Portland Cement: Properties, Composition, Types and Uses
Limestone comprises approximately two-thirds of the raw material required for making cement. Portland cement consists of four major clinker compounds, Tricalcium Silicate (C 3 S), Dicalcium Silicate (C 2 S), Tricalcium Aluminate (C 3 A), and Tetracalcium Aluminoferrite (C 4 AF) together with the gypsum added during grinding.

CEMENT RAW MATERIALS
The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.

How Much Does Concrete REALLY Cost?
Concrete is made of a mixture of hard, durable aggregates and portland cement bonded with water. These ingredients make concrete highly versatile, malleable, and easy-to-form yet strong and durable. A typical mix is about 10 to 15 percent cement, 60 to 75 percent aggregate and 15 to 20 percent water.
