Answer»

The correct choice is (a) CEMENT

To explain I would say: Cement MORTAR is used to fill the joints in precast concrete floors. Concrete GUNS are used for this purpose. The floors can be CONSTRUCTED very easily with the help of precast beam-slabs. These are generally available in 25 cm width.
