Solution

Silica is Silicon dioxide $({SiO}_{2})$ .
Calcium oxide or Quick lime combines with sand i.e. silica to form slag i.e. Calcium Silicate.
The reaction is:
$\underset{C a l c i u m o x i d e}{C a O (s)} + \underset{S i l i c o n d i o x i d e}{S i O_{2} (s)} \to \underset{C a l c i u m S i l i c a t e}{C a S i O_{3} (s)}$
Hence, Calcium silicate is formed by the reaction between Calcium oxide and silica.
