Materials used for the construction of Prefabricated Structures (PFS) often have thermal insulation properties to enhance energy efficiency and comfort.

Question 9

Which method is not adopted in precasting?&#10;A)tilting mould method&#10;B)long line method&#10;C)extrusion method&#10;D)static method

Accepted Answer

The static method is not a recognized method in precasting. Precasting involves methods like tilting mould, long line, and extrusion to shape and create precast concrete elements, but the static method does not pertain to a specific precasting technique.

Question 10
