everything we use or build or create in modern life involves rock‚ mineral and fuel resources taken from the earth. To categorized these in groups Metallic (platinum‚ gold‚ silver‚ aluminum‚ iron‚ tin) Nonmetallic (diamonds and other precious stones‚ gypsum‚ salt) and Rocks (marble‚ sand‚ gravel‚ granite). It doesn’t matter whether mining and processing iron ore or limestone‚ many of the advantages and disadvantages are common to these operations. Dust from mining quarrying causes air pollutions.

technology is representative in the cement production‚ it use limestone and clay as raw materials‚ after crushing‚ dosing and levigating the raw material was fed to cement rotary kiln ‚ calcined into clinker‚ then levigate into cement by add moderate gypsum( sometimes add some mix material or admixture) . For the preparation methods of raw material are different‚ cement production can be dry (include semi-dry) process and wet (include semi-wet) process. Portland cement ① dry process.

PORTLAND CEMENT Chemical composition. Portland Cement is made up of four main compounds: tricalcium silicate (3CaOSiO2)‚ dicalcium silicate (2CaOSiO2)‚ tricalcium aluminate (3CaOAl2O3)‚ and a tetra-calcium aluminoferrite (4CaO Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols‚ these compounds are designated as C3S‚ C2S‚ C3A‚ and C4AF‚ where C stands for calcium oxide (lime)‚ S for silica‚ A for alumina‚ and F for iron oxide. Small amounts of uncombined
