The raw materials needed to make ordinary portland cement are,
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
Ordinary Portland cement is the most common cement used in the world, made from stucco, concrete, mortar and other materials. Slag cement is usually mixed with Portland cement and is the substance leftover after metal has been smelted from raw ore.
Type-I - Ordinary portland cement used in general constructionType-II - Portland pozzolana cement , moderate heat of hydrationType- III - Rapid hardening cement used for quick setting worksType-IV - low heat cement, low heat of hydrationType-V - Sulphate resisting cement used in sewage linings,marine construction.
The specific gravity of Ordinary Portland Cement (OPC) - 43 grade typically ranges from 3.10 to 3.15. This value indicates the density of the cement relative to the density of water, providing insight into its composition and quality. Specific gravity can vary slightly based on the manufacturing process and the raw materials used.
Ceramic floor tiles need an acrylic fortified thinset. The acrylic can be added as a liquid or can be already in the mix. There are premixed thinsets available on the market. These are not preferable since they are often not as strong. _________________________________________________________________________________ The cement used for fixing ceramic tiles is white cement or ordinary portland cement. The white cement gives better bonding than the ordinary cement. The use of white cement will not be economical when compared to ordinary cement.
Ordinary Portland cement (OPC) is by far the most important type of cement.The OPC was classified into three grades, namely 33 grade, 43 grade and53 grade.High heat of hydrationInitial setting time is 10 minsFinal setting time is 10 hrs.It is used in construction of buildings, bridges, hydraulic structures,etc.,
Masonry cement is similar to OPC but has a plasticiser added to the cement powder. As a bag of masonry cement contains 75% cement powder and 25% plasticiser, a higher proportion of cement must be used.
Cement is classified into different types based on their chemical composition and properties. Common classifications include Portland cement, which is the most widely used type, as well as blended cements, such as fly ash or slag cements, and specialty cements like white cement. Each type of cement has specific applications and characteristics.
Ordinary Portland Cement sets more quickly, and attains 85% of its maximum strength within 7 days. OPC is most valuable in large construction projects Portland Pozzolana Cement (OPC mixed with fly ash) takes longer to get to full strength, but it is more eco friendly, because it neutralizes otherwise toxic fly ash, and it is more resistant to corrosive environments. PPC can be used in most situations that OPC can.
Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
Some of the additives used in portland cement are,GypsumCoal dustMagnesiaAlkaliesIron oxide
Ordinary Cement is used for ordianry works like building walls, and other ordinary structures.Generally OPC or PPC are ordinary cements.Special cements are used for special works of greater importance.Special Cements are white cement, colored cement, hydrophobic cement,etc.,
