龙门石窟裂隙防渗灌浆新材料试验研究
Experimental Study on Novel Grouting Materials for Fracture Seepage of the Longmen Grottoes
摘要
Abstract
Water⁃seepage is one of the most serious diseases endangering Longmen Grottoes, impervious grouting is a fundamental way to control seepage. As the early use of superfine cement and epoxy resin materials have poor du⁃rability, severe salinity problem, more effective seepage materials are demanded urgently. In this paper the liquidi⁃ty, shrinkage rate, compressive and flexural strength and other characteristics of five new material formulations which include metakaolin, natural hydraulic lime, sulphoaluminate cement and so on obtained from indoor test are analyzed. Results reveal that the material formulations of metakaolin, natural hydraulic lime, and bentonite are suit⁃able for field grouting. In the field grouting test, the grouting pressure is determined 0. 1⁃0. 4 MPa, and the groutability and grouting parameters are discussed and analyzed. Moreover, for the evaluation of the grouting effect, the curing degree, density, filling degree, bonding degree and other aspects of the grouting materials are examined and analyzed after 28 days. Results show that the grouting effect of the metakaolin is the best.关键词
