compound composition as modern Portland cements as the temperature achieved was not high enough for the main constituent mineral of modern cements, tricalcium silicate (C 3S), to be formed. The only silicate present was the less reactive dicalcium silicate (C 2S). The sequences of reactions, which take place during clinker production, are discussed

English bricklayer Joseph Aspdin is widely credited for the invention of modern portland cement. Aspdin received the first patent on portland cement in 1824. He named it "portland" cement because concrete made with it resembled a highly prized building stone quarried on the Isle of Portland.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

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.
With any industrial activity, generation of waste and byproducts is expected. In the case of cement manufacturing, the associated process leads to pollution in the following ways: • Dust generation in specific sections of cement plants (crushers, raw mill, coal mill, kiln, clinker cooler, cement mill) •
