Chemical Composition of Portland Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds.

Chapter Two Types of Cement

Its cost is higher than ordinary Portland cement – because of the special requirements of material composition, including addition of iron powder to the raw materials. For the hardened cement, the effects of sulfates are on two types: 1- Hydrated calcium

Calcium Aluminate cement (or High Alumina cement) This cement contains 32 – 45% Al 2 O 3 , about 15% iron oxides, and 5% SiO 2 , with the remainder composed of CaO. The primary phase present is Calcium Aluminate, or CA.

13 Types of Cement and their Uses in Concrete

There are various types of cement used in concrete construction. Each type of cement has its properties, uses, and advantages based on composition materials used during its manufacture. 1. Ordinary Portland Cement (OPC) Ordinary Portland cement is the most widely used type of cement, which is suitable for all general concrete construction.

Compound Composition of Clinker / Cement. Four major compounds formed from the oxides under high temperature in the kiln. Name (Oxide Notation) - Shorthand. Tricalcium silie (3 CaO. SiO. 2) –C3S. Dicalcium silie (2 CaO. SiO. 2) –C2S.

Chemical Composition of Cements

A suitable material for the student to operate on is the well known brand —Portland Cement. As the student has already examined in detail a silie, the following notes are given somewhat briefly. A good cement should consist chiefly of SiO2 and CaO, with a little Al2O3 and Fe2O3, and less than 2% MgO, and 1.5% CO2 and SO3. From this the student will see that the accurate determination of
