The ability of a material to endure alternate wet and dry conditions for a long period without considerable deformation and loss of mechanical strength is called:

Right Answer is:

Weathering resistance

SOLUTION

Building materials have an important role to play in this modern age of technology. The rapid advancement of constructional methods and changes in the organization of the building industry may influence the choice of materials.

Physical Properties

Weathering Resistance is the ability of a material to endure alternate wet and dry conditions for a long period without considerable deformation and loss of mechanical strength.

Note:-

Frost Resistance denotes the ability of a water-saturated material to endure repeated freezing and thawing with a considerable decrease of mechanical strength. Under such conditions, the water contained by the pores increases in volume even up to 9 percent on freezing. Thus the walls of the pores experience considerable stresses and may even fail.

Fire Resistance is the ability of a material to resist the action of high temperature without any appreciable deformation and substantial loss of strength. Fire resistive materials are those which char, smolder, and ignite with difficulty when subjected to fire or high temperatures for long period but continue to burn or smolder only in the presence of the flame, e.g. wood.

Chemical resistance is the ability of a material to withstand the action of acids, alkalis, seawater, and gases.
