摘要：

Based on orthogonal test design, the mix design of cement based anchoring capsule was optimized. Through the direct analysis and range analysis of the orthogonal test results, of the four factors, lithium carbonate has the strongest effect on the performance of anchoring capsule, while the effect of gypsum is the least. The optimal combination is 710 kg/t of sulphoaluminate cement, 190 kg/t aluminate cement, 0.92 kg/t of lithium carbonate, 16.2 kg/t of sodium carbonate and 96 kg/t of gypsum. The prepared anchoring material has superior performance. Furthermore, the strengthening mechanism of cement based anchoring capsule is discussed. (C) 2018 Elsevier Ltd. All rights reserved.
