Question

White cement should have the least percentage of?

Answer 1

Hint: White cement as it names suggests is white in colour as compared to classical grey cement. So, for producing the white colour of the cement, the selection of its raw material for its manufacture plays an important role. The materials or raw substances that are light in colour are preferred than dark coloured compounds for the manufacture of the white cement.

Complete answer:
So, to proceed with the question, first we need to know about the some basic properties of white cement.
So, basically white cement is the same as grey cement in fundamental essence but it differs in the colour of the cement.
White cement is made from raw materials with a low content of colouring elements such as Fe, Mn, Cr and Ti. Use is made of high-grade limestone or chalk containing less than \[0.15\] wt. \[\% \] , \[F{e_2}{O_3}\] and less than \[0.015\] wt. \[\% \] MnO, and of white clay, kaolin or by-products of its processing,
All these elements balance the production of white cement and its properties. But one important compound ‘Silica’ plays an important role in the white cement but its quantity should be limited in the white cement.
Silica fumes are extensively concrete because it results in better and improved engineering characteristics constructively.
Therefore, the correct answer is ‘silica’.

Note:
One main reason why white cement is preferred over grey cement at some places. So white cement is best known for its beautiful and attractive white colour, therefore, white cement is extensively used in the prestige building manufacture and for the decoration purposes in the buildings.
