On the other hand, the modulus of elasticity of OPC at initial age is higher than PPC, and at a later age, it is lesser than PPC. He has a degree in Civil Engineering (BE) and Law (LLB) and has rich experience of 45 years. Hence it is more suitable for plaster, masonry and mortar work. It is used in drainage and sewage and sewerage systems. It reduces the resistance to corrosion of steel reinforcement due to alkalinity reduction. 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. Thus the calcium hydroxide is not produced as much as in the case of ordinary Portland cement. For the construction of hydraulic structures. Mass concrete structures because of less liberation of heat. Specific gravity of slag cement ranges from 2.85 to2.94, depending upon the slag cement source-as compared to 3.15for Portland cement. Barrages, which remain merged in the water for a longer period of the year are also constructed with PPC cement. Advantages It is economical as in PPC a part (25%) of costly clinker of OPC cement is replaced by cheaper pozzolanic material. Advantages It is economical as in PPC a part (25%) of costly clinker of OPC cement is replaced by cheaper pozzolanic material. Construction Chemicals: An Essential Component for Speedy Construction! The pozzolana present in the cement increases the fineness and decreases the water content in the cement. As at a later stage of hydration, the hardness of PPC is greater than that of OPC, therefore a huge foundation, high walls, dams, and other gigantic structures are made with PPC. 10. It does not prevent the reinforced steel from corrosion due to the alkalinity reduction. Slag cement should be substituted for Portland cement on a one-to-one basis by mass. Underwater bridge piers and abutments are also constructed by means of this type of cement. 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. the expansion of the construction industry it is necessary to develop low cost and more efficient types of … get price. The word Portland is used because the inventor of this cement “Joseph Aspdin” of England in 1824, used the very first cement for the first time to set the stone namely “Portland”. PPC has lower the alkalinity contain which reduces the resistance to corrosion of steel reinforcement. Generally, the mix proportion of 1:3 and 1:4 is used for repairing of concrete and filling the holes and cracks. PPC has high durability than OPC which means the structure will last longer and have longer life. 2) PPC has lower the alkalinity contain which reduces the resistance to corrosion of steel reinforcement. In Manufacturing Portland Pozzolanic Cement ( PPC ) : Because of its pozzolanic properties, flyash is widely used in the manufacturing of portland pozzolanic cement. Hence it is more suitable for plaster, masonry and mortar work. Underground basements are constructed with PPC, as it is resistant to moist surrounding. As a result of bleeding, the top surface becomes too wet and concrete will become porous, weak and … portland pozzolana cement are manufactured by using pozzolanic materials as one of the main ingredient. 04. Used in the construction of massive structures like bridge piers, dams, and other thick foundations. 01. ● Setting time is longer than opc 53 cement. Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials act as a binder. For a limited time get 15% off PPI2PASS products with the code. Get Price; Uses of Portland Pozzolana cement. Ltd. Cons of OPC over PPC: 01. 11. Advantages And Disadvantages Of Cement Concrete Road ... Aug 24, 2018 advantages of cement concrete road 1. concrete roads have a long life. 06. Improved concrete density due to pore refinement. Sthapati Designers & Consultants Pvt. The pozzolana present in the cement increases the fineness and decreases the water content in the cement. – Know More! PPC prevents bleeding. These types of cement are manufactured by using pozzolanic materials as one of the main ingredient. It is not resistant to erosion and weathering action. Thus the calcium hydroxide is not produced as much as in the case of ordinary Portland cement. Sheathing in construction, its types and material used in it. 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.
