Explained: Cement vs. concrete — their differences, and ...

 · Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.

The Cement Manufacturing Process

 · Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are ...

POLLUTION DUE TO CEMENT DUST – IJERT

 · Darley et al., noted that plants were stunted and had few leaves in the heavily dusted portions of an alfalfa field downwind a cement plant in California. Furthermore, it was shown that plant height, phytomass, net primary productivity, chlorophyll content, metabolites and yield were reduced in response to cement dust in polluted areas.

Portland cement and the environment

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.
