In cement manufacturing, conditions favorable for formation of nitrogen oxides (NO x ) are reached routinely because of high process temperatures. Essentially all NO x emissions associated with cement manufacturing are generated in cement kilns. In cement kilns, NO x emissions are formed during fuel combustion by two primary mechanisms:

The properties of this particular type of concrete do not depend exclusively on the water: cement ratio and are rather influenced by the size and type of vibrocompression machine employed. Hence, the existing mix design methods for this type of concrete require excessively arduous, expensive, and time consuming tests in concrete plants.
