1. Introduction. Available literature indicate that most studies on occupational health problems in cement milling industries are limited to observable injuries like ventilatory problems (Abron et al., 1988, Alakija et al., 1990, Akahara, 1994).While the use of biochemical indicators to diagnose susceptibilities to organ-system injuries is lacking.
In many industries, TRS performance as a measure of performance is closely linked to ROIC and generation of economic profit. In the cement industry, however, this link is weak. The industry's record of value creation is spotty, with ROIC levels roughly equal to the cost of capital, at around 9 percent.

During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement". If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
üThe cement clinkers are cooled to about 150ºF (51ºC) and stored in clinker silos. üWhen needed, clinker are mixed with 2-5% gypsum to retard the setting time of cement when it is mixed with water. üThen, it is grounded to a fine powder and then the cement is stored in storage bins or cement .
