Cement Production - An Overview | ScienceDirect Topics

abstract. cement production is an energy-intensive process. the cost of energy constitutes more than 60% of the cost of the cement; hence cement plants have to consider minimizing the cost of energy when planning production. however, there are several challenging issues regarding the production plan.

Health and safety in the cement industry

Health And Safety In The Cement Industry

cement is one of the most widely used substances on earth. making cement is an energy and resource intensive process with both local and global environmental, health and safety impacts. recognizing these facts, several cement companies, initiated the cement sustainability initiative (csi) as a member-sponsored program of the world business council



the total world production of cement is expected to be around 4.4 billion metric tons in 2020<5>. in 2010 cement production was reported by 3310 million tonnes. there is a slight decreased in word cement production in 2015 as china's significant decline in cement production. cement production has showed a good increase again in year 2016. from
