composition of the raw materials. SO3 also appear in cement analysis which comes from adding gypsum (46) % during clinker gridding. The Iraqi and British specification for normal high rapid Portland cement pointed that SO3 content must be between ( )% according to type of cement
Portland cement is made up of four main compounds: tricalcium silicate (3CaO #183; SiO 2), dicalcium silicate (2CaO #183; SiO 2), tricalcium aluminate (3CaO #183; Al 2 O 3), and a tetracalcium aluminoferrite (4CaO #183; Al 2 O 3 Fe 2 O 3).In an abbreviated notation differing from the normal atomic symbols, these compounds.
Composition of Ordinary Portland Cement. The chief chemical components of ordinary Portland cement are: Calcium; Silica; Alumina; Iron; Calcium is usually derived from limestone, marl or chalk while silica, alumina and iron come from the sands, clays amp; iron ores. Other raw materials may include shale, shells and industrial byproducts.
This cement has the same chemical composition as the ordinary Portland cement but is more finely ground. Its 24 hours strength is nearly equal to that attained by ordinary portland cement after 3 days. The use of this cement permits early removal of shuttering thus
At each stage in the cement production process controlling the chemical composition is a priority. All of the cement manufacturing facilities in Minya Portland Cement
The performance of Portland cement in concrete or mortar formation is very well influenced by chemical compositions among other factors. Many engineers usually have little information on the

Ordinary Portland cement is one of the most widely used type of Cement. Types, properties, constituents, manufacture, uses and advantages of Ordinary Portland Cement is discussed. In 1824 Joseph Aspdin gave the name as Portland cement as it has similarity in colour and quality found in Portland stone, which is a white grey limestone in island []

Oct 07, 2017#0183;#32;Portland Cement (PC) is a fine powder which is produced by heating limestone and clay minerals in a kiln and forms clinker. The clinker is grinded to fine powder with addition of small amount of other materials. It is the most commonly used types of cement in the world. It is used as basic ingredients of concrete, mortar, stucco etc.
Composite cements based on combinations of Portland cement with either pfa (pulverizedfuel ash to BS 3892 Part 1) or ggbs (ground granulated blastfurnace slag to BS 6699) generally hydrate at a slower rate than Portland cements to BS 12 and produce a lower temperature rise. This applies to both manufactured blends, and blends produced in the mixer. The level of pfa in such blends is usually
