The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in This has made it the prominent concrete for development of huge number of solid and robust structures. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. Portland-pozzolana cement shall conform to IS 3812 : 1981 subject to the requirements specified in 4.1.2 and 4.1.3. Portland-pozzolana cement (PPC) is produced by grinding together Portland cement clinker and artificial pozzolana (Fly ash) with this addition of gypsum or calcium sulfate. The newly formed varieites of cement are now equally acceptable in general construction and specific uses as well . The percentage of pozzolanic material used in the preparation should be between 10 to 30. Pozzolanic substances have a range of uses in construction, including the following: Used in the manufacture of Portland Pozzolana cement (PPC). Pozzolana was first found at Puteoli near Naples where huge amount of bed of pozzolana found in Italy, natural pozzolana is composed mainly of a fine chocolate-red volcanic earth. Used as a soil-stabilisation material. These types of cement are manufactured by using pozzolanic materials as one of the main ingredient. गुण और उपयोग ) Pozzolanic material history extended up to roman time. It consists of 15-35% pozzolanic material, 4% gypsum and the rest is clinker. Portland Pozzolana Cement !! Use of dispersive clay as construction material requires treatment such as by chemical addition. Pozzolana is abundant in certain locations and is extensively used as an addition to Portland cement in countries such as Italy, Germany, Kenya, Turkey, China and Greece. It is widely used for hydraulic structures (mass concrete works) such as dams, weirs, etc. Portland Pozzolana Cement (PPC) Garima Cement (PPC) is manufactured with high quality clinker and superior quality flyash. ( Pozzolana is a naturally siliceous, aluminous and volcanic material extracted directly from volcanic mountains. Advantages and Use of Ordinary portland cement. The basic difference lies in the percentage of clinker used. The company sells its cement under its premium brand name - BIRLA GOLD. Pozzolana is an artificial or natural material which has silica in it in a reactive form. Thus, it is important to understand properties of each type of cement and their uses. Difference Between OPC Cement and PPC Cement. Properties and Uses ( पोर्टलैंड पॉज़ोलाना सीमेंट !! Uses of PPC: PPC is more durable than Ordinary Cement, because of its resistance against Sulfate, water, and other chemical attacks. Portland pozzolana cement (PPC): manufacturing, properties and uses. Portland Pozzolana Cement (PPC) OPC is a fine powder prepared from a mixture of limestone and clay minerals and 2 to 3 percent gypsum is added to it. Portland Pozzolana Cement also commonly known as PPC cement. Used as a filler mineral in asphalt roads, helping to fill voids in the tar. Portland Pozzolana Cement (PPC) – It is a kind of Blended Cement which is produced by either intergrinding of OPC clinker along with gypsum and Pozzolanic materials (Pozzolanas) in certain proportions or grinding the OPC clinker, gypsum and Pozzolanas separately and thoroughly blending them in certain proportions. These types of cement are manufactured by using pozzolanic materials as one of the main ingredient. Manufacture ! A reduction of 40 percent of Portland cement in the concrete mix is usually feasible when replaced with a combination of pozzolanic materials. Thus, this cement is the product of ordinary Portland Cement and Volcanic Ash. Compared to industrial by-product pozzolans they are characterized by larger ranges in composition and a … If the percentage is exceeded, the strength of cement is reduced. Portland Pozzolana Cement is manufactured by grinding the OPC clinker with 10 to 25 percent of the pozzolanic material. It has been possible to upgrade the qualities of cement by using high-quality limestone, modern equipment, closer on line control of constituents, maintaining better particle size distribution, finer grinding and better packing. j. Supersulphate cement. Pozzolans can be used to control setting, increase durability, reduce cost and reduce pollution without significantly reducing the final compressive strength or other performance characteristics. Other uses of pozzolana. Portland Pozzolana cement. Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. It is composed of (70% -80%) of Portland cement, added to that a ratio of (15-20%) of Pozzolana. Portland Pozzolana cement is produced by synthesizing OPC cement with pozzolanic materials in a specific ratio. Uses: a. ; Fly ash is a very fine material produced as a residue precipitated electro-statically or mechanically from the exhaust gases of a coal-fired thermal power station. The motivation for the production of Blended Cement has been primarily with the … Pozzolana is the name of ash released as a result of a volcanic eruption. Portland Pozzolana Cement (PPC) PPC is a type of blended cement. Various types of cement such as Ordinary portland cement(OPC), portland pozzolana cement(PPC), Rapid hardening cement, etc are available in the market.
