OPC or Ordinary Portland Cement, as it is called is made of ordinary clinker mixed with gypsum. Ordinary Portland cement is graded according to its compressive strength. There are three grades of Ordinary Portland cement namely, OPC-33 grade, OPC-43 grade and OPC-53 grade. The OPC- 53 is produced using a highly specialised process that allows optimum distribution of each particle, thereby allowing superior crystalline structure and balanced composition. The result is better strength and durability. OPC - 43 grade cement is produced by inter grinding of clinker and gypsum, to an optimum fineness to ensure both strength & durability of concrete at all ages, which it suitable for all construction works.
The process used by cement manufacturing companies in india consists of grinding the raw materials , mixing them intimately in certain proportions depending upon their purity and composition and burning them in a kiln at a temperature of about 1300 to 1500 C, at which temperature clinkers are formed and they are made into fine powder in addition with 3 to 5% of gypsum to form portland cement.

PSC or Portland Slag cement is a kind of blended cement manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement. The Portland Pozzolana Cement (PPC) is a kind of blended cement which is produced by either inter grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions. In my opinion, PSC (Premium Slag Cement) fits the most. Because of the construction qualities, it is ideal for house construction. PSC is a blended cement. Slag is a product that is non-metallic and is 90% glass. With silicates of lime, these qualities make the PSC ideal to be used in mass construction. It posses a lot of strength and does not crack easily and gives a better finish.
1) Ordinary Portland Cement (OPC) Ordinary Portland Cement is one of the most well-known and widely produced cement in the construction world. They are used for general cement construction. Its basic ingredients include mortar, concrete, stucco, and non-specialty grout. You may have seen this cement near almost any construction site. 2) Portland Pozzolana Cement (PPC) Portland Pozzolana Cement is a mixture, prepared by grinding pozzolanic clinker and Ordinary Portland Cement. It is widely recognized for its resistance to chemicals attacks.
The cement industry is one of the prominent industries in India. They play a pivotal role in the overall Indian economy. There are many cement plants in India which provide millions of jobs and fulfill the dreams of building homes in the country. There are many cement plants in the country like Ultratech Cement, Ambuja Cement, Emami Cement Limited, J K Lakshmi Cement, Binani Cement, ACC Limited, Birla Cement etc. However, the largest cement plant in the country is UltraTech Cement and is amongst the World’s top cement manufacturers. The company has a presence in five countries. The total operation includes 11 integrated plants, one white cement plant, one clinkerisation plants, 15 grinding units, two rail and three coastal terminals, and 101 ready mix concrete (RMC) plants. Additionally, the company is the largest clinker exporter in India.
Cement is most often a gray or slightly brownish color due to the presence of coloring oxides in the clinker. For certain applications, usually aesthetic ones, it may be desirable to use a lighter or white Portland cement. White ordinary Portland cement known as “White Cement” is one of the most important raw materials used in construction of a building. White cement with the exception of whiteness has same properties as Gray ordinary Portland cement has. It is as durable and strong as Gray ordinary Portland cement and has high degree of whiteness.
Portland Pozzolana Cement i.e. PPC cement is actually a variant of Ordinary Portland Cement i.e. OPC cement. PPC is made by combining OPC clinker, gypsum and Pozzolanic materials whereas OPC is made by grinding a mixture of limestone and other raw materials like argillaceous, calcareous, gypsum to a powder. Although OPC is used more due to its immediate features the usage of PPC is experiencing a steep rise because it causes less pollution and it is economical. In case you are wondering which type of cement suites best for your purpose contact Emami Cement, one of the top cement companies in India. It manufactures both types of cement and suggests consumers the best type of cement as per their need and requirements.

The Portland Pozzolana Cement (PPC) is a kind of blended cement which is produced by either inter grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions. PPC is widely used in mass concrete works such as dams, spillways, retaining walls, all types of reinforced cement concrete (“RCC”) work, underground structures, bridges, general building works and hydro-power stations.
Portland Slag Cement (PSC) is made by of Clinker, Gypsum and Granulated Blast Furnace Slag. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion. Due to its much lower lime content and lower permeability, slag is effective in preventing efflorescence when used at appropriate levels. From an environmental viewpoint, the use of slag cement in concrete serves to make concrete “greener.” Here are the applications of Portland slag cement: Underground concrete Water storing structures Residential Construction Commercial Infrastructure Roads and Highways Industrial Plants
Both PPC and OPC 53 are best in their own ways as they have different advantages. PPC cement is advantageous due to slow conversion of calcium hydroxide in the hydrated cement paste into a cementitious product. It is economical due to the replacement of costly clinker by cheaper pozzolanic material. It generates reduced heat of hydration and that too at the low rate. Long-term strength of portland pozzolana cement after a couple of months is higher than ordinary Portland cement if enough moisture is provided for continued pozzolanic action
White cement can be useful in filling gaps and cracks if used properly. White cement tends to shrink after drying so a proper mix of cement with sand and water will be helpful for filling the gaps. There are many variants of white cement by different cement companies available in the market. However, white cement prices may differ according to quality. Hence, the best white cement must be chosen according to the budget. Emami Double Bull Subh cement is a premium white cement brand from the house of Emami Cement Ltd, manufactured with high-grade clinker and best quality Ground Granulated Blast Furnace Slag ( GGBFS ) enriched with glass content which is ideal for the optimal setting.

Long-term strength of portland pozzolana cement after a couple of months is higher than ordinary Portland cement if enough moisture is provided for continued pozzolanic action OPC 53 grade cement provides high strength and durability to structures because of its optimum particle size distribution and superior crystallized structure. Being a high strength cement.
Advantages It is economical as in PPC a part (25%) of costly clinker of OPC cement is replaced by cheaper pozzolanic material. Reduction in the production of calcium hydroxide as PPC cement consumes calcium hydroxide. Thus the calcium hydroxide is not produced as much as in the case of ordinary Portland cement. It generates less heat of hydration at a low rate than ordinary Portland cement. Reduction in permeability of PPC offers many other advantages, such as better durability than opc 53 cement. Disadvantages Less rate of development of strength initially than ordinary Portland cement. It reduces the resistance to corrosion of steel reinforcement due to alkalinity reduction. But it improves permeability of concrete considerably. Setting time is longer than opc 53 cement.

It is imperative to select the best type of dust collection system to maximize the gathering process. Before selecting and installing a dust collector, the cement manufacturing plant must be examined to detail. The sizing of the waste removal equipment must be based on the size of the particulates, the properties of these wastes, temperature, flow rate of these particles and the moisture content. When inertial separators are used, it must be ensured that the applied force is enough to collect most of the waste materials. These separators use centrifugal, inertial and gravity. For settling chamber type, the particulate must be provided with adequate space to settle and distil. For cyclone separators, the centrifugal force must provide enough energy to remove all wastes.
