He is associated with many professional bodies. The large quantity of alkalies causes efflorescence. That would mean an OPC would have to pay 30% tax on all profits. Disadvantages of Low Heat Cement. These are calledas Hydraulic Cements (Portland Cement) … ADVANTAGES AND DISADVANTAGES Advantages: Cement is very strong. 07. It is used for general construction purposes, where special properties are not required like reinforced concrete buildings, bridges, etc. OPC is the basic component used for concrete, mortars, stucco, and other common construction essentials that require cement in the mixture.Ordinary Portland Cement is the most prevalent because of the readily available raw materials in the area where it is produced. Cooled clinker is added to a ball mill of 3 to 5%. Along with pozzolanic materials in specific proportions, PPC also contains OPC clinker and gypsum. OPC cement is more costly than PPC. Its initial strength higher than PPC. All Rights Reserved. The concrete made using OPC cement has lower workability as compared to the concrete made using PPC. Due to the white color of GGBFS, the cement color obtained is brighter colored when compared to conventional cement. 6. It cannot be used for mass concreting as it has high heat of hydration as compared to PPC. Single-member: OPCs can have only one member or shareholder, unlike other private companies. PLC was made by replacing 5 and 10 wt. The initial setting of OPC is faster than that of PPC. Portland stone is white grey limestone within the island of Portland, Dorset. 3. Nominee: The sole member of the company has to mention a nominee while registering the company. Type II: For moderate sulfate resistance. OPC is the most commonly used cement in the world. Here is a quick look at OPC disadvantages: #1. During the manufacturing of cement, silica undergoes a chemical reaction with calcium to form di-calcium and tri-calcium silicates which adds strength to the cement. 10. 02. 1400 – 1500° C. Clinker is produced in a kiln in the form of dark greenish-blue balls. It is not favorable in aggressive weather. 09. Blended cement is obtained by mixing OPC with mineral admixtures or additives like fly ash, slag or silica fumes. Gypsum increase the setting time of cement. Either way, let me know by leaving a comment below. There are two methods for manufacturing of cement as follow: Deficiency of lime causes a decrease in the strength of cement and excess free lime causes unnecessary expansion and disintegration of cement. PPC is made by using a fly ash and it is a waste by-product from coal fired thermal power stations and solves the huge disposal problem and also utilizes the waste product. Thus cement concrete can be prepared by mixing above ingredients in a fixed pro­portion. High ferric oxide content is favourable to the production of high early strengths in cement. Disadvantages of ordinary portland cement: It cannot be used for large-scale concreting because it has a higher heat of hydration than PPC. Know more about the difference, grade of both cement … Prior to 1987, there was only one grade of OPC which was governed by IS 269-1976. PG offers better grinding aid performance with higher Blaine areas. The clinker falls into the rotary cooler & cooled under controlled conditions. 4. Mahadev Desai is the Founder and CEO of gharpedia.com and SDCPL a leading design consultancy firm having strong national presence. He is also co-founder of 1mnt.in the first in Industry software for contractors’ billing. Its resistance to aggressive chemicals is lower than PPC. Ordinary Portland Cement sets more quickly, and attains 85% of its maximum strength within 7 days. PPC= OPC clinker + Gypsum + Fly ash (15-35% by wt. Ltd. Hence, admixtures are added to make concrete workable which affects the overall cost of construction. 2- This cement cannot be used in cold weather conditions. 5. Grasscrete: Sustainable Paving Systems | Types, Advantages & Installation. There are many types of cement in the market to suit every need. Ordinary portland cement is a complex product derived from unprocessed common natural materials like limestone and clay. Rapid hardening cement produces the strength at the age of 3 days is equal to the 7 days strength of OPC cement with the same water-cement ratio. – Know More! 04. Not suitable for large businesses If the paid-up capital of an OPC exceeds Rs.50 lakh and its annual turnover exceeds Rs.2 crore, then the OPC needs to mandatorily convert into a private limited company. The OPC is finer hence higher permeability and consequently lower durability. 03. 3- It is not very suitable for Ordinary structures because the use of cement will delay the time of drying. It is also used as a basic component in a mortar, plaster, and non-speciality grout. PPC and OPC Cement difference: PPC is a pozzolona portland cement whereas OPC is an ordinary portland cement. Now I’d like to hear from you, which section was new to you or maybe I missed something. During the grinding process, a small quantity of gypsum is added. A metered proportion of crushed, dried limestone is fed to the finish grinding mill, along with clinker and gypsum. Hence limestone can be saved by partially replacing OPC with fly ash in PPC. 04. Know the Difference Between Cement and Concrete. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in Sand cement composes of Ordinary Portland Cement (OPC) and sand. 1- Initial strength gained by using LHPC is lower than that of OPC concrete, but the final strength is the same as that of OPC. Today, Cement is the most commonly used cementing material in construction. Excess quantity of sulphur trioxide also makes the cement unsound. OPC is costlier than PPC. Grinding, mixing and burning of raw materials at a temp. OPC has lower fineness, hence has higher permeability and as a result it has lower durability.
