Answer
Limitations of concrete as a structural material:
1. It is relatively weak and extremely brittle
2. Large concrete structures can experience considerable thermal expansion and contraction with temperature fluctuations
3. Water penetrates into its external pores which may lead to severe cracking in cold weather due to freeze-thaw cycles
