Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and nonspecialty was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...
The aesthetic properties of concrete blocks, once utilitarian and gray, have become more important. Concrete block manufacturers now produce concrete blocks in a wide range of colors, textures and finishes that architects utilize to great effect, depending on the building design.
Manufacture of White Cement. The manufacturing process of white cement is same as that of grey cement, but the selection of raw material is an important part in the manufacturing process. The oxides of chromium, manganese, iron, copper, vanadium, nickel and titanium imparts the grey colour to the cement.
White cement is the same as that of grey Portland cement but the only difference is in the colour and fineness. This colour of this cement is determined by its raw materials and the process of manufacture. In this article, we study the manufacture, properties, uses and difference of white cement. Manufacture of White Cement
