Strength-increase mechanism and microstructural characteristics of a biotreated geomaterial

Chi LI, Siriguleng BAI, Tuanjie ZHOU, Hanlong LIU, Xiao QIN, Shihui LIU, Xiaoying LIU, Yang XIAO

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 3, Pages 599-608 doi: 10.1007/s11709-020-0606-7

Abstract: New artificial biotreated geomaterials are produced based on the MICP technology for different parentthis study is to explore the strength-increase mechanism and microstructural characteristics of the biotreatedgeomaterial through a series of experiments.The results show that longer mineralization time results in higher-strength biotreated geomaterial.Therefore, the strength of the biotreated geomaterial is affected by the parent soil properties, mineralization

Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 1, Pages 80-93 doi: 10.1007/s11709-007-0008-0

Abstract: efforts in the past decade for the establishment of a practical approach of digital representation of the geomaterialSuch averaging method ignores the fact that the geomaterial samples are also consisted of a number ofdigital representation for the actual spatial distribution of the different materials and components in geomaterialalso made on how to use the proposed approach to develop the geomechanics by taking into account the geomaterial
