| Abstract: | Two columns, which were made of composite steel concrete of C60 , appeared as serious cracks three months after casting. On the basis of analysis the cracks are caused by too much cement content, temperature reducing in concrete quickly , unauthorized changing in the mix proportion of concrete while casting , and inadequate curing etc. |
| Keywords: | high strength concrete mix proportion of concrete concrete curing |
