Question
Problem 6: A concrete is mixed and used to cast a bridge deck during a very cold weather with temperatures below -10°C. Answer the followings: 1) What would happen to concrete during early hours after casting? 2) How would this impact the long term properties of concrete? 3) How could you reduce the negative impact on concrete at such low temperatures? Explain? 4) If the same concrete was cast under very high temperatures, answer questions 1-3? 5) If the same concrete was cast under normal temperatures then exposed over many years to freezing and thawing cycles, describe why concrete may be damaged and how to reduce this damage? Is there a similarity between damage mechanisms as a result of casting under low temperatures and that from freezing and thawing? 6) What are the threshold values for moisture content and percentage of saturated pores to cause damage by freezing and thawing? (Hint: Dry concrete will never be damaged by freezing and thawing).
