Domestic cement production has been increasing steadily, from 66.4 million tons in 2010 to about 80.5 million tons of Portland cement in 2014 according to the U.S. Geological Survey 2015 Cement Mineral Commodity Summary. The overall value of sales of cement was about 8.9 billion, most of which was used to make an estimated 48 billion worth of ...
Read MoreCement is a basic material for building and civil engineering construction. Cement is a finely ground, non-metallic, inorganic powder when mixed with water forms a paste that sets and hardens. World cement production has grown steadily since the early 1950s, withincreased production in developing countries, particularly in Asia. 3

Read MoreCement and Concrete Basics. In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Read MoreDec 28, 2018 Cement is the second most-consumed resource in the world, with more than 4 billion tons of the material produced globally every year. As a result, the industry generates approximately 8 percent of global CO2 emissions, not far behind the agriculture industry, which accounts for 12 percent.Ranked with CO2 emissions from individual countries, the cement industry would be the third-highest ...
Read MoreDec 07, 2018 Cement production can also be enhanced by Industry 4.0 in a number of ways. See Exhibit 1. In particular, 4.0 solutions can better manage the enormous energy consumption, rising cost challenges, and overall process complexity that are inherent to the industry.
Read MoreCement 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.
