| Abstract: | Concrete cracking is a characteristic attribute possessed by its materials.This paper presents an effective method to control cracking in the extra long structure of large volume concrete laid as one-piece, focusing on the major causes of the forming cracks in the laid mass concrete, to balance out shrinkage stresses and integrated application of combining material selection and other construction techniques. |
| |
| Keywords: | extra long structure concrete cracking shrinkage-compensating internal stress calculation |
