We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. we reveal different types of cement products, their compositions, properties, and typical uses. wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types. cement.
The manufacture of portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰c. during this process, these materials partially fuse to form nodular shaped clinker by broking of chemical.
There are more than twenty types of cement used to make various specialty concrete, however the most common is portland cement. 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.
Cement manufacturing process phase 1: raw material extraction. cement uses raw materials that cover calcium, silicon, iron and aluminum. such raw materials are limestone, clay and sand. limestone is for calcium. it is combined with much smaller proportions of sand and clay. sand amp; clay fulfill the need of silicon, iron and aluminum.
Cement manufacturing process. cement is the basic ingredient of construction and the most widely used construction material. it is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
