| Abstract: | The special climatic conditions in the Gobi Region tend to result in speeding up the losses of the slump of high-performance concrete,the appearing of cracks caused by the early plastic contraction,shortening the setting time,lowering the durance,etc.In the process of the construction of the newly-built Lanzhou-Xinjiang Railway,in order to solve the above-mentioned problems,adopted are the corresponding processes and technical measures in the processes of the design of the mix ratio of concrete,the storage ... |
