Protecting The Environment: Cement is an energy-intensive product to manufacture, but it is essential to construction. The process may account for up to 7 percent of pollution, such as smog, greenhouse gases and emission from heating fuels such as coal. Using additives to reduce cement …
Portland Pozzolana Cement (PPC) Portland Pozzolana Cement also commonly known as PPC cement. These types of cement are manufactured by using pozzolanic materials as one of the main ingredient. The percentage of pozzolanic material used in the preparation should be between 10 to 30. If the percentage is exceeded, the strength of cement is reduced.

5. Reduction in permeability of PPC offers many other advantages, such as durability. 6. 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.
Cement concrete is an important construction material. Its importance is increasing every day. It is a composite material consisting of a binding material, which is essentially cement, inert mineral Filler, known as aggregates and water. Thus cement concrete can be prepared by mixing above ingredients in a fixed proportion.

Portland cement and process of Manufacturing what is Portland Cement. Portland cement is an extreme ground material having adhesive and cohesive properties, which provide a binding medium for discrete ingredients. It is hydraulic cement made by finely pulverizing the clinker produced by calcining to incipient fusion a mixture of argillaceous and calcareous materials.
and are, therefore, called hydraulic cement. The name "Portland cement" given originally due to the resemblance of the color and quality of the hardened cement to Portland stone Portland – island in England. Manufacture of Portland cement Raw materials • Calcareous material – such as limestone or chalk, as a source of lime (CaO).
Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

For centuries, one of the most common/ commonly materials used in construction has been concrete. Formed from hardened cement, concrete has been used for everything from driveways to home foundations. However, it has a variety of disadvantages that should be considered before use.
There are many types of cement in the market to suit every need. Both Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC) are used in constructions. However, some pros and cons of OPC over PPC are listed below.
Sep 17, 2013· There are 2 chief aspects of the manufacturing process: First To produce a finely divided mixture of raw materials – chalk / limestone and clay / shale. Second. To heat this mixture to produce chemical composition. There 2 main process that can be used in manufacturing of Portland Cement that is. i) wet process ii) dry process; WET PROCESS
Disadvantages of Hydraulic Cement. Hardens very fast, so it must be used within 10-15 minutes of mixing. This type of cement Cannot be used on frozen surfaces, or in areas where the temperature drops drastically within 48 hours.; Not flexible, hence only suitable for providing mechanical support.
Manufacture of Hydrophobic Cement. The process of manufacture of this special cement is same as that of portland cement. The clinkers formed in the manufacture of cement are grinded with water repellent film substance such as Oleic Acid or Stearic Acid.
Dec 03, 2012· CONCLUSION Cement is a binder, a substance that sets and hardens independently, and can bind other materials together. It was first made by Joseph Aspdin in 1824 in England. It is Classified as Natural Cement, Pozzolana Cement, Slag Cement, Portland Cement. Portland cement is most commonly used. Its manufacturing process consists of Crushing ...
