Q: 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
  • A. frost resistance
  • B. weathering resistance
  • C. chemical resistance
  • D. fire resistance
Correct Answer: Option B - Weathering resistance– It is the ability of a material to endure alternate wet and dry condition, for a long period without considerable deformation and loss of mechanical strength. Fire resistance– It is the ability of concrete to withstand fire or to give protection against fire. Frost resistance– It is the property that concrete resist the role of freeze– thaw cycles without damage when it suffers frost in the saturated state.
