Also Read: Pros and Cons of Ordinary Portland Cement (OPC) Over Portland Pozzolana Cement (PPC) The raw materials are quarried from the local rock and first crushed to size less than 50 mm. The raw materials are ground together in a raw mill. Accurately controlled proportions of each material are delivered onto the belt by weigh feeders.

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients....

What is the raw material for cement? | AnswersDrive

Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

2019-6-23 · Such types of cement are specially made Portland cement in which alkali content is kept below in minimum amount, by exercising very strict control over the composition of the raw material used. They are used in those circumstances where aggregates-for making concreteare suspected to contain reactive silica. 14. Water Proof Cement....
