Jun 25, 2018· The Portland pozzolana cement is manufactured by mixing ordinary portland cement with 10 to 25 percent of the pozzolanic material. The pozzolanic material may not posses cementitious property but it is a material which essentially contains silicious or aluminous material.
The results show that cement's hydration heat decreases as the rate of additives (e.g., obsidian) increases from 20% to 50%. The cement's fineness greatly affects its hydration heat. Increasing the refinement of pozzolanic material to a certain level (30%) leads to …
Portland Pozzolana Cement is used in the construction of buildings near seashores, dams, marine structures, dams, and other constructions in damp places. Underwater bridge piers and abutments are also constructed by means of this type of cement. For the construction of hydraulic structures. Used in the construction of massive structures like ...
Other articles where Pozzolanic cement is discussed: concrete: …continued to be the primary pozzolanic, or cement-forming, agent until the early 1800s. In 1824 an English inventor, Joseph Aspdin, burned and ground together a mixture of limestone and clay. This mixture, called portland cement, has remained the dominant cementing agent used in concrete production.
PPC at PARASAKTI CEMENT is produced Conformed to the Indian Standards Specifications as per IS: 1489 (Part 1) - 1991 (Flyash Based) A hydraulic cement prepared by grinding the mixture consisting of an intimately and uniform blend of Portland clinker and pozzolana with the suitable addtion of gypsum or an intimate and uniform blending of Ordinary Portland Cement and fine pozzolana material.
Advantages of Portland Pozzolana Cement: Pozzolana Portland cement is an environmentally friendly cement because the materials used in construction are made from natural recycled waste. It is a very good cement when it is used for plastering works. Pozzolana has silica content that makes it cheaper and therefore reduces the cost of cement.
Jan 25, 2018· Pozzolana Portland cement (PPC) is manufactured by combination of pozzolanic materials. Pozzolana is an artificial or natural material which 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

Answer (1 of 6): Pozzolana cement (IS: 1489-1991) : The pozzolana is a volcanic powder. It is found in Italy near vesuvius. It resembles surkhi which is prepared by burning bricks made from ordinary soils. It can also be processed from shales and certain types of clays. The percentage of pozzolan...
Pozzolans as Cement Replacements. Typically pozzolans are used as cement replacements rather than cement additions. Adding pozzolans to an existing concrete mix without removing an equivalent amount of cement increases the paste content …

Pozzolanic materials are siliceous and aluminous materials, possessing little or no cementitious value by themselves, but in finely divided form and in the presence of moisture react chemically with calcium hydroxide liberated on hydration of cement at ordinary temperature to form compounds, possessing cementitious properties.
Pozzolana is volcanic ash that is used as a mixture in cement to provide strength and resistance to wear and tear from the elements and chemical breakdown. Pozzolana gives traditional concrete more workability as well as increased durability. Pozzolana is named after the city where it was first discovered, Pozzuoli in the Campania region of Italy.
Portland Pozzolana cement is integrated cement which is formed by synthesising OPC cement with pozzolanic materials in a certain proportion. It is commonly known as PPC cement. In this article we discuss about the properties, manufacture, characteristics, advantages and disadvantages of Portland Pozzolana cement.
Portland pozzolana cement improves pore size distribution and also reduces the micro cracks in the cement paste at the transition zone due to pozzolanic action and being finer than OPC. 7. A 50 kg bag of the Portland pozzolana cement gives more volume of mortar than ordinary Portland cement as the fly ash is finer and of lower density.
The term "pozzolan cement" is derived from the name of a friable volcanic rock—pozzolana—used in ancient Rome as an additive to lime in the production of hydraulic cement.

Portland pozzolana cement is suitable for concrete works underground, in water, or humid environment, especially for projects requiring impermeability, freshwater resistance, and sulfate corrosion resistance, such as hydraulic structures, marine structures, dam construction, construction near the seashore, sewage disposal construction, etc.
When using pozzolans in mortars, the softer pozzolanic materials (like brick dust from clay bricks fired at less than 950°C) will normally make them more permeable and flexible, while the hard-burned materials, for example PFA (pulverized fuel ash, like fly ash), will tend to produce a harder mortar, closer in its characteristics to cement.
Pozzolana is a natural or artificial material containing silica in a reactive form. Though it does not possess cementitious properties, it can chemically react with calcium hydroxide, when finely divided, at ordinary temperature to form compounds (calcium silicates) possessing cement properties.
