality of fly ash can affect the quality and strength of Cement concrete. Disadvantages of Blast-Furnace Slag Cement Early Strength is low; therefore, it cannot be used in Reinforced Cement Concrete (RCC) works. What are the advantages and disadvantages of PPC over OPC? Advantages And Disadvantages Of Cement Concrete Road ... Aug 24, 2018 advantages of cement concrete road 1. The process of hardening of Ordinary Cement lasts by the end time of hydration, while the process of hardening of PPC continues even after the completion of the hydration process. Advantages It is economical as in PPC a part (25%) of costly clinker of OPC cement is replaced by cheaper pozzolanic material. Improved concrete density due to pore refinement. Hydraulic cement is best suitable for the structures which are constantly in the contact with water. 10. PPC is more durable than Ordinary Cement, because of its resistance against Sulfate, water, and other chemical attacks. RHA – Rice Husk Ash. Reduction in the production of calcium hydroxide as PPC cement consumes calcium hydroxide. PPC has high durability than OPC which means the structure will last longer and have longer life. PPC is more resistant towards the attack of sulphates, alkalies, chlorides and chemicals as compared to OPC. This is economical because about 30 to 45 percent of OPC is replaced by natural products; pozzolana/ volcanic ash. PPC is difficult to handle due to its high fineness. Portland Pozzolana Cement are manufactured by using pozzolanic materials as one of the main ingredient. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here. For a limited time get 15% off PPI2PASS products with the code. In relation to this, PPC refers to a form of Portland Cement which is Portland Pozzolana Cement. PPC is manufactured by inter-grinding well-burnt OPC Clinker with gypsum and pozzolanic materials like power-station fly ash or silicious earths. 8 types of warehouses used in USA. PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) portland pozzolana cement are manufactured by using pozzolanic materials as one of the main ingredient. A pozzuolana is a cement extender improving the strength and durability of the cement or even reducing the costs of producing concrete. Setting time is longer than that of OPC. Hence it saves the cost of admixtures. Both cement are used in constructions.However some pros and cons of PPC over OPC are listed below. very widespread, but I am hoping that maybe by studying the general advantages/disadvantages of each platform I can compare the two systems reasonably well. 09. 03. 2. 01. 2. Concrete produced by using PPC is more cohesive. In this article you will learn about the advantages of PPC cement and where it is used. During manufacture of OPC, large amount of chemical gases like OPC emulted but in PPC cement less amount of chemical gases produces as it contains 10% to 25% pozolanic materials. Thus the Chemical composition of Portland Pozzolana Cement is: Preparing for FE or PE exams? The durability of concrete made using OPC is less than that of the concrete made using PPC. PPC is one of them with its own distinctive qualities, that make it popular all around the world.
