| Abstract: | It analyses the causes of the bulk concrete construction quality problems in bridge. It describes the construction control measures which are used to decrease concrete thermal stress and prevent cracks of concrete. it introduces the measures against bulk concrete fractures, such as optimum match ratio design, construction technique, temperature control and maintenance in order to improve construction quality. |
