The addition of superplasticizer in cement disperses the cement particles and allows the glassy content of the fly ash to react effectively with the lime liberated by the hydration of the cement to form CSH. The increase in flyash content from 29% to 35% in a cement plant of 5000 tons capacity per day, extra 462 tons flyash can be loaded.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix 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.
