Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln (referred to as co-processing), replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications.
The types and amounts of cement produced in 2015 were: Portland cement 80.4 million tons; Masonry cement 2.4 million tons; Other hydraulic cement 0.6 million tons; Cement production is predominantly portland cement, which is mostly used in concrete.

Mixed together, cement and carbon black create what is called a supercapacitor—an alternative to a battery that can store a very large amount of electrical energy and release it very quickly on ...
A reduction of 40 percent of Portland cement in the concrete mix is usually feasible when replaced with a combination of pozzolanic materials. Pozzolans can be used to control setting, increase durability, reduce cost and reduce pollution without significantly reducing the final compressive strength or other performance characteristics.
Entrance to the Science Museum of Virginia. A science museum is a museum devoted primarily to science.Older science museums tended to concentrate on static displays of objects related to natural history, paleontology, geology, industry and industrial machinery, etc. Modern trends in museology have broadened the range of subject matter and introduced many interactive exhibits.
The Rosendale region of southeastern New York State is widely recognized as the source of the highest quality natural cement in North America.
