Bond Failure Mechanism of Fully Grouted Rock Bolts / Jianhang Chen  

Public ISBD Titre : Bond Failure Mechanism of Fully Grouted Rock Bolts Type de document : document électronique Auteurs : Jianhang Chen, Auteur ; Liu, Yongliang, Auteur ; Junwen Zhang, Auteur Editeur : Berlin [Germany] : Springer Nature Limited Année de publication : 2023 Importance : 111 p. Présentation : ill. ISBN/ISSN/EAN : 978-981-9904-98-3 Langues : Anglais (eng) Tags : Civil Engineering  Geoengineering  Foundations  Hydraulics  Shear Stress  Tri-linear Model  Bolt/Grout Interface  Debonding Behaviour  Shear Slipping Index. décimale : 624.151 Géotechnique Résumé : The purpose of writing this book is to provide the latest research findings in ground control techniques in mining engineering, especially the rock bolting techniques. Since rock bolts are widely used in mining engineering and civil engineering, they are significant in guaranteeing the safety of underground openings. However, instability issues still occur with the rock bolting technique. Therefore, it is valuable to understand the exact load transfer mechanism of rock bolts. This book summarised the recent research work regarding rock bolting conducted by the authors. It is valuable for the readers to fully understand the reinforcing mechanism of fully grouted rock bolts. This book focuses on the bond failure mode of fully grouted rock bolts, which is the most widely encountered failure mode in rock bolting. Different investigation approaches are used in this book, including numerical simulation, analytical modelling and experimental tests. Therefore, this bookconducts a comprehensive study to reveal the bond failure process of fully grouted rock bolts. Moreover, it reveals the corresponding bond failure mechanism. Therefore, it helps the reads to fully understand the bond failure mechanism of rock bolting. Moreover, it helps the readers to develop new approaches and methods to prevent failure of the rock bolting system.

Sustainable Cementitious Materials for Civil and Transportation Engineering / Wang, Junjie  

Public ISBD Titre : Sustainable Cementitious Materials for Civil and Transportation Engineering Type de document : document électronique Auteurs : Wang, Junjie, Auteur ; Xie, Jianhe, Auteur ; Liu, Yongliang, Auteur Editeur : Basel [Switzerland] : MDPI Année de publication : 2025 Importance : 270 p. ISBN/ISSN/EAN : 978-3-7258-5666-4 Langues : Anglais (eng) Tags : steel-slag powder  replacement ratio  fracture performance  concrete  tunnel engineering  mechanical behavior under fire  microstructure  carbonation Index. décimale : 620.136 Matériaux de construction artificiels : Pierres, ciments, bétons Résumé : Since its invention, concrete has become the most widely used construction material. Growing concerns over the greenhouse emissions profile of the Portland cement and concrete industry have led to a very high level of recent interest in the development of low-carbon construction materials. The requirements of raw materials for cement and concrete, such as natural minerals, stones, and river sand, have been increasing, especially in developing countries where massive amounts of infrastructure are being built. This trend promotes the requirements of sustainable cementitious materials with low carbon emissions for civil and transportation engineering. The development of low-carbon construction materials has been recognized as a means of reducing the carbon footprint of the Portland cement and concrete industry in response to growing global concerns over natural-material shortages and CO2 emissions from the construction sector. The concrete and cement industry has been under pressure to shift towards sustainability by developing alternative low-carbon cement and concrete materials. However, many fundamental mechanisms in this field require further elucidation. In addition, industrial applications are still scarce due to the gap existing between the fundamental research and industrial use in this area.
