| Abstract: | The requirements for construction of passenger dedicated railway are stringent and accordingly the technical standards and quality goals set for the construction are high.To ensure the concrete quality of bridge piers of the railway and appearance of the concrete to have clear edges and corners,smooth lines,good surface finish and agreeable colors,and also to ensure that cracks will not occur in the concrete and the concrete can satisfy its technical requirements of workability,strength and durability,the mix proportioning of the concrete,the possible causes that will lead to the cracks in the concrete and the relevant construction technology have been studied thorough tests. |
