The two minerals that are found in cement are : Silica and calcite.
<u>Explanation:</u>
Different minerals form the composition of cement but the minerals that are most commonly found in cement are calcite which is contained in the limestone.
The other mineral that is used in the production of cement is silica in the form of raw rock type used to make cement which is found in clay. So they form an important part of formation of cement.

<u>Answer:
</u>
The ranking of common igneous silicate minerals based on the temperature at which crystallization occurs is called Bowen’s reaction series.
<u>
Explanation:
</u>
In Bowen’s reaction series the minerals with high crystallization temperature are present at the top layer. This means these minerals are the first to crystallize from the magma and they are mostly unstable. The Bowen's reaction series is represented in the Y shape. The left branch of this Y has minerals containing iron and magnesium. They are called as Ferromagnesium minerals.
The right branch of the Y contains plagioclase feldspars minerals. Temperature gradually decreases down along the Bowen’s reaction series from
to
. At certain low temperature, the two branches combine forming minerals similar to felsic rocks such as orthoclase feldspar, quartz and muscovite mica.
