In the early 1950s, the Davis Company introduced contractors in Southern California to the idea of adding synthetic iron oxide, at the time a waste product from chemical manufacturing, to their gray concrete mix.
This mill at this time produces two types of cement namely Ordinary Portland Cement (OPC) and Pozzolana Portland Cement (PPC). OPC comprises 90%clinker, 5%additive (limestone) and 5 %( gypsum). PPC comprises 70% of clinker, 2529%% pozzolana and 5%gypsum.

A white form of the cement, containing minimal proportions of iron oxide and silica, has outstanding refractory properties. Expanding and nonshrinking cements Expanding and nonshrinking cements expand slightly on hydration, thus offsetting the small contraction that occurs when fresh concrete dries for the first time.

As 1000kg of pure water 4°C = 1 cubic meter, those materials under 1000kg per cubic meter will float; more dense materials will obviously sink. Those materials have a specific gravity more than 1. Pure water at 4°C (the maximum density) was chosen as the accepted standard for specific gravity and given the value of 1.

Iron oxide (Fe 2 0 3): This ingredient imparts color, hardness and strength to the cement. Magnesia (MgO): This ingredient, if present in small amount, imparts hardness and color to the cement. A high content of magnesia makes the cement unsound.
How is Portland cement made? Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, marl, shale, iron ore, clay, and fly ash.
