Portland cement is mainly composed of four primary chemical elements: calcium, silica, alumina, and iron. These elements combine during the manufacturing process to form various minerals like tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite, which contribute to the cement's properties and performance.
Oh, dude, you're asking about the bogus compounds in cement? Well, there's tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite. They're like the troublemakers of the cement world, causing all sorts of reactions and setting the stage for concrete to do its thing. But hey, without them, we wouldn't have sturdy buildings and sidewalks, so props to the bogues compounds, I guess.

Ordinary Portland cement (OPC) is formed through a process called clinkerization, which involves heating a mixture of limestone (calcium carbonate) and clay or shale (silicates) in a kiln at temperatures around 1400-1600°C. This high-temperature process results in the formation of clinker, composed primarily of four mineral phases: alite, belite, tricalcium aluminate, and tetracalcium aluminoferrite. After cooling, the clinker is finely ground and often mixed with a small amount of gypsum to control setting time, resulting in the powder known as ordinary Portland cement. This cement is then used as a key ingredient in concrete and various construction applications.
In cement production, the main chemical reaction is the hydration of compounds like tricalcium silicate (C3S) and dicalcium silicate (C2S) in the presence of water to form calcium silicate hydrates (CSH) and calcium hydroxide (CH). This process leads to the hardening and setting of the cement, creating a strong and durable material.
This type of Cement is manufactured in form of different grades, the most common in India being Grade-53, Grade-43, and Grade-33. OPC is manufactured by burning siliceous materials like limestone at 1400 degree Celsius and thereafter grinding it with gypsum. OPC gives enough comprehensive strength after soaking in water for 3 days, 7 days and 28 days. This is suitable for all types of modern civil engineering construction.
