| Abstract: | The performance, shortage and development trend of the grouting material used in shield tunneling was introduced. The application of lignosulfonate high range water reducer in the grouting material was also presented at the base of superplasticizer mechanism. Some modification ideas of lignosulfonate high range water reducer were proposed from the characters of grouting material. It has great significance for enhancing the value of lignin, protecting the environment that lignosulfonate high range water reducer was applied in the grouting material. |
